This map depicts the proposed body of work for 3DEP in Fiscal Year 2015. The BAA awards will add more than 95,000 square miles of 3DEP quality LiDAR data to the national database.
The U.S. Geological Survey National Geospatial Program is developing the 3D Elevation Program (3DEP) to respond to growing needs for high-quality topographic data and for a wide range of other three-dimensional representations of the nation’s natural and constructed features.
To expand awareness of 3DEP status and plans, as well as provide an open forum for 3DEP stakeholders to communicate and coordinate potential Broad Agency Announcement (BAA) proposals, the USGS is offering numerous state and regional coordination workshops.
The primary goal of 3DEP is to systematically collect 3D elevation data in the form of light detection and ranging (LiDAR) data over the conterminous United States, Hawaii, and the U.S. territories, with data acquired over an eight-year period. Interferometric synthetic aperture radar (ifsar) data will be acquired for Alaska, where cloud cover and remote locations preclude the use of LiDAR in much of the state.
The 3DEP initiative is based on the results of the National Enhanced Elevation Assessment that documented more than 600 business uses across 34 federal agencies, all 50 states, selected local government and tribal offices, and private and nonprofit organizations. A fully funded and implemented 3DEP would provide more than $690 million annually in new benefits to government entities, the private sector and citizens.
3DEP is a “Call for Action” because no one entity can accomplish it independently. 3DEP presents an opportunity for collaboration between all levels of government to leverage the services and expertise of private-sector mapping firms that acquire the data, and to create jobs.
“When partners work together, they can achieve efficiencies and lower costs so that 3DEP can become a reality,” the USGS said in a press release. “When 3D elevation data are available to everyone, new innovations will occur in forest resource management, alternative energy, agriculture, and other industries for years to come,” the USGS said.
Geodetics Inc. has teamed up with Silicon Valley’s Velodyne Lidar. Velodyne and Geodetics will work on a variety of initiatives to enhance each others technologies and products with the goal of offering a small-size integrated inertial navigation and LiDAR-based mobile mapping payload for UAVs and other autonomous platforms.
Payloads will include Velodyne’s HDL-64E, HDL-32E and VLP-16 real-time LiDAR systems combined with Geodetics’ Geo-iNAV inertial navigation systems.
Geodetics and Velodyne are exhibiting this week at AUVSI’s Unmanned Systems Show in Atlanta, being held May 4-7 (booth 1500J and booth 2838 respectively). See our show coverage page for more information.
Velodyne’s LiDAR sensors are the highest performance LiDAR systems on the market in their size, weight and power class. Geo-iNAV is a fully-integrated GPS-aided inertial navigation system that provides real-time, high-precision positioning and navigation for manned and unmanned air, sea and ground vehicles. It combines GPS and proprietary sensor fusion technologies to achieve centimeter-level real-time positioning and navigation for dynamic platforms.
“We’re delighted to work with Geodetics to ease the integration process for our customers,” said David Oroshnik, Technical Sales Engineer, Velodyne LiDAR. “Our decision to support Geodetics is based upon the growing demand for cost-effective, small-sized, fully-integrated mobile mapping payloads that deliver performance traditionally associated with higher-end systems.”
“Velodyne’s LiDAR systems enable Geodetics’ products to reach new markets and customers by delivering high performance in a smaller package and for a lower cost than competing devices,” said Lydia Bock, Geodetics president and CEO.
With recent advances in unmanned vehicle technologies, the GNSS ecosystem has expanded to support such mission-critical applications as mobile mapping. These applications increasingly require more accurate navigation to accomplish their mission. The Geo-iNAV family of inertial navigation products delivers this capability with features that support reliable and precise navigation with a low SWaP (size, weight and power) profile for autonomous vehicles and payloads on manned vehicles.
Geo-iNAV is offered in several configurations designed to meet a wide range of requirements. It is available in commercial as well as SAASM configurations, meeting a wide range of inertial navigation application requirements.
The Geospatial Solutions staff is reporting live from Unmanned Systems 2015, held May 4-7 in Atlanta. The event convenes the global community of commercial and defense leaders in intelligent robotics, drones and unmanned systems, hosted by AUVSI.
Check back throughout the week for event updates, including news, photos, videos, tweets and more.
Optech will be exhibiting its latest lidar and imaging solutions at the Unmanned Systems 2015 Conference in Atlanta, Ga., May 4-7, at the Teledyne Booth 2311. Optech’s solutions include a fully implemented lidar/camera workflow for UAV operations, as well as other airborne, mobile and stationary sensors.
Visitors can drop by the booth to learn more about Optech’s UAV solution, which combines the rugged Optech ILRIS terrestrial laser scanner and the new Optech XR6 photogrammetry small UAV with an integrated software workflow. The solution merges aerial camera imagery from the UAV with high-resolution data from Optech lidar to deliver comprehensive, georeferenced and highly accurate 3D planimetric data. The ILRIS lidar system can also be operated remotely through a web interface.
For advances in airborne sensing and surveillance using mid-size to larger UAVs, Optech will discuss the features of the compact Optech Galaxy lidar system and its PulseTRAK technology, which ensures a continuous operating envelope and steady point density even in rugged terrain, vastly simplifying mission planning, and eliminating “blind zones” — overcoming a long-standing limitation inherent to lidar sensors lacking PulseTRAK technology. Galaxy is compatible with all Optech mounts for integrating digital metric cameras, enabling clients to customize their solution with the right mix of LiDAR, multispectral, LWIR, MWIR and RGB sensors for their application.
Optech will also be showcasing the Optech Titan, a commercial multispectral airborne lidar, which accomplishes highly automated land classification using its separate 532, 1064 and 1550 nm laser channels, and performs combined topographic/bathymetric mapping down to a depth of 15 meters in clear conditions.
Visitors who need rapid coastal monitoring and object detection will be particularly interested in the new Optech CZMIL Nova, Optech’s upgrade of the award-winning CZMIL airborne bathymetric mapper. CZMIL Nova maintains its predecessor’s sensing power, including its unmatched turbid water penetration, while boosting installation flexibility and cost savings with a more efficient laser and much lighter hardware, facilitating operation in smaller aircraft.
Skip Miller, UASUSA’s founder and CEO, stands with with the Tempest ET.
UASUSA will unveil its payload advancements in booth 631 at AUVSI’s Unmanned Systems 2015, held May 5-7 in Atlanta.
The new Trimble RTK high-accuracy GPS positioning system will be available through UASUSA. It covers up to 2,300 acres per flight for photo mosaic and mapping missions with manufacturer specified sub-centimeter accuracy.
UASUSA also modified its leading aircraft, the Tempest, to create the Tempest ET. The new aircraft has added payload storage interchangeable in the wing tip extensions, yet still offers the same level of stability, endurance, efficiency and aesthetics as the Tempest, UASUSA said.
The Tempest ET is designed for magnetometer use in the mining industry and offers interchangeable regular, extended and payload tips. With its 10- to 15-pound payload capacity, it may carry the Phoenix Aerial LiDAR system to cover large areas and create survey-grade point clouds.
Great view of the Pentagon while departing from the U.S. Hydro conference held in Washington, D.C.
I’ve attended five conferences in the past couple of months; Esri Water Conference (first one!), Esri Partner Conference, US Hydro 2015, APSG (Association of Petroleum Surveying & Geomatics) and the Esri Petroleum User Group (PUG) conference. It may look Esri-heavy, but the fact is that Esri is doing a really good job of organizing vertical market GIS conferences, and people are showing up. Even with crude oil prices in the cellar (relatively speaking), 1,200 people still showed up at the PUG.
There were a lot of good presentations at these conferences, and I’ll post links to some of them below. Not surprisingly, drones are a major topic of discussion at most GIS conferences. There was even a drone demo (I missed) at the Esri Partner conference showing Esri’s workflow in working with drone-collected data.
If you don’t follow me on Twitter, you might consider it. Twitter is easy and free. When I’m at a conference, I send tweets (most with a photo) in near real-time when I see something of interest. For example, I tweeted when Jack Dangermond showed up at the Esri PUG (he usually doesn’t, but did this year because it was the 25th annual conference) and had something interesting to say (read below). You can sign up for Twitter here, and then choose to follow me at https://twitter.com/GPSGIS_Eric. I get that you may be hesitant to invest any time in this, but it looks like Twitter is becoming the standard for near real-time news (as opposed to other social media such as Facebook or LinkedIn.)
Of all the new technology I’ve heard about over the past few months at these conferences, two subjects continue to excite me.
Drone Mapping. Of course, one of them is drone technology for mapping. It seems like I’ve beat this horse to death over the past few months, but it continues to get juicier and juicier. Technology development in this industry is moving really fast. It seems like new drones are being announced as frequently as new smartphones, maybe more so.
Other ancillary technologies are being developed to support commercial drone operations. For example, in my hometown (Portland, Ore.), a company called Skyward just raised $4+ million in venture capital funding to provide “professional services for UAV operations.” Essentially, the company’s software helps drone operators stay within FAA regulatory compliance.
Last year, the Oregon Unmanned Systems Business Enterprise was formed “with a two-year $882,000 state grant from the Oregon Business Development Department and the Oregon Innovation Council and will be working to match the government money with private investment and other grants.” The organization will award grants up to $75,000. The point is, the money is flowing and it’s a wide-open market.
The drone market is so wide open, in fact, that most drone companies are just buying common airframes and associated parts, putting their brand name on them, and selling them. Perhaps oversimplified, but the point is there’s not much “special sauce” (technology) being added. The manufacturers that aren’t innovating and adding valuable “special sauce” will eventually disappear. Essentially, following are the parts needed for a fixed-wing drone for mapping:
Aircraft components:
Airframe (off the shelf)
Motor (off the shelf)
Servos (off the shelf)
Propeller (off the shelf)
Radio (off the shelf)
GPS (off the shelf)
Autopilot (off the shelf)
Batteries (off the shelf)
Camera trigger (off the shelf)
Camera (off the shelf)
Ground compoments:
900-MHz controller (off the shelf)
Battery chargers (off the shelf)
Mission planning software (off the shelf)
Propeller balancer (off the shelf)
As you can see, all of these components are available off the shelf. You can order each component (maybe all of them from Amazon!), have them shipped to you, and assemble your own UAS for mapping. That said, someone who has gone through the process of building, flying and producing a valuable deliverable that you can make decisions from can add value. But, as competition increases, there’s no doubt that the companies that don’t offer much added value will not be able to operate a sustainable business.
Finally, the U.S. Federal Aviation Administration (FAA) is being surprisingly nimble, approving “333 Exemption” requests at record pace and moving towards using a “summary grant” process to issue bulk approvals of 333 Exemption requests for commercial operations.
UAS presentation from Texas A&M University, one of six FAA-designated UAS test sites.
You may want to take a look at some of the other presentations at the APSG meeting. They were very good. Here’s a quick summary of each by Jon Stigant, long-time member of APSG:
This was a primer in LiDAR technology and methodology — while most of the paper is well understood in the survey community, it is and excellent overview. A reminder for some and a way to fill in the gaps for those not so close to this technology.
Integration of UAVs into O&G Operations — Stacey Lyle, BP (presentation forthcoming)
Stacey provided a valuable summary of the direction in which the FAA is going to regulate the emerging UAV technology. A “must read” for any company that intends to either provide or use this technology. As with most government regulation there is a lot of detail, the devil is in them. Stacey recommended that the APSG engage by developing some standards for the oil and gas industry.
Ron Hughes theme is massive data and managing it — also something of a common theme for all the talks. He focused on automating data processing and recommended a concept of doing this in an automated way with 80 percent of the data. This requires careful procedural development in collaboration with a given client’s business workflows. He gave an example of a large utility company, and how the development of an enterprise metadata server had functional impact for individual business units, but also had the knock on impact of improving inter-functional/inter-community collaboration within the enterprise.
Mike provided input on Geiger mode LiDAR, differentiating Harris’ approach from the more regular LiDAR methodology. The major difference is in data density, data frequency, volume and speed used from higher flying aircraft covering a larger area faster. Providing 10-cm accuracy and expecting 7-cm acuracy development using a/c at 25,000-ft height. Focus on fast processing of immense data volumes (pedabytes) – 24-hour delivery using Harris proprietary processing. Achieve higher density at lower cost.
Mark introduced developments in GIS associated with Common Operating Picture (COP), focusing on the combining of video and data in GIS system. DPFOS mnemonic: Data Management, Planning & Analysis, Field Mobility, Operational Awareness, Stakeholder Engagement. A new SIMOPS (SIMultaneous OperationS). The key is a single source of approved data. Examples of data required in COP from specific disciplines are provided — ROVs, shore clean-up, life of field data, asset and material tracking, live/recorded video, RT data and weather integration, “in the field’” vessel implementation.
GIS, Geospatial, Geomatics…Organizational Capability Evolution — Brian Boulmay, BP (presentation forthcoming)
Rethinking Geospatial Data Management at a major operator. One Map program — not physical, one-way provision. Focus on users vs. geospatial specialists. Users business driven, specialists IT and S driven. Geospatial data integrity and analytics – people, processes and technology. ID goals — massive deployment worldwide — has to be automated. Federated system — regions only have to deal with their own regional data, not be overwhelmed by whole enterprise on their doorstep. IT has the role of providing/maintaining a worldwide solution.
Update on Spring 2014 APSG meeting — All major networks launching satellites. Very soon will have 30 live in-view satellites (U.S., Russia, Europe and China). RTK coverage in China is the best due to BeiDou, supplemented by both Indian and Japanese systems SBAS. $100 RTK on cell phone giving centimeter accuracy eventually, and changing the commercial dynamic!
Set up for managing and analyzing LiDAR data in Global Mapper. Workflows: terrain modeling, visibility, biomass (change monitoring); asset: inspect and maintain pipelines, as-built modeling, simulation. High-accuracy at relatively low cost, outpacing regulatory management. Much public data available — earthexplorer.usgs.gov. xyz values — minimum height threshold, dense RGB point cloud (almost photographic).
Automated dashboard approach, reducing pilot distraction risk, speeding up RT transfer and operational activity reporting.
Esri Conferences
Here are a couple of neat things from the Esri conferences.
First, Jack Dangermond was his usual visionary self at the Esri PUG conference, making his appearance for the 25th annual PUG. He is a master at communicating his GIS vision.
The Evolution of GIS.
In speaking about the evolution of GIS, Mr. Dangermond spoke about the far-reaching impact of email and stated that eventually web-based GIS will be deployed organization-wide, just like email. I agree with this vision. I believe the only question is timing. Is it two years from now? Five years from now? 10 years?
Onto the less visionary and more tactical tidbits…
Of particular interest to me is high-precision GNSS in the Esri environment. A lot of people I talk to are screaming for this. What does high-precision GNSS in the Esri environment mean?
support for high-precision metadata in ArcGIS Collector (ArcPad already supports this).
support for high-precision horizontal (eventually vertical) datum transformations in ArcGIS Collector.
This is important because Esri is supporting ArcGIS Collector across all mobile platforms (Android, iOS and eventually Windows), and people want to use their smartphones and tablets. ArcPad will never run on iOS or Android, so Collector is the GIS collection tool of choice, at least for the Esri environment. It needs to support high-precision GNSS, and by the looks of the following slide, it will. It’s just a matter of timing…
ArcGIS Collector to support high-precision GNSS.
The other potentially neat product Esri announced was Navigator for ArcGIS. Imagine trying to guide a work crew to a buried valve across town (or in the next neighborhood). Displaying a system or region-wide map of valves would not be an efficient way of driving your way across town to find the valve. However, giving a crew turn-by-turn street directions to the street-level, then displaying the valves on that street section, might be a very efficient way of finding the valve.
Fugro has commissioned an additional airborne laser bathymetry system to underpin its position in the development and application of bathymetric LiDAR technology. The combined Fugro LADS Mk 3 and Riegl VQ-820-G systems provide seamless measurements and mapping of nearshore and shallow water environments. The increased capability will enable Fugro to deliver simultaneous topographic and bathymetric surveys in multiple geographical areas.
With high power and frequency, the combined systems achieve superior coverage that minimizes gaps and outperforms lower energy alternatives and single-sensor systems in all conditions, particularly in difficult environments, Fugro said. They are highly adaptable and small enough to be installed in a variety of light aircraft.
With continued operations across the Middle East during 2015, Fugro will also begin a South West Pacific ALB survey campaign following the award of projects in multiple locations to support nautical charting, coastal engineering, scientific assessments, coastal management, benthic habitat mapping and climate change initiatives.
Since 2012, Fugro has operated simultaneous topographic and bathymetric LiDAR systems in France, Japan, New Zealand and the Middle East. Successful results from Japanese coastal areas include returns from the Fugro LADS Mk3 sensor to 50 meters while recent surveys in Saudi Arabia had even more impressive results, with 65-meter depth returns. The deep water returns combined with high-density shallow water and near coastal returns result in a seamless dataset from ridge to deep reef.
Leica Geosystems has announced a group of six major new products for terrestrial laser scanning: three new laser scanners and three new point cloud software products. Together, thes products raise the industry’s bar for laser scanning data quality and productivity, both in the field and the office, Leica said.
Leica ScanStation P40, P30 and P16 Laser Scanners. Leica ScanStations P40, P30 and P16 feature advances in LIDAR and digital imaging as the eighth-generation of Leica Geosystems’ high-performance laser scanners. These new, ultra-high-speed scanners increase field and office productivity, while simultaneously grabbing users’ attention with strikingly sharper, crisper scans and HDR true color images — even under many conditions traditionally difficult for scanning, the company said.
Users will be able to capture more useful data from a single set-up, which translates into fewer instrument setups and greater productivity. Three models meet different user needs: the Leica ScanStation P40 and P30 add survey functionality, longer range capabilities (to 270m for P40), and advanced scanner controls for additional versatility and productivity while the Leica ScanStation P16 is a short-range introductory model.
Point Cloud Software. In addition to the major new software releases Leica JetStream and TruView Global products, Leica Geosystems is now offering Leica CloudWorx for Navisworks — a popular design review application from Autodesk — as its newest family member of CloudWorx plug-ins for CAD and VR applications.
JetStream is a combined project data vault and high-performance data streaming server that takes Cyclone data and serves it up in a high-performance format that enables a CloudWorx user to be up to 40 percent more productive when working with point clouds. Much of that gain comes from instantaneous loading and navigation of point clouds — eliminating traditional “waiting times” long associated with point cloud office work.
Lastly, TruView Global greatly increases anyone’s access to TruViews — Leica Geosystems’ application for viewing and measuring scans. Shaking free from prior constraints, TruViews will be accessible within any Internet browser on any mobile device or computer, with no app or plug-in to install.
Taken together, advances in the new scanners and software elevate laser scanning to a new performance and data quality level, Leica said. The new scanners are all ultra-high speed (up to 1 million points/sec) and can capture more useful data from a scene. In addition, increased user access to TruViews plus good HDR digital images will encourage users to publish TruViews even more frequently.
All of these factors drive users to create more dense scans and larger data sets. With the complementary Leica JetStream software, users have the ability to handle these larger data sets with astonishing ease.
The Leica ScanStation P40, P30 and P16 are immediately available. Leica JetStream, Leica TruVeiw Global and Leica CloudWorx for Navisworks are planned for release Q2 2015.
Topcon Positioning Group has announced the latest edition of its 3D mobile mapping system. The IP-S3 is on display at the SPAR International 3D Measurement and Imaging Conference, held March 30-April 2 in Houston, Texas. The system employs the integration of an inertial measurement unit (IMU) and GNSS receiver with a vehicle’s onboard electronics to offer high-density mobile digital imaging.
“The IP-S3 is more compact, lightweight, and scans at a rate of up to five times faster than previous models,” said Charles Rihner, vice president of the Topcon GeoPositioning Group. “Weighing in at 39 lbs. (18 kg), it’s light enough that a single person could mount it on a car, truck or SUV without any assistance from anyone else.”
Scanning at 700,000 points-per-second, the rotating LiDAR sensor captures the 360-degree environment with 32 internal lasers. The IP-S3’s six-lens digital camera is designed to provide data-rich results with its 30 MP panoramic imagery.
The system pairs with Topcon Mobile Master Field and Office software suite to perform all post-processing functions in a single application.
“The software suite offers a complete all-in-one processing workflow, turning raw sensor data collected by the IP-S3 system into rich and precise point clouds and images,” Rihner said.
“These sessions will provide attendees and members perspectives on some of the major issues facing the profession,” said John Palatiello, MAPPS executive director, and Curtis Sumner, NSPS executive director. “Our goal from the beginning was to provide conference sessions that are distinct from what surveyors experience at their state conferences. These presentations will give conference attendees and members new insights on the geospatial profession, particularly in the commercial market.”
The speakers for Monday, April 13, are listed below, along with the session name.
Michael Anderson, POB magazine, “POB Top 100″
Bryan Baker, Leica, “What You Need to Know Before Starting Up Your Unmanned Aircraft System (UAS) Department”
Pam Nobles, Rob Garster, “What Is Surveying? A Discussion of Infringing Technologies”
The speakers for Wednesday, April 15, are listed below, along with the session name.
Rhonda Rushing and a panel from Berntsen Inc., “Smart Markers for the Nation’s Land & Infrastructure Assets”
Ted Naak, Certainty 3D, “Establishing Requirements, Extracting Metrics and Evaluating Quality of LiDAR Data”
Neil Sandler and a panel from xyHT magazine, “Are You Prepared for Change?”
The overall conference will serve as an umbrella to include plenary sessions, an exhibit hall, and social and networking activities designed to create synergy among the many vertical segments. It will also feature a “conference within a conference” format, in which participating organizations will hold their own meetings and sessions.
MAPPS will host its annual Federal Programs Conference April 14-15. Presentations by federal agencies, the Obama Administration and members of Congress will include briefings on programs, budgets and requirements for the acquisition of geospatial services, data and products by contract from the private sector.
NSPS will host the finals of its annual Student Competition on April 13. The 2014-15 competition will, for the first time, include not only student teams from four-year degree programs, but also teams from two-year degree programs. The NSPS annual General Membership meeting and other business meetings will be scheduled throughout the week in order to allow NSPS leadership to more fully participate in conference activities.
MAPPS and NSPS members will visit some 200 Congressmen and Senators at the U.S. Capitol, advancing a common agenda of legislative issues that serve the public and engage the surveying and mapping community.
Also on the program will be an invitation-only USGS 3DEP stakeholders meeting, a summit by the National Geodetic Survey (NGS) of the National Oceanic and Atmospheric Administration (NOAA) and a licensed geospatial data forum by the Geospatial Management Office (GMO) of the Department of Homeland Security (DHS).
That means you can’t fly drones if it’s related to business, no matter if you charge a fee or not. But, you can fly drones in the United States as a “hobbyist” as long as you adhere to certain rules (such as flying lower than 400 feet above the ground).
In a new twist, the FAA has cracked down on at least one person who posted a drone video on YouTube because YouTube generates revenue, reports the website Motherboard. Even though it appears the drone was being flown by a hobbyist for recreational purposes, it smells to the FAA like a commercial use of drone. Even though the hobbyist isn’t generating revenue from it, Google is.
Jason Hanes’ YouTube channel.
While it appears the U.S. drone community is going nuts using drones for all kinds of non-commercial and commercial purposes, despite the FAA rules, it appears there are too many violators for the FAA to chase after since enforcement notices sent by the FAA have been few and far between. In this case, safety concerns may have been the prompt. The FAA says it’s now looking further into how its safety inspectors send letters like this. Read more about the case at the Motherboard website.
Geospatial Data Interest Crosses Political Party Lines
Senator’s Mark Warner (D-Va.) and Orrin Hatch (R-Utah) introduced the Geospatial Reform Act, targeted at leveraging geospatial data acquired by the U.S. federal government. This bill argues that the federal government is the largest purchaser of geospatial data, yet agencies aren’t required to report details of geospatial data purchased. The bill aims to change that.
“Geospatial data has endless possibilities for transforming both the private and public sectors — from helping local governments develop emergency preparedness plans to fueling the creation of apps that let you find parking spots, restaurants, and even homes for sale based on where you’re standing,” said Sen. Warner. “The federal government is the largest purchaser of geospatial data but some very basic questions about how and where agencies are already investing in this data can’t be answered. Our bill would bring transparency and accountability to the collection of this data and ensure that taxpayer dollars are not being wasted on duplicative efforts.”
In what DigitalGlobe claims is a world’s first, the company began offering commercial 30-cm satellite imagery via its WorldView-3 satellite, which was launched August 13, 2014. DigitalGlobe announced that the imagery is available worldwide (with some restrictions). As part of its press release, DigitalGlobe offered the following quote from PhotoSat, a consumer of imagery.
“DigitalGlobe’s WorldView-3 satellite data is the highest quality satellite photo data that PhotoSat has ever processed,” said Gerry Mitchell, President of PhotoSat, a leading satellite elevation mapping provider for energy, mining, and engineering firms. “In one test, an elevation mapping grid extracted from stereo WorldView-3 satellite photos matched a highly accurate LiDAR elevation grid to better than 15 cm in elevation. This result takes satellite elevation mapping into the engineering design and construction markets and directly competes with LiDAR and high resolution air photo mapping for applications like flood plain monitoring.”
According to DigitalGlobe, WorldView-3 is the first and only commercial imaging satellite capable of collecting imagery with 30-cm ground sample distance, and claims it is five times the detail of the company’s nearest competitor. See a sample by clicking here.
Satellite imagery is approaching aerial photogrammetry quality. I recall Lawrie Jordan, founder of ERDAS (sold to Leica) and now director of imagery at Esri, saying that eventually every square inch of the earth will be imaged constantly by satellite.
Esri and Drone Data Up until now, you haven’t heard the words “Esri” and “drone” mentioned in the same sentence very often. Last week at the Esri Developer Summit in Palm Springs, Esri provided a live map-creation demo using a small quadcopter.
Look for a follow-up article, data example and possibly a video of the event.
DigitalGlobe is making available its 30-cm satellite imagery products. Access to the high-resolution commercial satellite imagery captured by DigitalGlobe’s WorldView-3 satellite will improve decision making, enable more efficient operations, and enhance a variety of applications for customers in the civil government, defense and intelligence, energy, mining and global development sectors.
In addition, many customers who previously relied on aerial imagery can now benefit from the improved economics, global availability, and faster refresh rate that DigitalGlobe can provide with its 30-cm satellite imagery, the company said. Imagery of this resolution was previously only available from aerial platforms, which are difficult, costly, or impossible to access in many parts of the world.
DigitalGlobe’s 30-cm imagery products are also a rapid and affordable alternative in locations where aerial imagery is readily available. New imagery orders can be delivered on timescales of days or weeks, as opposed to months, in many cases, and customers can also have access to a rapidly growing volume of available 30-cm archive imagery.
The suitability of 30-cm satellite imagery for aerial imaging applications is confirmed by the National Imagery Interpretability Rating Scale (NIIRS), which is used by the imaging community to define and measure the quality of images and performance of imaging systems. DigitalGlobe’s 30-cm imagery achieves a rating of NIIRS 5.7, meaning it can resolve objects on the ground such as above-ground utility lines in a residential neighborhood, manhole covers, building vents, fire hydrants, and individual seams on locomotives.
“DigitalGlobe’s WorldView-3 satellite data is the highest quality satellite photo data that PhotoSat has ever processed,” said Gerry Mitchell, president of PhotoSat, a satellite elevation mapping provider for energy, mining and engineering firms. “In one test, an elevation mapping grid extracted from stereo WorldView-3 satellite photos matched a highly accurate LiDAR elevation grid to better than 15 cm in elevation. This result takes satellite elevation mapping into the engineering design and construction markets and directly competes with LiDAR and high-resolution air photo mapping for applications like flood plain monitoring.”
The DigitalGlobe’s WorldView-3 commercial imaging satellite is capable of collecting imagery with 30-cm ground sample distance — five times the detail of the company’s nearest competitor. The satellite also features unique shortwave infrared (SWIR) capabilities that will enable new applications such as seeing through smoke and haze, identifying minerals and manmade materials, and assessing the health of crops and vegetation.
The SWIR imagery that the satellite collects has never before been available to commercial customers with this level of spatial and spectral resolution, and it will provide unique value to users in the energy and mining industries, as well as others, DigitalGlobe said. DigitalGlobe also launched a beta program for 7.5 m SWIR imagery, working with partners, customers and users to explore new uses for this capability.
“Companies should be exploiting the competitive advantages of the WorldView-3 data to look for potential ore-related alteration that will have been missed by the previous satellites used for alteration mapping,” said Dan Taranik, managing director of Exploration Mapping Group, a service provider to the global mineral exploration industry. “Detailed inspection of remote areas on the peripheries of alluvium or younger volcanics would be a competitive advantage that could help reveal concealed deposits.”
