In February, mechatronics lead Kevin Bass of Intuitive Machines and contracted pilot Mike Laible successfully flew multiple runs with an unmanned aerial vehicle platform, Tiburon Jr., on the coast of Antarctica.
The long-range Tiburon Jr. takes Antarctic ice sheet studies to new heights.
From Wilkins Aerodrome in the southeast, the team launched Tiburon Jr. and collected valuable testing and environmental data. Battling harsh weather and constantly changing conditions, the team flew the UAV several times, allowing tests of all aspects of its platform.
“These flights provided us with valuable insights into cold-weather flight characteristics,” Bass said. “We successfully demonstrated that our onboard flight system is hardened the proper amount for the harsh environment.”
The onboard software also proved to be robust as it dealt with sensors whose response to the extreme conditions was not previously known.
With an 80-knot cruise speed and a 15-minute assembly, deploying a Tiburon Jr. UAV saved time and is significantly safer than manned flights in hazardous environments such as Antarctica, Bass explained.
Tiburon Jr. can be assembled in 15 minutes, an important feature in extreme environments.
The carbon-fiber Tiburon Jr. has a swappable nose cone, enabling a modular ISR sensor pod including visible, infrared and multispectral options. A remote ground station can accompany the ground transportation trailer for a portable stand-alone solution. Aircraft operations can be fully autonomous or man-in-the-loop.
The flight was conducted in cooperation with the University of Texas Institute for Geophysics and ICECAP (Investigating the Cryospheric Evolution of the Central Antarctic Plate).
For its climate change studies, ICECAP currently uses an upgraded World War II era DC-3 with a suite of geophysical instruments to map the thickness of the ice sheet and measure the texture, composition, density and topography of rocks below the ice.
Beginning in summer 2017–18, Tiburon Junior’s big brother, Tiburon, will join the survey team.
Esri’s latest version of ArcGIS Full Motion Video (FMV) presents new capabilities to improve the way analysts and managers interact with videos.
ArcGIS FMV allows users to view, organize and analyze video from drones and other collection platforms.
The new release includes a performance boost in playback and panning, and in zooming the video during playback. It offers full support for JP2, and TIFF support for video mosaics including full image transformations for better accuracy. A new search tool makes it easier to find video segments based on location, time, and selected features.
“ArcGIS FMV expands the capabilities of ArcGIS as a complete, professional platform for managing, sharing, and extracting value from geospatial data,” said Gerald Kinn, Esri’s lead product engineer for imagery. “Imagery from video is one of the most important sources of data in ArcGIS.”
The previous version of ArcGIS FMV included a multiplexer tool that allowed users to transform non-MISB format videos, such as from UAVs or drones, into MISB-compliant videos compatible with the FMV add-in.
“ArcGIS FMV tools add a dimension to our remote sensing analysis not previously possible,” said Verne LaClair, general manager for Vertex Geo, an Esri partner that specializes in civilian, municipal, defense and intelligence initiatives. “The ability to map FMV content will play an important role in search-and-rescue operations, wildlife tracking and monitoring, and cinematography projects.”

Esri has launched two new ArcGIS apps for field operating efficiency at the Esri User Conference, being held June 27–July 1 in San Diego. Attendees can see live demonstrations and experiment with Drone2Map for ArcGIS and Survey123 for ArcGIS.
“These two apps are already becoming game changers,” said Esri President Jack Dangermond. “What we’ve done is make it much easier for our users to collect data, including imagery, and then right away start working with that data — mapping, analyzing, sharing—in ArcGIS.”
Drone2Map for ArcGIS provides safe and affordable imagery on demand—a benefit especially useful to people who work in land analysis or infrastructure inspection and those monitoring events such as natural disasters and environmental change. Drone2Map takes still imagery captured by a drone and quickly turns it into high-quality 2D and 3D products in ArcGIS.
The app detects camera and sensor parameters and intelligently applies appropriate defaults. Its rapid-process capability allows teams in the field to be sure they’ve captured everything they need to avoid costly return trips. The imagery products created using Drone2Map can be used for analysis in ArcGIS Online and ArcGIS Pro to support informed decision-making.
Esri Survey123.
Survey123 for ArcGIS is a simple yet powerful form-centric field data gathering solution that makes it possible to create, share, and analyze surveys in three easy steps. With Survey123, paper forms are effectively transformed into digital surveys. Surveys, from simple to sophisticated, are authored and then shared in ArcGIS.
Using the Survey123 mobile app for iOS, Android or Windows, teams in the field capture survey results with their smartphones and tablets, even in disconnected environments. Data captured in the field is immediately available for analysis in ArcGIS to help users make better decisions. Survey123 is a versatile data collection solution already popular with people in public health, education, public works, disaster response, and humanitarian agencies.
Attendees of the Esri User Conference can see live demos and get hands-on experience with both of these new apps along with hundreds of other solutions designed to enable a smarter world.

In Northern Idaho, not only is the Silver Valley near Kellogg one of the richest silver mining areas ever, but it is also the focus of an extensive EPA Superfund cleanup. There are more than 600 mine and prospecting sites in Shoshone County alone. So how do we sort through them and figure out where buildings were, and what sites were actually developed?

Using aerial photography and GIS technology, historians, archaeologists and environmental scientists are able to look into the past and determine what actually occurred at individual sites. The United States Forest Service (USFS) and the United States Department of Agriculture (USDA) took aerial photographs of the entire area in 1937, 1948, 1965 and 1974. Other years, they partially photographed the area. Since then, aerial flyovers have been replaced by satellite imagery. All of this data tells environmental scientists where to look for waste materials.
It also tells archeologists where to look for old structures and other manmade features. Because before a mine site can be cleaned up, it’s history must be documented. Between historic imagery and modern satellite coverage, this task is made simpler.
Archaeologists all over the world are applying these same techniques, so it comes as no surprise that the 2016 TED Prize, awarded annually, went to space archaeologist Dr. Sarah Parcak of the University of Alabama at Birmingham, whose wish is to: “…discover the millions of unknown archaeological sites across the globe. By creating a 21st-century army of global explorers, we’ll find and protect the world’s hidden heritage, which contains humankind’s collective resilience and creativity,” she told the Alabama News Center.

Parcak first earned international attention by satellite mapping Egypt using infrared imagery, discovering “17 potential unknown pyramids, 1,000 tombs and 3,100 settlements.” At the heart of her program is an online, citizen scientist, interactive platform that will allow anyone to discover ancient sites from space. The same information and imagery gathered over time will allow her and her teams to monitor looting.
The program works simply: Once users take a quick tutorial, they are “dealt” a series of images from a deck with a general location like Northern Italy. The images are of a 50-meter-square area, and have already been processed to simplify the explorer’s search. The exact GPS location is encrypted similar to the way patient data privacy is preserved in Electronic Medical Records (EMR) to protect the exact location from potential looters and unethical archeological expeditions.
All potential discoveries, once vetted, will be passed along to authorities along with the GIS data, so they can then excavate or protect the sites. This enables archaeologists not only to detect sites, but to find and stop looters in a matter of days or weeks rather than months or years.
GIS can play a huge role in these and other archeological projects, and with the integration of virtual reality, the possibilities are even more exciting.
Georeferencing Maps and Historical Photos
While this is not possible with all sites, historical photos of some areas give archaeologists clues of where to start looking for more recent structures and human activity. Georeferencing ancient maps and photos or drawings where possible show what features have changed, what has remained the same, and what impact modern human activity has had on the site.

“Rebuilding” Structures
Once foundations and other evidence of structures have been found, 3D modeling software such as Esri CityEngine can be used in conjunction with photos to virtually reconstruct buildings, terrain and other features. This gives archeologists and scholars insight to how each site might have been used, and what other evidence to look for.
Virtual Reality
As 360-degree cameras have become more affordable and portable (with the release of several new models like the Nikon KeyMission 360), filming sites once they have been visited in this comprehensive way will allow archaeologists who are unable to physically reach the location to “look” for evidence, and offer advice and insight to those on location.
Explorers in Parcak’s programs who make new discoveries will be able to accompany archaeologists via Periscope, Skype, Google Hangouts and social media, all of which are headed toward 3D video capability, allowing for more immersive and meaningful visits.
Infrared photos from space allow us to see things on the ground not previously visible. Three dimensional modeling allows us to visualize structures no longer there, and 360-degree video and virtual reality allow us to visit these places from far away.
The way we discover new things about our world and the way we explore them is changing, and much of that change is possible due to the blend of GIS and virtual reality.
Troy Lambert is a freelance writer, editor and thriller author living in Boise Idaho. He became interested in using GIS for unique applications while at a museum, and now looks for and writes about unique ways GIS is used and can be used to change our world.
Photogrammetry software company SimActive is releasing a new version of Correlator3D with a redesigned aerial triangulation (AT) module.
Correlator3D is a patented end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery, including UAVs.
The tie point extraction and bundle algorithms have been enhanced, along with the added capability to address problematic input data (such as low overlap projects).
The release features an alignment tool that automatically registers new projects to older mosaics and DEMs. It removes the need for recollecting ground control points (GCPs). In addition, a new semi-automatic workflow was developed for GCP tagging.
“Our significant R&D efforts on the AT are due to its substantial impact on all subsequent results,” said Louis Simard, CTO of SimActive. “As such, the release vastly improves and simplifies the entire production chain.”

Aerial images from a drone are being evaluated as a method to survey seagrasses scarred by boat propellers.
The Texas Parks & Wildlife Department (TPWD) has partnered with Texas A&M University-Corpus Christi to determine if using unmanned aircraft systems is as effective as using planes.
Seagrasses serve as a refuge and nursery ground for fish, shrimp and crabs. They provide oxygen to the water column and serve as an area for growth of drift algae, a food source for shrimp, fish and crabs.
A law prohibiting the uprooting of seagrasses coast-wide was passed by the Texas Legislature during the 83rd legislative session and has been in effect since September 2013. Motorboats cause propeller scarring when they drift into shallow waters and tear a trough in the bay bottom.
Michael Starek, assistant professor of engineering, has been analyzing the images and data collected from flights in December of a small UAS about 450 feet above Redfish Bay’s seagrasses.
TPWD has conducted aerial surveys since 2007 using piloted aircraft flying at an altitude of about 2,000 feet, said Faye Grubbs, Upper Laguna Madre ecosystem leader with TPWD.
The project will compare the output from each method, and analyze costs of processing and ease of mobilization.
TPWD continues to collect aerial imagery in four areas along the Texas coast to evaluate the effects of the regulation. Based on the outcome of this project, Grubbs said the department may use drones for not only monitoring changes in propeller scarring, but possibly for mapping other habitats as well.
“We are comparing the accuracies of the different imagery sets — manned versus unmanned — and how well we are able to map scar features observed in the imagery,” she said.
UAS-collected imagery has the potential to change environmental monitoring at many scales, not just in coastal regions, Starek said.
The first step is to show drone-captured data is comparable to that collected from manned planes. University researchers have been doing just that for several years, flying along the coast and comparing drone-captured images to data from on-the-ground and in-the-water surveying by traditional means.
One of the biggest challenges with aerial imaging of the sea floor is weather and water clarity, Starek said.
“This experiment showed that with proper flight planning for weather conditions, mapping of prop scars with a small UAS can be a viable alternative to more costly, piloted airborne surveys,” Starek said. “Results from the flights show impressive spatial fidelity in the UAS-collected imagery. Pixel resolutions down to one inch will allow mapping of seagrass impacted by prop scaring at very fine spatial detail previously unattainable.”
Although the results show the capabilities, Starek said UAS technology still has to evolve both in platform endurance and in regulations to allow these systems to fly autonomously over much larger areas, such as an entire bay system. This latter component will evolve as the technology and confidence in its use matures.
“In the not too distant future, I can foresee the day when a fleet of small UAS equipped with cameras can routinely map an entire bay system at a fraction of the cost for traditional piloted airborne surveys,” he said. “The potential for UAS technology is immense.”
Unmanned aerial vehicle maker DJI has launched the Phantom 4, a quadcopter drone that uses highly advanced computer vision and sensing technology to make professional aerial imaging easier.
The Phantom 4 expands on previous generations of DJI’s Phantom line by adding on-board intelligence that make piloting and shooting great shots easier through features such as its Obstacle Sensing System, ActiveTrack and TapFly functionality.
“With the Phantom 4, we are entering an era where even beginners can fly with confidence,” said DJI CEO Frank Wang. “People have dreamed about one day having a drone collaborate creatively with them. That day has arrived.”
The Phantom 4’s Obstacle Sensing System features two forward-facing optical sensors that scan for obstacles and automatically direct the aircraft around impediments when possible, reducing risk of collision, while ensuring flight direction remains constant.
If the system determines the craft cannot go around the obstacle, it will slow to a stop and hover until the user redirects it. Obstacle avoidance also engages if the user triggers the drone’s “Return to Home” function to reduce the risk of collision when automatically flying back to its take off point.
With ActiveTrack, the Phantom 4 allows users running the DJI Go app on iOS and Android devices to follow and keep the camera centered on the subject as it moves by tapping the subject on their smartphone or tablet. Perfectly framed shots of moving joggers or cyclists, for example, only require activating the ActiveTrack mode in the app.
The Phantom 4 understands three-dimensional images and uses machine learning to keep the object in the shot, even when the subject changes its shape or turns while moving. Users have full control over camera movement while in ActiveTrack mode — and can move the camera around the object while it is in motion as the Phantom 4 keeps the subject framed in the center of the shot autonomously. A “pause” button on the Phantom 4’s remote controller allows the user to halt an autonomous flight at any time, leaving the drone to hover.
By using the TapFly function in the DJI Go app, users can double-tap a destination for their Phantom 4 on the screen, and the Phantom 4 calculates an optimal flight route to reach the destination, while avoiding any obstructions in its path. Tap another spot and the Phantom 4 will smoothly transition towards that destination making even the beginner pilot look like a seasoned professional.
The Phantom 4’s camera, an aerial-optimized 4K imaging device, has undergone an upgrade that includes improved optics for better corner sharpness and reduced chromatic aberration. The Phantom 4 also has DJI’s signature Lightbridge video transmission system onboard, allowing users to see what their camera sees in HD and in real-time on their smart devices at a distance up to five kilometers (3.1 miles).
The Phantom 4’s form factor, the classic quadcopter, has been redesigned and redefined to emphasize elegance and smoother, more aerodynamic lines. Its frame incorporates a lightweight composite core to provide enhanced stability and more agile flight. The core features a redesigned gimbal that provides more stability and vibration dampening, and has been repositioned for a better center of gravity and to reduce the risk of propellers getting in the shot.
Refinements to motor efficiency, power management and a new intelligent battery have extended the Phantom 4’s flight time to 28 minutes, which means more time in the air to capture professional photos and video.
DJI crafted the Phantom 4 with reliability in mind, including redundant inertial measurement units (IMUs) and dual compasses onboard. It uses new push-and-lock propellers that are faster to install and more secure in flight.
In addition to intelligence and ease-of-use, the Phantom 4 is built for fun, DJI said. Its new “Sport Mode” for advanced flyers gives a taste of what drone racing feels like. In “Sport Mode,” the Phantom 4 can fly 20 meters per second (45 miles per hour) and ascends and descends more rapidly than in other modes. The craft’s acceleration and top speed in “Sport Mode” also mean it can reach locations for shots faster and capture shots users couldn’t get before.
“Though the Phantom 4 is easy to use, let’s not forget it is a high-performance aircraft powered by unparalleled DJI technology,” said Senior Product Manager Paul Pan.
When I entered the civilian part of my GIS career as the GIS manager for the Atlanta Regional Commission, I tried to get first responders interested in GIS. Of course, in the early ’90s we were happy to be able to accurately draw points, lines and polygons on a piece of paper. Soon we had the luxury of ortho imagery as a backdrop for our GIS data, but I still couldn’t build a lot of enthusiasm among those first responders.
That changed completely when we started using metric oblique imagery provided by Pictometry. I realized that since we live in an oblique/3D world many non-GIS users had real difficulty visualizing objects or locations using two-dimension visualizations such as drawings, blueprints, maps or even ortho imagery.
By contrast, oblique views made visualization much easier for the vast majority of non-GIS users, and use of oblique imagery coupled with GIS tools exploded. Since then, many of us have been searching for faster, easier and cheaper ways to collect oblique imagery and video, and build 3D models.
For more than a decade, major defense contractors developed leading-edge systems to capture and exploit aerial imagery and video. Although effective, as one would expect of new custom technology, the systems were very expensive and out of reach for most local government agencies. Remote GeoSystems seems to have developed a system that leverages current technology to provide capabilities that may address some of those needs at a reasonable price.
Remote GeoSystems is in the business of capturing, displaying and managing “georeferenced” video and imagery. The company has designed and built high-end geospatial video recording systems for full motion video (FMV) and GIS mapping software primarily aimed at regulatory compliance of energy corridors, grids and critical infrastructure inspection applications.
Fortunately, my UAV is a DJI Inspire 1. I chose the Inspire because of its reputation, and because it seems to be the best combination of features needed for first-responder work at a prosumer price (about $3,500). The Inspire can record up to 4K video/12-mp stills, has a 94-degree field of view so there is no wide angle “fish-eye” distortion typical of an action camera, and has “Lightbridge” technology that permits positive control up to 3 miles and the ability to stream live 720p video (now 1080p) back to the ground controller.
The controller can feed large-screen video for command center group viewing via an HDMI output. Most important, the Inspire records GPS position data and altitude along with the video/imagery stream. (The DJI Phantom 3 Pro is a cheaper alternative that also records telemetry data, but if one upgrades to a 4K camera and the Lightbridge transmitter/receiver, the price approaches the integrated Inspire 1 price.)
An .srt file.
Since I’m always leery of marketing pieces and company demos, I wanted to try the system myself, and Remote Geo was happy to oblige. My first hands-on test was very satisfying. The LineVision software downloaded, unpacked and loaded quickly with no problems. I then recorded some aerial video of our condo building on Lake Guntersville near Huntsville, Alabama. I chose this building because it was convenient, safe to fly and a multi-story building in the open.
In addition to recording the video, one needs to turn on the DJI Inspire metadata recording to generate the .srt file. This is done in the DJI application “General Settings/Camera” by toggling “Video Caption” on. The .srt file was initially designed to provide altitude and location data as on-screen captions, but the data can be used as needed for other purposes.
When done with the flight and recording, transfer the video file and .srt file to your computer. Make sure the video file .mov/.mp4 and .srt file are in the same folder. Open LineVision and you will see an ArcGIS window. From the pull-down menu, load the video and you will instantly see the video play in a separate window with red position dots on the ArcMap view. As the video plays, the dot associated with the location of the UAV will turn yellow. If you click on any dot, the video will jump to that location/position on the video.
Here are screen captures of LineVision showing the ArcGIS view of an ortho image with red dots illustrating the path of the UAV:
One advantage of LineVision for first responders is that it is a complete package with ArcGIS embedded, all for a price well below $1,500. There is no need for a separate ArcMap license. Additionally, although LineVision Esri ArcGIS can display GIS data from online sources, if you have GIS data for your location loaded on your computer the system will operate in a disconnected remote environment. These sample screengrabs don’t do the system and video justice, since I recorded at 1080p rather than 4K. My laptop, this website and the reader’s playback equipment limit accurate playback of 4K content, so I did my work at 1080p.
I can envision a disaster-response scenario where the response team arrives on site, launches a UAV, and starts recording the scene. The captured video could then be loaded, viewed, indexed and cataloged with GIS data overlays on a laptop all in a matter of minutes, even in a disconnected environment. Hours, days or months later, finding the right video clip for analysis or forensics should be significantly easier and faster.
With the explosion of UAV hardware and software, it’s going to be an exciting year as new smaller, cheaper and more capable systems hit the market. Remote GeoSystems is working with UAV manufacturers to make LineVision capability available for many of the newcomers.
Leveraging UAV and LineVision capability, Skyline has worked with Remote GeoSystems to bring yet another capability: rapid 3D model creation. Taking appropriate geo-located frames of the video, Skyline uses its PhotoMesh software to build fully metric 3D models in short order. The full capability of this system and its 3D viewer TerraExplorer is so extensive that I will cover it in a future column, after this month’s ESRI Federal Users’ Conference. If you see me at the UC Feb. 24-25, please stop me and say hello.
UAV company DJI is offering its first tuned propulsion system designed for all-weather use in industrial applications and filmmaking.
The E2000 propulsion system has the power to handle add-ons such as computing devices and advanced imaging equipment. It uses a combination of 6010 motors, 1240S/X field-oriented control (FOC) electronic speed control (ESCs), and 2170 propellers to carry payloads of 1800–2500 grams (g) per axis, with a maximum thrust of up to 5100 g/rotor (50V, sea level).
The 6010 motor’s bearings are fully sealed to prevent flu
ids such as salt water from causing corrosion. A special surface coating applied to the stator also greatly improves its ability to withstand rusting.
To more effectively dissipate heat generated under intensive industrial use, the 6010 motor features an integrated centrifugal cooling system that effectively cools the motor while keeping dust and micro particles out. The 1240S FOC ESC is equipped with a silica thermal pad and heat sink for maximum heat transfer and dissipation.
The E2000 is available in Standard and Pro versions to meet the demands of professional and industry users. Both the 6010 Standard and Pro motor bearings are fully sealed to prevent fluids like rain, pesticide, and salt spray from entering and causing corrosion. A special surface coating applied to the stator also greatly improves its ability to withstand rusting.
The same effective weather sealing has also been applied to the external 1240S ESC found with the E2000 Standard. The E2000 Standard has an IP56 rating.
UK aerial mapping company Bluesky has reduced the time taken to process the terabytes of data captured by more than 75 percent, which will speed the production of aerial photography.
Following a major research project, the team at Bluesky’s Leicestershire production facility has implemented an UltraMap system from Microsoft, which has allowed for the introduction of a continuous, uninterrupted processing workflow. By investing in an entirely new workflow, Bluesky has also improved the quality of the aerial images, reducing “building lean” and image distortion, and the accuracy of its digital height models.
Bluesky’s investment in software follows the recent purchase of two UltraCam Eagle cameras, also from Microsoft, and the introduction of new flying practices.
Bluesky has recently secured a number of high-profile contracts, including a multimillion pound contract for the supply of geographic data to Central Government organizations awarded by the Department for Environment, Food and Rural Affairs (DEFRA), and a four-year contract to supply the national mapping agency for Great Britain, Ordnance Survey.
Earlier this year, Bluesky announced plans and commenced data capture for the first high-resolution aerial survey of the whole of the Republic of Ireland, and will also create digital surface models and terrain models.
“2015 has been a phenomenal year in terms of data volumes to be processed,” said Bluesky’s Technical Director James Eddy. “We have introduced new flying methods, we have secured a number of large contracts and we are actively pursuing our own ambitious flying program. This has meant the volume of raw data to be processed is unprecedented.”
Microsoft UltraMap is an end-to-end photogrammetric workflow system that provides highly automated processing capabilities, allowing Bluesky to rapidly generate quality data products from UltraCam cameras. The improved workflow is designed to process huge amounts of data in the shortest possible time with the highest degree of automation, supported by guided manual interaction, quality control tools and powerful visualization.
“In order to process the many terabytes of data produced in a flying season — for example, we are looking at over a trillion DSM (digital surface model) points alone — the UltraMap system is just one component of a complex system,” continued Eddy. “We have also invested significantly in hardware, including an array of multi core processors, our network infrastructure, a robust backup system, internally produced software to increase and improve QA and improve productivity, and of course, perhaps most importantly, skilled and experienced staff.
“We now believe we operate one of the most advanced aerial imaging processing facilities in the UK, if not the world and we have the capacity to handle our largest-ever projects.”
NM Group is nearing completion on an aerial mapping project covering more than 16,000 kilometers of United Kingdom rail network.
In 2014, NM Group was engaged to map the rail assets with a mix of high-tech laser measurement and imaging equipment, as part of a project to improve asset maintenance, operational effectiveness, efficiency and safety.
The project used a mix of specially commissioned lidar and high-resolution multi-angle cameras mounted on helicopters, carrying out aerial operations and ground-control activities over a four-month period and completing it before winter. The survey information was rapidly transported to NM Group’s Technology Centre in Knaresborough, North Yorkshire, where a team of specialists have been converting nearly a petabyte of raw data into a wide range of terrain, asset and imaging outputs.
“I am incredibly proud of the way our team has responded to this large and challenging project, completing the data capture within an unprecedented timescale and producing a high-quality output that will serve the rail network for years to come,” said NM Group’s CEO Kevin Jacobs.
NM Group’s contribution to the program provides the geospatial fabric on which other layers are overlaid, the basis for asset location mapping and the start point for the design of upgrades and modifications. Traditionally, this information would have been created by a visit to the site by a team of surveyors.
The new method will significantly reduce the need for future field work and trackside access. It will also facilitate more efficient maintenance, allowing crews to identify and access assets more safely and efficiently than in the past, via apps on a range of mobile devices, NM Group said.
NM Group is a specialist service provider of asset management, surveying and mapping solutions to sectors including energy transmission and distribution and road and rail transport. Applying a range of remote sensing and geospatial technologies, the company offers a full range of services from data acquisition through to analytics and web applications for wider access to information.
Autodesk is joining with Skycatch, an aerial data-capture company, to make it easier for designers, engineers, architects, BIM managers, owners and operators to capture and use aerial data. Autodesk is a design and engineering software company for the manufacturing, building, and media and entertainment industries.
Autodesk and Skycatch will use high-resolution aerial data collected by Skycatch to transform the way industrial sites are surveyed. A Skywatch blog said this would mean “allowing companies to make smarter data-driven decisions, while saving time and drastically reducing costs, while Autodesk ReCap delivers an easy, cost-effective solution to process the collected data.”
“Industry professionals using Autodesk software can leverage highly accurate visual intelligence captured and processed by Skycatch’s end-to-end UAV technology to provide invaluable insights into their projects and improve overall efficiency and collaboration across their teams.”
