Topcon Positioning Group has released the latest addition to its line of compact digital laser sensors — the LS-100D. The sensor digitally displays the offset value to on-grade, which is designed to help make elevation and vertical alignment control easier and faster for any application.
“The LS-100D features an extra-wide beam capture sensor that also rejects annoying interference from strobe-light exposures,” said Kris Maas, director of construction product management. “The large and bright LCD displays (front and back) feature nine channels of grade information and digitally display the distance to on-grade. By pressing the hold button, the display is locked so the user can conveniently read the results.”
The sensor offers three colored LED’s and a magnet mount for vertical operation, which is designed to be useful for steel erection or operator grade-checking while excavating. Alert icons appear on the LCD if the accompanying Topcon rotating laser instrument is disturbed (HI alert) or when the laser battery is low.
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.”
The latest release of ENVI software, version 5.3, adds significant lidar point cloud analysis and visualization capabilities that previously were only available in the ENVI lidar software package. The Harris Corporation software offers users a single software interface to work with hyper-spectral, multi-spectral, panchromatic and lidar data.
The out-of-the-box functionality includes 3D point-cloud visualization, derived terrain product generation (such as digital elevation models) and lidar analytics such as viewshed line-of-sight calculation.
For users who need point-cloud or terrain products in an area where collecting lidar is not feasible or is too expensive, the ENVI Photogrammetry Module is able to generate synthetic 3D point clouds from stereo optical imagery to take advantage of existing imagery archives.
The dimension of time can be critical for a thorough geospatial analysis of an area, and the new ENVI release has added enhancements to the Spatio-Temporal analysis toolset. Spatio-Temporal analysis visualizes change and derives statistics from data over time, enabling users to observe events of the past to better predict upcoming activities.
New additions were also added to the ENVITask system, a relatively new method for performing discrete bits of image processing programmatically through the ENVI object-based API. This programmatic approach to image processing can save time because users can chain together multiple ENVITasks, allowing the output from one ENVITask to become the input to the next. There are now 138 ENVITasks available in the ENVI API.
3D Services is expanding its services to offer underwater 3D laser scanning in addition to standard 3D laser scanning and aerial surveying.
This new service is designed for underwater inspections. Previously, sonar technology was the main solution for underwater inspections, modeling and measurements. However, sonar does not provide the level of detail necessary for many underwater projects, the Connecticut-based company said.
3D Services is able to provide high-resolution scans and accurate 3D models of underwater structures or topography. It can instantaneously and repeatedly capture accurate data points within less than 1 mm and with a resolution of .01 mm.
The high detail provides the data needed to avoid risks and serious liability-related costs, as well as provide higher quality, more accurate data than before.
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.

Hurricane Patricia — “Extremely Dangerous” Category 5 Hurricane — Is the Strongest Storm Ever Recorded.
Esri is providing a continuously updated hurricane map that shows the projected paths, storm surge, weather warnings and precipitation of Hurricane Patricia, the “strongest hurricane ever recorded.” In addition, the real-time effects of the storm can be seen via social media posts. The website, Hurricanes & Cyclones, is part of the Esri Disaster Response Program.
Hurricane Patricia became the most powerful tropical cyclone ever measured in the Western Hemisphere on Friday morning as its maximum sustained winds reached an unprecedented 200 mph (320 kph).
The National Oceanic and Atmospheric Administration (NOAA) is offering updates through its National Hurricane Center (NHC).
Hurricane Patricia is heading toward Mexico’s west coast, and is expected to make landfall near Puerto Vallarta. “Confidence is high that Patricia will make landfall in the hurricane warning area along the coast of Mexico as an extremely dangerous category 5 hurricane this afternoon or evening,” according to a Friday morning forecast discussion from the National Hurricane Center.
It will then cause massive rainfall in Texas after it hits landfall. “The global models continue to depict the development of a cyclone near the Texas coast over the weekend. This system should be non-tropical in nature. However, this cyclone is expected to draw significant amounts of moisture from Patricia’s remnants, and could result in locally heavy rainfall over portions of the northwestern Gulf of Mexico coastal area within the next few days,” according to the NHC discussion.
The United States Geospatial Intelligence Foundation and the Centre for Spatial Law and Policy have entered into a memorandum of agreement under which USGIF and the Centre will educate the geospatial community on the unique legal and policy issues that impact the collection, use, storage and distribution of geospatial information.
Under the agreement, USGIF and the Centre have created a Geospatial and Remote Sensing Law Working Group. The group will develop training and education materials for GEOINT practitioners, host workshops, and further the GEOINT Community’s understanding of geospatial and remote sensing law.
“The Centre is pleased to be working with USGIF to educate the geospatial community on these important issues,” said Kevin Pomfret, executive director of the Centre for Spatial Law and Policy. “This is also an opportunity for the geospatial community to educate lawyers on where GEOINT is taking the law.”
“As we embark upon the GEOINT revolution, the myriad technological advances related to location and remote sensing are significantly outpacing the development of associated law and policy,” said USGIF CEO Keith Masback. “Decisions are being made daily at all levels of government — in the U.S. and abroad — as courts set precedents gavel drop by gavel drop. This partnership will play a crucial role in organizing a more coherent way forward.”
Next month, the Geospatial and Remote Sensing Law Working Group will host a half-day workshop on legal matters critical to the GEOINT Community as part of USGIF’s 2015 GEOINT Community Week.
The program will include three panels: Government Contracts and Organizational Conflicts of Interest: Conflicts in an Increasingly Conflicted World; Government Contracts and Intellectual Property: Playing a Critical Role in Geospatial Contracting; and Developments in Licensing of Commercial Remote Sensing Satellites. The event will take place Nov. 18 at General Dynamics Information Technology in Springfield, Va. Click here for more information or to register.
A new book published by Esri teaches how to use GIS software to analyze and visualize lidar data. Lidar is an optical remote-sensing system that uses a laser to measure topography, vegetation, objects such as buildings, and the ocean floor at some depths. Data collected from lidar can be used to create highly accurate elevation and terrain models.
Making Spatial Decisions Using GIS and Lidar: A Workbook presents problems that need to be solved using lidar data and the geospatial analysis tools in Esri’s GIS software, ArcGIS for Desktop. The book contains 10 learning modules that focus on how to use lidar data with GIS to answer questions and make informed decisions about real-world situations. Exercises include determining how much land to excavate for an underground parking garage, locating cell-phone towers for maximum signal coverage, placing solar panels based on the amount of solar radiation in an area; analyzing how a coastline has changed after a major hurricane; and making flood insurance rate maps based on hurricane inundation zones.
The workbook covers basic lidar data analysis techniques, 2D and 3D modeling, volumetric analysis, shadow maps, forest vegetation height analysis, and other lidar-related analyses. The book is a college-level textbook for students and geospatial technology professionals and was written with the assumption that readers are familiar with lidar and have some experience using ArcGIS for Desktop software.
Making Spatial Decisions Using GIS and Lidar: A Workbook is the third book in the Making Spatial Decisions series written by Kathryn Keranen and Robert Kolvoord. Keranen is an instructor at James Madison University in Harrisonburg, Virginia. Kolvoord is a professor of integrated science and technology at James Madison University. They wrote Making Spatial Decisions Using GIS and Remote Sensing: A Workbook and Making Spatial Decisions Using GIS: A Workbook, also published by Esri.
Making Spatial Decisions Using GIS and Lidar: A Workbook is available in print (ISBN: 9781589484290; 264 pages, $79.99 or as an e-book (ISBN: 9781589484344). The book is available at online retailers worldwide, at esri.com/esripress, or by calling 1-800-447-9778. Outside the United States, visit esri.com/esripressorders for complete ordering options, or visit esri.com/distributors to contact a local Esri distributor.
Intergraph Government Solutions (IGS) has been awarded a contract by the U.S. Department of Agriculture (USDA) U.S. Forest Service to provide image processing software across the U.S. Forest Service enterprise. IGS is a wholly-owned subsidiary of Intergraph Corporation, a Hexagon company serving the U.S. federal market.
IGS will provide capabilities for core image processing and photogrammetry through Hexagon Geospatial’s Power Portfolio, including ERDAS IMAGINE for remote sensing and IMAGINE Photogrammetry. Integration of these products into the organization allows the U.S. Forest Service to perform mission-critical image processing and analysis on nearly 200 million acres of land for objectives such as forest restoration and emergency response to wildfires.
“The U.S. Forest Service is a long-standing customer of IGS and Hexagon software. This purchase provides the agency with the most advanced geospatial technology for monitoring and managing national forest resources,” said Joe Fehrenbach, CEO and president of IGS.
The result of a competitive best-value procurement, the award includes a base contract period of one year and an additional four option years. As part of the selection process, the U.S. Forest Service required live demonstrations of the proposed workflow technologies with government-provided datasets and rigorous requirements related to multiple areas of need in their business mission.
Figure 1. Suomi NPP/VIIRS night-time light images for Iraq: (a) May 2014, (b) December 2014.
A new paper published in the academic journal International Journal of Remote Sensing analyzed city night lights in Northern Iraq during 2014, suggesting a major loss of electrical power supply within the Iraqi cities seized by ISIS.
The territory controlled by the Islamic State of Iraq and Syria (ISIS) has grown rapidly since the start of the Syrian Civil War, and in 2014 ISIS expanded its control into Northern Iraq. While there are many media reports on violence and geopolitical issues surrounding the takeover of these areas, the impact on everyday life, such as access to electricity for people living in ISIS-controlled regions, is less clear.
In the study, Xi Li and Deren Li (Wuhan University, China) and Rui Zhang and Chengquan Huang (University of Maryland) analyzed city lights as a proxy for the power supply in ISIS-controlled regions between May 2014 and December 2014. The city light data were acquired from the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on the NASA/NOAA Suomi National Polar-orbiting Partnership (NPP) satellite.
The analysis indicates that most of the ISIS-controlled cities, including Mosul and Tikrit, experienced a decrease of more than 90 percent in city light after being seized by ISIS, while the loss of light in cities controlled by the Iraqi security forces (ISF) was very limited. However, the city lights in Ar Raqqa, Syria, ISIS’ de facto capital, did not show a decline after that region was seized by ISIS.
These comparisons suggest that the conflict in Northern Iraq has resulted in a major loss of electrical power supply within the Iraqi cities seized by ISIS, and that this loss is most likely due to lack of access to the Iraqi power grid, rather than a deliberate ISIS strategy of limiting night-time light.
The insurgency in Northern Iraq since 2014 has led to a severe humanitarian crisis, the study authors say. It is widely known that it is extremely dangerous to collect information from ISIS-controlled regions; therefore, the use of remotely sensed night-time light images such as these offer humanitarian agencies and NGOs a low-risk indicator of socioeconomic conditions in war-torn countries like Iraq.
Dr. Todd Bacastow, PSU, talked with me about geointelligence in the broader business community. See the full interview below.
Time for a Revolution — or Evolution
In July at GEOINT 2015 I was talking with long-time colleague Dr. Todd Bacastow. Many of you may know him as the retired Army Lieutenant Colonel and Penn State professor heavily involved in the Geospatial Intelligence Certificate program and the lead for the GEOINT Massive Open Online Course (MOOC) series focused on GEOINT. He proposed a topic for my column that struck a nerve with me since I and others had danced around the potentially heretical issue — is it time to open and expand the GEOINT community to a larger audience?
As retired military officers, Todd and I share a common overarching loyalty and desire to do what we can to make life better and more survivable for our colleagues on active duty. GEOINT has certainly helped by providing detailed and timely actionable intelligence for those at the tip of the spear. However, can we do even better? Most assuredly yes!
The most advanced tip of the spear is our Special Operations community. Manycivilians picture Special Operations members as knuckle-dragging Rambos shooting up the countryside, but nothing could be further from the truth. In fact, they are without doubt the most intelligent, observant and capable people on our DOD team. They’ve learned over decades of experience that they can complete their missions and accomplish far more by winning the hearts and minds of individuals they deal with. Doing that requires hours, days and weeks of due diligence reviewing intelligence and any crumb of information that will make a difference.
Gone are the days of just looking at aerial photography. Now we have countless sources and types of imagery, analytics, tracking, social media, signals and human intelligence. Putting that complex slurry of information together into solid actionable intelligence is everyone’s goal, and the business community is no exception.
Looking around the GEOINT Expo, I saw countless three-letter agency reps, military and homeland security personnel. There were an equal number of defense contractors and related business personnel, but everything was focused on military/security applications. Other than Pitney Bowes showing MapInfo, primarily a business-focused GIS, there were few exhibitors showing technology not aimed at the traditional GEOINT community.
Our military and other first responders have tasks and responsibilities that are serious, complex and becoming more challenging. Limiting the talent pool and body of knowledge to only the narrow GEOINT community is not something we can afford to do. The creative talent found in the broader business community is too valuable to neglect.
Watch the video interview I shot at GEOINT 2015 with Bacastow and Dennis Bellafiore, Ph.D., both of Pennsylvania State University.
My chief concern is bringing the business community in with the understanding that this would be an open and sharing environment. My first real use of GIS after retiring from the Navy in 1993 were some business applications, mostly site studies and trade area analysis. In those early days, GIS grew rapidly within the business community. There were trade shows aimed at business applications of GIS, and even a publication called Business Geographics. Much to my surprise, Business Geographics and associated trade shows died out after only a few years. Some said that everyone learned all there was to learn! I don’t think so. A more likely reason was that the geospatial technology gave businesses a competitive edg.e so there was little incentive to expose trade secrets. Everyone wanted to learn about GIS, but few wanted to open their own kimono.
Would an all-inclusive GEOINT organization run into the same fate? Perhaps if we promote it as “we are all in the same boat” and this is your opportunity to help those at the “tip of the spear.” In this age of cyber warfare and corporate espionage, perhaps we might be able to make this happen by promoting mutual aid and security. I think USGIF and most geospatial industry partners would be interested and very supportive of the idea. But most important, can you imagine the explosion of ideas and the benefits to all geospatial users.
Todd, Dennis and I would really appreciate your opinion. Please leave comments below.
