London building-design agency DCSK is using 3D building models from Bluesky to inform the design of high-profile urban residential developments.
Derived from the most up-to-date and accurate aerial photography, the Bluesky 3D models allow DCSK to place a design within its real-world context, consider sensitive view and vantage points, and communicate ideas to clients, planning authorities and the public.
DCSK has used a number of models from Bluesky, including a detailed representation of central Birmingham for the design of a 24-storey student accommodation on Lancaster Street.
“We have always had to consider how a design sits within the existing cityscape and how it will interact with the buildings and infrastructure that surround it,” said James Khamsi, Director of DCSK. “Before geographically accurate computer representations, such as the Bluesky 3D models, were available and affordable, we relied on a combination of site photographs and traditional 2D maps. This was a crude workflow that raised potential concerns about the currency and accuracy of information that was informing both the design and resulting planning permissions.”
DCSK is using 3D models from Bluesky for projects such as Curzon Circle Student Accommodation and others.Photogrammetrically derived from stereoscopic aerial photography, the Bluesky models are fully rendered and are provided as either wireframe or block models in a format suitable for use in both CAD and GIS software.
All Bluesky 3D models are supplied with a digital terrain model (DTM) depicting the topography of the underlying surface.
DCSK imports the Bluesky data into its 3D modelling software Rhino, where it is used to create a background layer for the design. The development site is isolated, and this data removed from the background layer, allowing for the detailed design to be dropped in. The proposed development can then be viewed and analyzed in its real-world context with detailed assessments of access ways and viewpoints, for example.
“The Bluesky models allow us to inhabit the site and experience the design as if we were there,” said Khamsi. “We can explore potential sensitivities, and, as the models are agile, we can massage the design exploring different options without leaving the office. The Bluesky models are also intuitive and therefore easy to interpret allowing us to communicate complex design ideas.”

“Although recognizing completely different aspects of the business these awards are all significant milestones and accomplishments in their own right and the entire team should be proud of the hard work and commitment they have expended to achieve them,” said MGISS Managing Director and Founder Mike Darracott. “The G-Cloud and Achilles accreditation will put MGISS front and center for the leading players within the public and utility sectors and this will help us capitalise on our work to date with organizations such as Surrey County Council and Wales and West Utilities.
“The Workplace Wellbeing Charter not only recognizes our existing commitment to the health and wellbeing of our team it also gives a benchmark to work from and a toolset to work with to continuously improve,” he continued, “and a happier and healthier workforce will, we hope, make the business even better and stronger.”
Firm will provide geophysical surveying services across multiple states
Dewberry, a privately held professional services firm, has been awarded multiple task orders from the U.S. Geological Survey (USGS) under the Geospatial Products and Services Contract (GPSC) to perform airborne geophysical surveys in portions of Missouri, Illinois, Kentucky, Texas and New Mexico for the USGS Earth Mapping Resources Initiative (Earth MRI).
“Earth MRI is a play on words, as people are familiar with the use of magnetic resonance imaging (MRI) to image inside the human brain,” said Dewberry Project Manager David Maune. “Dewberry is excited to support USGS in its mission to assess critical minerals using airborne geophysical survey technology.”
Dewberry will perform very low-altitude magnetic and radiometric surveys from a fixed-wing aircraft and a helicopter with towed-array sensors to image subsurface geologic structures in search of undiscovered critical minerals and rare earth elements vital for the electronics industry.
These projects, which will be used to evaluate the potential for undiscovered critical mineral deposits contributing to an understanding of the major mineral systems for the two regions, are expected to be completed in early 2021.
With advantages provided by geographic information systems (GIS), the demand for GIS in the telecom industry has increased in recent years. According to a report published by Allied Market Research, the global telecom market is anticipated to garner $3.27 million by 2023.

As technology evolves, the Civil Air Patrol will continue to be a platform for implementing new technologies to secure the country in times of crisis.
The strength of this country isn’t in buildings of brick and steel. It’s in the hearts of those who have sworn to fight for its freedom! —Captain America

If you are someone who likes aviation, GIS and emerging technologies like artificial intelligence and computer vision, and you want to fulfill a greater sense of purpose, the perfect time is now.
The Flying Minute Men, so called by Robert Neprud in the 1948 Story of the Civil Air Patrol (CAP), serve on the frontlines of national threats and disasters. They are the air wing for first responders.
CAP works with many government organizations including the Federal Emergency Management Administration (FEMA), The National Geospatial-Intelligence Agency (NGA), the National Oceanic Atmospheric Administration (NOAA), the Army Corps of Engineers, the National Guard, and many others.
CAP works with non-government organizations too, such as the United States Geospatial Intelligence Foundation (USGIF), the GIS Corps, the National Alliance for Public Safety GIS (NAPSG), and the Red Cross.
CAP also works with youth teaching valuable skills in leadership, community service, STEM and aviation. It has a proud heritage originating in World War II.
In the final days of 1941, the world was in flames. Dark shadows lurked in the waters off American shores. German U-boats attacked ships along the coast. The newly established Office of Civilian Defense understood the importance of aviation for stopping the U-boat threat but lacked the military resources. On Monday, December 1, 1941, six days before the attack on Pearl Harbor, Administrative Order 9 was signed creating the Civil Air Patrol, but there would be no celebration. The threat was all too real. The Battle of the Atlantic had begun. Within a few months Germany sank over 230 ships in U.S. waters. American shores were on fire.
A list of known shipwrecks and their locations in U.S. waters can be downloaded from NOAA’s Coastal Survey website. It is not a complete or a clean dataset so some wrangling will be required. A shortcut is using the shipwreck layer in Google Earth. Along the Atlantic Coast, Gulf of Mexico, and Caribbean Sea there are multiple sunken German U-boats. Most notably are U-85, the first U-Boat sunk by the U.S. Navy in WWII, less than 20 miles off of Nag’s Head, North Carolina (35.885, -75.2829); and U-853, the last one to be sunk in WWII 10 miles off the coast of Rhode Island less than 24 hours before Germany’s surrender (41.2268, -71.4187).

During the War, the Civil Air Patrol flew 5,684 aerial escorts for shipping convoys keeping the sea lanes safe and enabling supplies to get to Europe and North Africa. Shortly after the war, on July 1, 1946, President Truman recognized the valuable contribution made by the Civil Air Patrol making them permanent, but once again there was no celebration. On the same day, responding to overwhelming public attention, TIME published “COSMOCLAST EINSTEIN: All matter is speed and flame.” Radios around the world tuned-in as the clock counted down to zero hour. The first post-war atomic bomb was detonated at 22:00 Greenwich Mean Time (5:00 PM Eastern) in Bikini Lagoon (11°36’00” N 165°29’00” E) over a ghost fleet of ninety-five ships in the middle of the Pacific. History’s long shadow fell over the moment. The applause of a grateful nation for the Flying Minute Men was silence.
It is the mark of real heroes, duty is the highest honor, the rewards are personal having the courage to stand in the face of danger and clasp the hand of Victory. It is valor not fame that makes heroes of normal men and women. The Civil Air Patrol rarely makes the front page, but it supports many of the nation’s most significant events.

The first photographs of Ground Zero released to the public the day after September 11, 2001, were taken by the Civil Air Patrol. With the creation of the Department of Homeland Security in 2002 the Civil Air Patrol took on a much larger role in homeland security. CAP serves a unique purpose flying a multitude of missions because aircraft can fly for extended periods at optimum altitudes to get the best resolution. CAP imagery is often the most currently available and of the highest quality after an event. The Civil Air Patrol aircraft can carry interchangeable sensor arrays, such as thermal cameras, synthetic aperture radars, lidar, communications equipment, and more. Imagery collected by the Civil Air Patrol is publicly available on the CAP GIS Portal.
In 2017, FEMA hosted a Disaster Crowdsourcing Exchange laying a foundation for working with the Civil Air Patrol to push the imagery out to various crowdsourcing channels. The Red Cross Humanitarian OpenStreetMaps Team (HOT) used it to map road networks. Crowdsourced imagery analysts used it for feature extraction and damage assessments. In 2018, this effort was developed further using Hurricane Michael imagery of Panama City, Florida, for creating artificial intelligence algorithms to identify and extract features.
The Civil Air Patrol captures imagery with the WaldoAir XCAM Ultra 50 by flying in overlapping circles as the aircraft sweeps over a disaster area. The overlapping images allow the system to create high-resolution 3D point clouds. The spatial intelligence algorithms employed with post flight processing conducted by Skyline and GeoX can automate feature extraction of buildings, vehicles, bridges, roads, cell towers, and other structures, and identify structures as destroyed, damaged, or undamaged. The system can begin damage assessments almost immediately. The process used to take several weeks with an enormous cadre of specialists and resources and now it can finish in a few days or less with a handful of specialized staff.
I had the privilege of speaking with the Director of Operations for the Civil Air Patrol, Mr. John Desmarais, or Moose as his friends know him. He is a 33-year veteran of CAP, has a pilot’s license, a master’s degree from Embry-Riddle Aeronautical University and is married with two children. Moose shared how September 11th, 2001 changed his commitment and understanding of C.A.P.’s role working with and supporting homeland security missions. He shared with me some of the stories above and gave me an in-depth look into CAP’s future.

Today, the Civil Air Patrol supports important missions. For FEMA CAP does post-event damage assessments after hurricanes, floods, tornadoes, fires, earthquakes, dam bursts, and more. This will be able to get people the assistance they need much faster ultimately saving lives. This year alone, the Civil Air Patrol has saved 91 lives according to the Air Force Rescue Coordination Center. Other examples are providing search & rescue, border protection, homeland security, emergency flight services, remote sensing, humanitarian support, education and training, and Air Force training support to name a few. These initial successes led Christopher Vaughan, the Geographic Information Officer of FEMA, to request the Civil Air Patrol provide GIS support for natural disaster operations. CAP remains very active fulfilling that commitment. Mr. Desmarais said that CAP took close to half a million pictures for the 2018 hurricane season. FEMA hosts all of CAP’s publicly available imagery as part of its GEOPlatform.

GIS has always been a huge part of what the Civil Air Patrol does when looking at it from a basic level of identifying locations, features, and information. Now, GIS is becoming central to the operations of the Civil Air Patrol because it is a force multiplier as in the example above, using spatial intelligence for completing disaster estimates in days instead of weeks with a fraction of the staff. This is powerful and driving the future of CAP towards a more geocentric operation. CAP’s GIS future is in modeling, remote sensing, crowdsourcing, artificial spatial intelligence, and data sharing.
In 2019, the Civil Air Patrol proposed its path forward creating opportunities for its members to gain valuable GIS skills and creating a qualification in GIS Operations. The Civil Air Patrol has recently begun fielding courses with support from its partners to provide training qualifications. Members of CAP can receive the following training courses: GIS for Emergency Managers, GIS Applications for Emergency Management, GIS Specialist and training in HAZUS, a GIS-based hazard analysis tool. This requirement for operations to become geocentric is so great that a call went out for people who are doing GIS work to reach out to the Civil Air Patrol Wing in their local area and consider joining. To find out more get in touch with your local Wing, visit www.GoCivilAirPatrol.com and enter your zip code to find a CAP squadron near you or you can reach out to the CAP National GIS team at [email protected] for more information. The Civil Air Patrol is using GIS more every day for search and rescue operations where CAP members are locating aircraft crash sites using ADS-B and radar data, and locating missing persons using cell phone forensics, and creating situational awareness maps for tracking resources and planning purposes for CAP senior leaders.
The Civil Air Patrol is investing into autonomous aircraft technologies. It has the largest inventory of small unmanned aerial systems (sUAS) for civilian/ public safety use in the nation. The great advantages to CAP for sUAS are their low costs to deploy and their ability to collect close-up, high-resolutions imagery with minimal risk to people. In disaster areas flying low level flights are extremely hazardous to piloted aircraft because wires and cables and other smaller objects that have shifted. The use of sUAS will fly alongside emergency responders and CAP expects to have sUAS available for each of its 150 incident command posts across the country by the end of 2020 with over 1,000 trained operators nationwide.
In the future, the high-resolution 3D imagery point clouds will enable the Civil Air Patrol to provide real-time virtual environments and augmented reality enhanced awareness for humanitarian assistance and disaster relief operations, especially when that imagery is infused with powerful geographic information systems and artificial spatial intelligence algorithms.
In the near term, the Civil Air Patrol will be expanding the number of aircraft it has equipped with FLIR and other high-end sensors and will continue growing its sUAS operations. It will continue its outreach efforts to build working relationships with new partners and bring onboard volunteers interested in supporting GIS and imagery analysis.
As technology evolves, the Civil Air Patrol will continue to be a platform for implementing new technologies to secure the country in times of crisis. The words spoken by Colonel Scott at the First Report to Congress in May 1948 continue to ring true.
“I predict that the Civil Air Patrol will grow immeasurably stronger — it will continue to contribute to the strength and the security of this nation.” —Colonel Scott, First Report to Congress, May 1948

Advancements in sensors, cameras and automation have fueled the growth of the aerial imaging industry, which is expected to reach $2.83 billion by 2022.
By Swamini Kulkarni
Unmanned aerial vehicles (UAV), or drones, often gain the spotlight with to their ability to capture the view from a vantage point. For years, airborne cameras have clicked never-seen-before pictures across planet. Now imaging technology is utilized to monitor natural calamities and borders of countries.
Drones have been quickly adopted in various industries including surveillance, geospatial mapping, post-disaster monitoring, and even entertainment. The advancements in sensors, cameras and automation have fueled growth of the aerial imaging industry.
Cameras mounted on balloons, kites and now drones are used widely across various verticals such as government, agriculture, civil engineering and research. Surveillance through satellite imagery has challenges, many of which drones can overcome. Drones can be used whenever we want and can be equipped with lidar systems, geographic information systems and advanced cameras. This has created lucrative opportunities in the aerial imaging industry.
According to Allied Market Research, the global aerial imaging market is expected to reach $2.83 billion by 2022, growing at a CAGR of 12.9% from 2016 to 2022. The launch of novel and intuitive cameras has further increased the popularity of aerial imaging.
Advent of novel, intuitive cameras for aerial imaging
AirSelfie, a prime market player in the aerial imaging industry, launched AIR PIX aerial camera at Consumer Technology Association (CES) 2020. The company announced that it has started shipping AIR PIX+ to customers the world’s smallest pocket-sized aerial camera. Moreover, it declared that it would make available AIR DUO, the aerial camera equipped with the dual parallel camera later in 2020. Both of these cameras offer state-of-the-art technology and would prove to be vital in aerial imaging and capturing videos from the air.
Skydio, the leading U.S. manufacturer of drones and autonomous flight technology, recently launched new software solutions and autonomous drone platform for situational awareness and inspection. It is observed that despite the potential drones showcase in aerial imaging, its adoption is still limited due to concerns regarding the risk of crashes of autonomous drones.
Moreover, the requirement to hire experienced pilots and data security concerns prevent firms from scaling their aerial imaging programs. That’s why Skydio aims to unlock the potential through this autonomy software and change people’s perspective toward drones.
In addition, the company has partnered with Eagleview, a leader in aerial imagery industry and data analytics to empower home insurance agents to offer accurate inspection of residential homes without the use of expert drone pilots. This technology is expected to be available in the fourth quarter of 2020.
Artificial intelligence: Future of aerial imaging
Today, every industry is searching for ways to operate devices remotely or at least with minimum physical contact. With the experience of global pandemic keeping in mind, the future is clearly bright for autonomous drones.
Several industries, including aerial imaging, rely on advancements in autonomous UAVs. Moreover, the success of aerial imaging depends on both autonomous drones and carefully dealing with the data gathered by aerial cameras. This is where artificial intelligence (AI) comes into the picture.
For use of aerial imaging for property surveillance, there is a dire need for a solution that can streamline data analysis, make sense of the data gathered by cameras, and scale up the level of details offered by aerial imaging.
AI-based aerial imaging can be used for automated property analytics and streamline facilitation of risk underwriting and claim management. Moreover, it can offer datasets to improve risk modeling. AI-powered aerial imaging technology can leverage AI to detect changes in property evaluation, which can benefit public safety and city planning.
COVID-19 increases data demand
We live during a period of drastic change. The COVID-19 pandemic has influenced almost every industry across the globe and has increased the demand for quality of data despite a lack of resources. Moreover, there is a need for faster and better data analysis to help industries scale up. The incorporation of AI and aerial imaging can benefit organizations to scale up their operations and streamline their processes at affordable costs.
Nearmap, a prominent aerial imagery company, has launched its innovative Nearmap AI for automatic aerial imagery insights at scale. This technology is the first among aerial imagery to offer AI analysis along with high-definition aerial images on a commercial scale. Moreover, it enables customers to automatically detect ground features and verify insight against aerial imagery at a larger scale.
It is clear that the use of aerial imaging will increase in the future. Moreover, the integration of AI in aerial imaging will help organizations to scale up their business and aid in data analysis to gain valuable insights.
It is safe to say that the aerial imaging technology has changed over time, but the desire of humans to see the world from a high above has been constant, which is exactly what should keep aerial imaging technology profitable in years to come.
Allied Market Research is offering a market report on aerial imaging.

A point cloud is fundamentally a simple construct. It is a collection of points in 3D space, each point being given a coordinate in Cartesian convention. The points can also be given other properties, often these will be indicative of how they were obtained.
Examples might include the time at which they were “seen” by the surveying device that collected the data. The intensity or error in position that the point has might also be included.
Often point clouds will have around 100 million points after conducting a survey. Photography can also be overlaid on point clouds using photogrammetry techniques to essentially build 3D photography.

INS survey: point clouds
The principal method of collecting point-cloud data is by using lidar. Lidar technology is akin to radar: light is sent out from the device and bounces back off of objects. The difference is that radio uses large wavelength radio waves and lidar uses small wavelength lasers for high precision.
The time for light to return to the device is used with the speed of light to calculate the distance away. Typically, a lidar device will contain lasers with a fixed vertical angle, but which spin around in the horizontal plane. Internally, the device knows at what angle the laser is pointing vertically and its azimuth angle. This gives the device the position of the point on the object in 3D spherical coordinates.
The lasers inside produce thousands of points per second. Intensity, mentioned above, refers to the intensity of the reflected beam and indicates the reflectivity of the object.
What is a georeferenced point cloud?
Lidar requires navigation data to conduct a survey. We combine the navigation data with the lidar data to create georeferenced point clouds. Lidar devices know where points are in relation to each other, but they need to be told where they are in the world to be able to build a point cloud while moving the lidar.
The navigation data often comes from an inertial navigation system (INS). An INS is a sophisticated combiner of inertial measurement unit (IMU) and GNSS data to get the best navigation data — so a device knows where it is in the world and how it is moving.
The coordinates from the INS are added vectorially to the point coordinates of the lidar to get the final coordinates that would be used in the point cloud. This allows a user to put their lidar device on a vehicle like a van or an unmanned aerial vehicle (UAV) with an INS, to survey large areas efficiently instead of doing multiple static surveys and stitching them together.

What are point clouds used for?
There are a wide range of applications for which point clouds can be used. They are increasingly used in real time for robots and autonomous driving computers to understand their environment and navigate through it. The data in a point clouds is convenient for recognizing and identifying surfaces and objects; for example, other cars, road signs and lane markings.
OxTS has been a global leader in inertial and GNSS technologies since 1998. OxTS is fundamentally involved in helping car manufacturers get the navigation data they require to go with lidar data in autonomous vehicle development, and in point clouds creation for use in surveying.
Distances and volumes are easy to calculate using point-cloud analysis software, and intensity can help identify different materials.
Another feature that lidar offers is multi-returns. This allows a laser pulse (which has a finite cross-section) to bounce back off of multiple surfaces to give multiple points from the same pulse. This is particularly useful for seeing windows and also seeing through them, and also for a myriad of other uses such as seeing the top of a treeline and the ground when flying over with a UAV.
It can also be used to see snow depth. The lidar can see the top layer of snow and also gets another strong return from the ground beneath.
At OxTS, we see lidar point clouds being used for driverless-car and work-vehicle development, coastal and forest management, infrastructure monitoring (signs, drains, bridges, road surfaces, railroads, etc.), creating 3D models of cities, pipeline exploration and more.
The final product is a simple file format, for which the possibilities are almost endless — and we see new applications using point clouds all the time.
