Aerial Mapping Fall 2012

Aerial Perspective

Privacy & UAS

Two issues-privacy and UAS (unmanned aerial systems)-will have a more profound impact on the ability of aerial mapping firms to operate in the U.S. market in the coming months than any technology change experienced in the past 20 years.
     While the advent of digital aerial sensors, GPS, IMUs, lidar and other technological advancements have revolutionized aerial mapping in recent years, firms engaged in the aerial mapping profession are now confronting a serious threat and potential opportunity.  And the two are not unrelated.
    In March 2012, the Federal Trade Commission (FTC) issued a final report, "Protecting Consumer Privacy in an Era of Rapid Change" providing recommended actions for businesses and policy makers to protect consumers' private information.  The report seeks to regulate the collection, sharing, or use of "precise geolocation data" about a citizen, requiring the "affirmative express consent" or advance approval of each such citizen.
     While FTC had previously indicated that a definition of the term "precise geolocation data" or an exception for the legal, legitimate, and ordinary activities in the professional geospatial practice would be included in the Commission's final report, no such exemption or clarification was included.  The Coalition of Geospatial Organizations (COGO) has appealed to the Chariman of the FTC for such an exclusion.
     "The revisions, additions and clarifications COGO has suggested would provide clarity with respect to parcels and addresses," said Jeff Lovin "Woolpert, Inc., Dayton, OH), MAPPS Delegate to COGO, who originated the letter.  "One footnote in a 122-age report does not go far enough to protect areas of professional services that have not been identified as a problem or pose any privacy concern to citizens."
     Privacy invasion by UAS has also caught the attention of Congress.
     Presently, only government and certain government-sanctioned entities can fly unmanned vehicles in the national airspace of the United States.
     That changed on February 14, 2012, when President Obama signed Public Law 112-95, the Federal Aviation Administration (FAA) Modernization and Reform Act of 2012.  This new law instructs the FAA to release a proposed rule that will establish policies, procedures, and standards for a wide spectrum of users in the small civil, commercial, unmanned aerial system UAS community.  That will include aerial imagery and aerial survey data collection operations.
     Speaking at the MAPPS summer conference in Snowmass, CO in July, Randy Willis, acting air traffic manager in the FAA's UAS Integration office, said proposed regulations will "enable small UAS to perate safely in limited portions of the NAS and gather data."  He said rules will enable the widest range of activity that can be safely conducted within the shortest rulemaking timeframe.  A Notice of Proposed Rulemaking will be release later this year.
     As government use of UAS transitions from military operations overseas to domestic uses by civil agencies, concerns for the privacy of U.S. citizens have grown.  Several legislative proposals have been introduced in Congress to restrict UAV surveillance by government agencies or contractors.  One such bill, stating, "a person or entity acting under the authority of the United States shall not use a drone to gather evidence or other information pertaining to criminal conduct or conduct in violation of a regulation except to the extent authorized in a warrant" could affect crop monitoring, pollution, and other activities for which conventional aerial photography is now used.  Such manned aerial surveillance and enforcement was upheld as constitutional by the Supremce Court in Dow Chemical Co v United States (476 U.S. 227 (1986)).
     In its 1986 decision, the court found, "It may well be, as the Government concedes, that surveillance of private proerty by using highly sophisticated surveillance equipment not generally available to the public, such as satellite technology might be constitutionally proscribed absent a warrant.  But the photographs here are not so revealing of intimate details as to raise constitutional concerns.  Although they undoubtedly give EPA more detailed information than naked-eye views, they remain limited to an outline of the facility's buildings and equipment.  The mere fact that human vision is enhanced somewhat, at least to the degree here, does not give rise to constitutional problems."
     Since that time, commercial remote sensing satellites have entered the market and such imagery is generally available to the public."  Absent new legislation, the availability of imagery from a UAS and its use by a government agency or its private contractor (as was the case in Dow), may ultimately be settled in court.

Aerial Mapping Spring 2012

Editor's Desk

Welcome to the spring 2012 edition of Aerial Mapping, the seventh year for this publication.

“Spring edition?” you may wonder. Yes, demand for
Professional Surveyor Magazine’s Aerial Mapping special has exploded, and we will be introducing our now bi-annual edition this fall. We are currently soliciting articles for this fall issue and also welcome topics to cover in PSM’s very popular Aerial Perspectives column.

Check out this edition’s informative, technical articles on topics ranging from image acquisition and internet distribution by Surdex, to Wilson & Company’s historic watershed mapping for the Albuquerque USACE, to Geo-Cue’s advanced data dissemination techniques employed by the NGS. You will also find an account of the USDA Agriculture Research Service’s use of UAVs to obtain high-resolution sensing for range management.

I always enjoy catching up with my colleagues by reading the interesting case studies and company profiles here, which continually evolve to reflect the demands of the marketplace.

While 2011 was a flat continuation of The Great Recession, the outlook for 2012 in the aerial mapping world appears improved.

Many smaller firms are surviving on a fraction of their pre-recession volume. I touched base with my friend, Gerrie DeGross, PLS, proprietor of DeGross Aerial Mapping in Bothell, Washington. Gerrie and his son Mark are working principals and now the sole remaining employees in their tiny photogrammetry shop that Gerrie founded in 1984. He said that his volume of business dropped by half each year from 2008 through 2010 but leveled off in 2011.

On a more optimistic note, some bigger firms with broader service offerings and diverse client bases report that they are not only surviving but prospering. Pat Olson, CP, PE, PLS, president of AeroMetric, a national firm with a staff of about 240, told me that his company “achieved a near-record volume in 2011, and we are confident that we will surpass that in 2012 by a substantial margin.” He said he is seeing increasing opportunities in 2012 in the sectors of transportation, environmental remediation, and energy (including possible mapping for the controversial Keystone pipeline corridor). Pat added that “lidar is red-hot for transportation,” so his firm just acquired their third lidar sensor.

Whatever the size of your business, I know you will give 2012 your best effort, and I wish you all success. Drop me a line to let me know how you are doing, even with some suggestions on ways we can grow as a profession.

Now, surveyors can remotely and safely measure large,
difficult-to-reach or dangerous areas.

With the commercialization of its drone only last year, Gatewing is already one of the leading companies in the design of unmanned aerial vehicles for mapping and surveying. Based on the revolutionary X100 lightweight aircraft, Gatewing built a remote sensing solution that consists of image acquisition field operation and fully automated image processing.

With the Gatewing X100, the gap between traditional terrestrial surveying and conventional photogrammetry has finally been filled. Now, surveyors can remotely and safely measure large, difficult-to-reach or dangerous areas. For photogrammetrists, smaller projects suddenly become highly cost-effective.

Image acquisition is conducted using the X100 – a light, unmanned aircraft with an on-board, high quality calibrated camera which captures images with a resolutionof 5 cm when flying at a default altitude of 150 m.
One of the strengths of the system is that flights are conducted in a fully automated manner, from launch to landing. Simply plan the area that needs to be scanned based on the easy-to-use softwarewizard, launch the device and let the X100 cover the pre-defined area. Through parallel sweeps the aircraft takes high- quality pictures with a high overlap.

For the creation of orthophotos or digital surface models, Gatewing offers StretchoutTM, a highly automated software package that converts your raw X100 image data set with just a couple of clicks. The quality of the results is outstanding! Razorsharp, no artefacts, intense colors, and above all the spatial accuracy which makes it a true surveying tool.

Correlator3D produces dense digital surface models (DSM), digital terrain models (DTM), orthomosaics and vectorized 3D features.

Utilizing the latest in advanced computer vision technology, SimActive developed patented algorithms for the generation of highly accurate dense DSMs. Featuring the world’s only GPU-powered DSM technology, Correlator3D supports rapid production of large datasets.

The DSM can then be used to extract a DTM. In this process, unique algorithms are used to automatically detect the ground and generate a bare earth model. Interactive monoscopic editing tools can then be used to further enhance the DTM.

Using the DTM as an input, Correlator3D handles the generation of thousands of orthophotos. True orthos can also be created. Fully automated seamline generation algorithms then stitch the orthophotos together to form a seamless mosaic. Advanced color balancing algorithms ensure radiometric integrity. 

To edit automatically generated seamlines, an interactive visual interface is  used with real-time updating of the final mosaic. This interface was designed to interact smoothly even with large datasets, saving users time with such operations as zooming and panning.

A further application of the DSM is found in extracting vectors. Correlator3D features an innovative semi-automatic approach for extracting 3D vectors in a highly intuitive 2D interface. Real-time feedback and analysis aids users as 3D vectors are created.

Correlator3D offers a complete photogrammetric workflow designed for large scale production environments.
