Sanborn gathers drone imagery of Denver golf courses

The City of Denver has contracted with the Sanborn Map Company Inc. to collect high-resolution, full-motion video imagery of the city’s seven public golf courses and its Aqua Golf facility.

Sanborn employs a commercial-grade unmanned aircraft system (UAS) from Denver-based Leptron Unmanned Aircraft Systems. The UAS is capable of producing unprecedented accuracy and resolution, including high-quality, engineering-grade digital terrain models exceeding 2-inch accuracy; multispectral frame imagery at sub-centimeter resolution; and crisp, vibration-free video. Earlier this year, the Federal Aviation Administration granted Sanborn a Section 333 Exemption, which permits the firm to offer commercial UAS services nationwide.

“We launched our new golf website earlier this year and now we look forward to adding the Sanborn imagery,” said Leslie Wright, Denver Golf director of marketing. “Our course locations range from densely populated urban areas to mountainous terrain with elevations above 7,000 feet. We also had a very tight window in which to perform the work. Considering these diverse challenges, Sanborn has approached the project with a high degree of professionalism and has been great to work with.”

The city will use the images for marketing, as well as to give golfers a bird’s-eye view of every hole with realistic fly-overs down each fairway from the tee box to the green. The city’s Overland Park Golf Course is the oldest operating course west of the Mississippi River, according to a news release from Sanborn.

“Sanborn’s UAS technology is a great fit for a host of customers,” said Sanchit Agarwal, director of mapping operations. “Among them are police and fire departments, agricultural operations, utilities, oil and gas concerns, emergency response managers, local government, mine operators and the media.”

Sanborn acquired this bird’s-eye view video of the 17th hole at Denver’s Evergreen Golf Course with its commercial-grade UAV.

Bentley Systems offers new sewer and stormwater products
StormCAD from within OpenRoads.

Bentley Systems’ latest infrastructure products are now available. They include SewerGEMS, SewerCAD, StormCAD and CivilStorm V8i (SELECTseries 5) products for the analysis and design of wastewater and stormwater systems. All of the V8i (SELECTseries 5) sewer and stormwater products can be used as stand-alone products, or be run on CAD and GIS platforms.

They can also now be used from within the V8i (SELECTseries 4) versions of OpenRoads-based products — combining 3D design and hydraulic analysis capabilities in the same platform. The resulting comprehensive civil solution eliminates the need for extra import/export steps or file conversions, Bentley Systems said.

“The integration of Bentley’s OpenRoads civil design functionality with the advanced capabilities of Bentley’s storm and sewer analysis products will be a huge benefit to productivity and quality for our highway drainage design workflows,” said Chris Haines, senior civil engineer and PAR-BIM technical lead, Drainage and Utilities, Parsons.

“With these new releases, the automated hydraulic design functionality of our sewer and storm products can be effortlessly combined with the 3D physical design and terrain modeling capabilities of Bentley’s other civil products,” said Gregg Herrin, Bentley Systems director of product management, hydraulics and hydrology. “From an information mobility standpoint, this has a direct and substantial positive impact on roadway, site and municipal work where hydraulic engineering is just one part of a much larger project.”

Bentley’s SewerGEMS, SewerCAD, StormCAD and CivilStorm V8i (SELECTseries 5) products provide the following capabilities:
- Ground elevations from terrain models may be used during automated design runs to consider “cover” along a pipe’s length, improving decision making related to system design.
- Terrain model elevations can also now be added to profiles, improving the resulting visualization and the user’s understanding of the physical network.
- New low-impact development (LID) elements are now available, making it easier to model a wider range of controls for stormwater management.
- With the new lateral link element, engineers can include lateral pipes in their hydraulic analysis without creating “fake” elements where the laterals connect to the main pipe.
- Easy access to the Bentley Communities professional networking site is embedded within the applications, facilitating communications between users and Bentley’s hydraulic modeling experts.
Users of any of these SELECTseries 5 releases now benefit from the products’ support of MicroStation V8i (SELECTseries 3), OpenRoads V8i (SELECTseries 4), AutoCAD 2015 and 2016, and ArcGIS 10.2 and 10.3 (SewerGEMS only), giving them the ability to model from within the latest MicroStation, OpenRoads, AutoCAD or ArcGIS version.

Open Geospatial Consortium Seeks Participants for Elevation-Data Experiment
The Open Geospatial Consortium (OGC) announces a Call for Participation in the OGC GeoPackage Elevation Extension Interoperability Experiment (GPKG-EE IE).

The OGC GeoPackage Standards Working Group (SWG) has identified a need to store tiled gridded elevation data in a GeoPackage. GeoPackage is an open, standards-based, platform-independent, portable, self-describing, compact format for transferring geospatial information. The SWG has developed a candidate extension to the GeoPackage Encoding Standard to support elevation data.

This capability will be used to support use cases such as the following:
- Visualization
  - 2D (hillshade, color relief, slope)
  - 3D (supporting changing view angles and level of detail)
- Analysis
  - Viewshed and line-of-sight
  - Cross-country mobility (off-road routing)
  - Site suitability and planning (slope analysis such as helicopter landing zones)
  - 3D geometry representations of features (ground-based, airspace)
  - Terrain association (associating images to mapped locations)
  - Augmented reality based training
The SWG proposes validating the extension by running an Open Geospatial Consortium Interoperability Experiment. An OGC Interoperability Experiment is a rapid, low overhead, formally structured OGC-facilitated activity in which members achieve specific technical objectives that further the OGC Standards Baseline. The GPKG-EE IE will test and refine the elevation extension. To do this, the SWG needs the international support and acceptance of a globally representative community that provides both domain and technical expertise to this project. While the OGC is a member-driven organization and the SWG needs a core of OGC members to support and initiate this work, non-members can participate as “observers.”

The GPKG-EE IE will perform the following experiments:
- Experiment #1: produce GeoPackages containing tiled gridded elevation data in accordance with the proposed extension.
- Experiment #2: use the GeoPackages to perform visualization and/or analysis operations as described above.
The results of the Interoperability Experiment will be documented in an OGC Engineering Report. In addition to the Engineering Report, a demonstration is tentatively scheduled for the OGC Technical Committee meeting in Washington, D.C., in March 2016.

The OGC asks interested organizations to indicate their support and commitment to be involved in this Interoperability Experiment. A summary of the activity plan, requirements for participation, schedule, and kick-off meeting details are available. Contact details are included in the activity plan.

Participants in the GPKG-EE IE, which will run until March 31, 2016, will test implementations and provide constructive comments on the exchange data model and resulting trial documentation. Experience has shown that those working in these initiatives gain valuable insights that can be used to improve existing information systems or fast-track the development of new systems. Participants gain sufficient expertise to start deploying working services for their existing data and local situations.

The following OGC members proposed the GeoPackage Elevation Extension Interoperability Experiment:
- Luciad, Belgium
- Image Matters LLC
- Compusult, Canada
- U.S. Army Geospatial Center
The OGC is an international geospatial standards consortium of more than 515 companies, government agencies, research organizations and universities participating in a consensus process to develop publicly available standards. OGC standards support interoperable solutions that “geo-enable” the Web, wireless and location-based services and mainstream IT.

A3 Edge maps wildlife in Africa

Elephants are highlighted in yellow.

VisionMap’s A3 Edge Digital Mapping System was recently used to map wildlife in an African national park. A3 Edge provides an efficient solution for detecting, tracking and estimating wildlife populations, according to maker VisionMap.

The A3 Edge camera surveyed the park from an altitude of 4,000 ft. above ground level (AGL), capturing 3.5 cm resolution imagery at a rate of 225 km²/ hour. A3 Edge uses a “sweep” capture technology that provides quick, high-resolution coverage of vast areas.

Among the animals identified in the images were antelopes, elephants, hippopotamuses and giraffes. The animals’ locations are clearly visible in the aerial images, and the automatic object recognition capability available with VisionMap systems makes it easy to calculate the number of animals in a particular area.

VisionMap’s LightSpeed processing system automatically processes VisionMap images, producing aerial triangulation, orthophoto, digital surface model (DSM), 3D models, and georeferenced vertical and oblique images. The system’s fast turnaround time makes it possible to regularly survey the area, and collect useful information about the animals’ behaviors and trends, VisionMap said.

Antelopes are highlighted in red.

GAO: Most Eighth-Grade Students Not Proficient in Geography
About three-quarters of eighth grade students — the only grade for which trend data are available — were not “proficient” in geography in 2014, according to a new analysis by the U.S. Government Accountability Office (GAO) of nationally representative data from the Department of Education.

Specifically, these students had not demonstrated solid competence in the subject, and the proficiency levels of eighth-grade students have shown no improvement since 1994 (see figure).

Geography is generally taught as part of social studies, but data show that more than half of eighth-grade teachers reported spending a small portion (10 percent or less) of their social studies instruction time on geography. Further, according to a study by an academic organization, a majority of states do not require geography courses in middle school or high school.

A key challenge to providing geography education is the increased focus on other subjects, according to officials in selected states and K-12 teachers GAO interviewed. These officials and teachers said spending time and resources on geography education is difficult due to national and state focus on the tested subjects of reading, math, and science. GAO’s interviews and review of relevant reports identified a range of other challenges, as well, including:
- misconceptions about what geography education entails;
- lack of teacher preparation and professional development in geography;
- poor quality of geography instructional materials; and
- limited use of geographic technology in the classroom.
The Department of Education’s role with respect to geography education primarily involves assessing student performance in the subject, and providing data and the results of its analyses to the public. The Department of Education periodically assesses student achievement in geography, and other areas, but not with the same regularity as other subjects it is required by law to assess. Beyond assessments, department officials said that absent funding specifically for geography-focused programs, the agency is hindered in its ability to support geography education.

GAO conducted the study because geography — the study of places and the relationship between people and their environment — is present across many facets of modern life, from tracking lost cell phones to monitoring disease outbreaks such as Ebola. The growing use of geographic information and location-based technology across multiple sectors of the American economy has prompted questions about whether K-12 students’ skills and exposure to geography are adequate for current and future workforce needs.

Senate Report 113-71 included a provision for GAO to report on the status of geography education and challenges elementary and secondary schools face in providing geography education with limited resources.

In this report, GAO examined
1. the extent that eighth grade students are proficient in geography;
2. the challenges selected school officials and teachers face in providing geography education; and
3. the role of the Department of Education with respect to geography education.
GAO reviewed relevant federal laws; analyzed nationally representative Department of Education data on student proficiency and instruction time in geography; interviewed education officials in four states selected, in part, for varying K-12 geography requirements; reviewed key studies and research reports, including a 50-state 2013 survey of geography requirements; and interviewed agency officials and researchers. The GAO also leveraged a professional association to identify and interview 10 K-12 teachers.

National Map Corps Updates Volunteer Badges

The National Map Corps has updated the recognition badges that it awards for participation in its crowdsourcing mapping project. Volunteer “citizen scientists” who collect manmade structure data such as police stations, schools, hospitals and cemeteries, to provide more precise spatial data for the USGS web-based mapping products can earn points and virtual badges.

Due to continuous project growth and popularity, TNMCorps has added more badge levels and revised the current awards. More than 160,000 points have been edited or verified to date.

The project started in 2012, and since that time, the increasing number of volunteers have verified, edited, deleted and created more than 160,000 structures points. In appreciation for the efforts of these “free” mappers, those who reach certain milestones are celebrated in the form of virtual badges.

The newly designed badges showcase the same classic surveying tools and aerial data collection methods, but have been colorfully updated and highlight a variety of amazing landscapes across the United States.

A second set of badges based on aerial data collection was introduced a year ago as some extra-energetic volunteers quickly surpassed the first set of badge levels. Currently, 11 possible badges can be earned beginning with the Order of the Surveyor’s Chain (25 points) and ending with the Squadron of Biplane Spectators (6000 + points).

As volunteer map editors attain each level, a congratulatory email is sent to the awardee with a description of the badge and encouragement to achieve the next level. With permission, volunteer accomplishments are highlighted on TNMCorps Recognition page, and The National Map Twitter (#TNMCorps).
