Applied Economics at the National Insti- tute of Standards and Technology.The combined data lets users locate likely areas for investing in solar conversions by using the map's tools to calculate the savings over the life of the system -- based on not just the initial cost, but also operating and maintenance charges. "I think of it as math between maps," said Walker. Walker said the map will be useful for federal agencies, which have been required to obtain 20 percent of their energy usage from renewable sources by 2020. Currently, the figure is only about 7.5 per- cent. Using the ana- lytics map, Walk- er envisions that, "headquarters people are going to be looking at the map saying, 'Okay, we're go- ing to focus our efforts to identify photovoltaic proj- ects in this part of the country ... and we want our facilities to con- sider solar water heating if they're in this part of the country.' " The team is now looking to expand the map to include other renewable en- ergy sources, such as wind energy. "We have completed a wind-energy analy- sis, which we will be putting up in the next couple of weeks," Walker said. And while the solar information is on a 10-kilometer grid, the wind data is a on a 200-meter grid. "That really allows you to zoom in," he said. ARMY SITUATIONAL AWARENESS Traditionally, one of the most danger- ous jobs in the military has been scout- ing unfamiliar territory. The Army's Situational Awareness Geospatially Enabled (SAGE) project aims to reduce those dangers by giving personnel an advance look using data sets and im- agery collected from a wide array of sources. "If you are new in a country, SAGE provides you a set of products that help you understand the environment," said Dhiren Khona, principal investigator at the Army Geospatial Center's Topo- graphic Engineering Center. "It helps you understand where the slopes are, what the elevation is, and it helps you understand the mobility of your vehicle based on your vehicle's height." The tools in SAGE even allow per- sonnel to perform line-of-sight calcula- tions both on-road and off-road. "Us- ing line-of-sight calculations, you can determine where your vehicle may be exposed," said Khona. SAGE tools are implemented as a tool- box in Esri ArcGIS, the standard applica- tion for geospatial analysis in the Army. "We've developed these tools within Es- ri's framework," said Khona. "We wanted to keep the user interface simple, and the users are already familiar with the UI." SAGE is a part of the Distributed Com- mon Ground System - Army (DCGS-A), the Army's common system for intelli- gence gathering, analysis and sharing. It creates a consistent, Army-wide base- line for data ingestion and processing, as well as standardized and useable terrain analysis output for leaders, allowing more time for actual analysis. According to Khona, SAGE is used both by geospatial engineers and by in- field analysts. It does, however, require a laptop computer. No interface has yet been developed for smartphones or oth- er mobile devices. As for what data SAGE analyzes, Kho- na would say only that the tools access the National Geospatial-Intelligence Agency's Map of the World. While nei- ther Khona nor NGA would discuss spe- cific data sets available in Map of the World, it is reported to include road- ways, elevation, terrain, weather and demographic data. SAGE has been in development for four years. "Last year, we started interact- ing with units," said Khona, add- ing that the tools were used in both combat and non- combat scenari- os." According to Khona, SAGE's most recent use has been in Libe- ria, by teams responding to the Ebola crisis. Khona said the reception of SAGE by field personnel has been positive, and the Army plans to expand its deploy- ment. "We know that these tools can be used for other purposes as well," said Khona. "I think our focus over the next four years will be to expand to other market areas of the government." Khona is also looking forward to evolving SAGE into a client-server appli- cation as tactical networks become more widely deployed. "Because bandwidth can be an issue in the field, the tools themselves work on the desktop, and whenever possible the desktop is provi- sioned with the necessary data," he said. "We believe that in the future we can move into a server-based environ- ment." • GIS DATA 24 GCN NOVEMBER/DECEMBER 2014 • GCN.COM
