The pilot was a success and provided many recommendations to DHS and the DC Government regarding how geospatial intelligence can be shared among multiple jurisdictions to accomplish long-term and large-scale emergency management goals.

NLT provided GIS services including GIS analysis, simulation, visualization, and cartographic production. NLT was responsible for the development of pilot applications addressing spatial situational awareness, pilot support for Homeland Security emergency response, hazard mapping and analysis, as well as spatial crime analysis.
One of the projects involved suspicious financial activity analysis, in which NLT’s GIS analysts geocoded over 300,000 suspicious activity reports, identifying links between suspicious locations and distances travelled to commit a crime. Another project involved foreign student visa analysis. Using the Student and Exchange Visitor Information System (SEVIS) visa data, NLT analyzed the density of foreign students in major cities.
Another project involved gang activity analysis, in which NLT geocoded a list of suspected gang members by gang affiliation and analyzed the points based on county and census tract density. The final project involved radar terrain masking data analysis. For this project, NLT’s GIS analysts used surveillance data to geospatially analyze 25-plus drug smuggling cases along the U.S-Canada border.
Among the factors covered were aircraft takeoff and landing points, terrain models, and radar coverage overlays. Final products included PDF maps and KML file exports for ease of distribution.
