                Geospatial Data Management

                The Company's Geospatial Data Management solutions support civil and military Air Navigation Service Providers (ANSPs) by integrating a static Aeronautical Information System (AIS) relational database containing man-made obstacles, with a fully featured Geographic Information System (GIS) for the management and visualization of all national geographic data assets. The GIS includes multi-format vector and raster maps, orthorectified aerial photographs, and digital terrain data.

                The Company employs a Windows™-based graphical user interface and open systems architecture to support multiple versions of a static AIS database, using ESRI™ MapObjects and Oracle™ as the embedded GIS toolkit and relational database, respectively.

                Functionally, ?the Company's solutions integrate a data exchange module to provide built-in data import and export compatibility with a wide range of cartographic and aeronautical data standards that include DAFIF, DVOF, Aeronautical Radio Incorporated (ARINC) 424, aeronautical information exchange models (AIXM), DTED, DEM, CADRG, TIFF, and VPF.

                Import and export mechanisms include extensible mark-up language (XML), delimited text files, SQL, and ODBC, allowing data ingest from widely available sources and legacy databases, and the electronic export of data in formats to other systems, without the need for manual intervention. Using configurable security privileges and geographically defined workspaces, these solutions enable division of responsibility for national data asset management among multiple data specialists, with a full audit trail capability that logs the time/date, user ID, and nature of every modification made to the datasets.
