Web-based GIS Application for Dissemination of Geodetic Data of Military Airfields
The National Geospatial-Intelligence Agency is responsible for conducting geodetic surveys of U.S. military airfields around the world. Spatial data (e.g. the position of runways, navigational aids, and obstruction features) are collected, validated, and entered into a database system. The current retrieval process does not allow immediate access to the data, which is important for air navigational safety. A web-based GIS prototype was developed to allow quick access, visualization, query, and analysis of the desired data. This web GIS prototype provides an environment that assists current and potential geodetic survey users to explore and retrieve the desired data using ArcGIS 9.3 and ArcGIS Server. This paper discusses the development and implementation of a web-based GIS prototype application which not only provides NGA with a fast and simple dissemination tool by allowing simultaneous data retrieving, but also provides NGA customers the ability to represent spatial data in its geographical context.
