NGA posts change detection RFI
On November 25, the National Geospatial-Intelligence Agency (NGA) posted a request for information (RFI) for persistent change detection and monitoring. Responses are due by 6:00 p.m. Central on December 15.
NGA requires a worldwide dataset identifying persistent changes on or near the surface of the Earth based on remote sensing imagery. NGA intends to use this dataset to provide tipping and cueing for geospatial data enrichment activities, particularly for topographic data and map production. Updated continuously, this near global dataset is primarily delivered through a web service enabled process and in a geodatabase file format upon request.
For the past several years NGA has successfully used persistent change detection data to prioritize geographic areas for topographic data enrichment. In a resource constrained environment it is necessary for NGA to drive both internal and contract production to geographic areas where changes have occurred to avoid costly and unnecessary new production where existing datasets effectively capture current conditions.
