Visual Media Reasoning - Terrain-based Geolocation
Abstract
The ``GPU - accelerated DBMS for terrain geolocation with human perspective view verification'' project was fairly successful in achieving its capability goals. The methodologies and approaches evolved as the project was conducted, increasing the scalability of the geolocation database. A prototype web - based geolocation demonstration site wa s instantiated. The developed technologies have found other uses of interest to the greater VMR project, and some of this work continues. All of the development work for GPU - enabled geospatial data processing was completed, which includes developing GPU code for extraction of 360 degree terrain silhouettes and signature generation from the terrain. We have incorporated GPU kernels into a robust geospatial data processing application which pulls network located digital elevation data, extracts the terrain signatures, and populates a signature database. A novel technology has been developed which integrates GPU hardware with the PostgreSQL database management system to perform high - throughput pattern matching within the relational database environment.
