StarSpan - Fast algorithms for raster pixel extraction from geometry features
StarSpan was designed to bridge the raster and vector worlds of spatial analysis using fast algorithms for pixel level extraction from geometry features (points, lines, polygons). StarSpan generates databases of extracted pixel values (from one or a set of raster images), fused with the database attributes from the vector files. This allows a user to do statistical analysis of the pixel vs. attribute data in many existing packages and can greatly speed up classification training and testing.
The tool has been used in multiple projects at several research institutions worldwide, see citations according to Google Scholar.
This project was possible thanks to California State Department of Boating and Waterways. Originally located at http://starspan.projects.atlas.ca.gov, StarSpan was developed at University of California Davis Center for Spatial Technologies and Remote Sensing (CSTARS).
