CSISS (Center for Spatial Information Science and Systems) and GMU (George Mason University) offer almost 80 APIs that provide geospatial processing and analysis services. Most of these APIs are based on GRASS (Geographic Resources Analysis Support System), an open source image processing and geographic information system.
The majority of available services are for satellite image processing, raster image processing, raster map statistical analysis, and vector map processing. There are also a few miscellaneous services for tasks such as hydrological analysis and fire-spread simulation.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
