Working with GeoRaster

Once the raster data is loaded into a GeoRaster object, the raster data is available for use by other applications. There are two main types of applications for raster data: analytical applications that use the cell values in raster data to solve a spatial or non-spatial business problem, and visualization applications that use the raster data as background images for other vector maps.

Coordinating system transformations of GeoRaster

In the sample data, we loaded rasters that are in different coordinate systems. The land cover image has an SRID of 32775 (equal-area projection) while the DEM data has an SRID of 4269 (Geodetic). The rest of the data used for our San Francisco examples has an SRID 2872. So, we first show how ...
