How to test raster formats

Raster formats are best tested by creating different sample raster process definitions (.RPDefs) that access the various forms of formats to be supported. The .RPDefs can be created using a simple affine transform to place the raster in a know location. Ensure that the full spectrum of sizes (in rows and columns), band combinations, and so on, are included as samples. The .RPDefs can then be added to a service that is published and then should be accessed by multiple clients simultaneously.  During the test, comparisons in the speed of access should be made against similar raster formats to check the efficiency.
