Raster I/O Simplification. A set of python modules which makes it easy to write raster processing code in Python. Built on top of GDAL, it handles the details of opening and closing files, checking alignment of projection and raster grid, stepping through the raster in small blocks, etc., allowing the programmer to concentrate on the processing involved. RIOS was written for our own use, and comes without any warranty, or assurance that it might even be useful, but if anyone else is silly enough to want it, they are welcome to it. It is licensed under GPL 3, as given in the file LICENSE.txt.
