I'm upgrading a python script so that it'll function in ArcGIS 10.1 and as such I have the opportunity to change the raster format. Currently, the rasters are saved in Esri's grid format which has a few drawbacks. The most notable one is that grids cannot be stored in a directory structure with more than 120 characters (including the name of the raster). I believe this is no longer the case starting with 10.0; is this true?
Also, what is the most efficient raster format when using Spatial Analyst? Is it Esri's Grid, Erdas' IMG, or storing them in a file geodatabase? Efficiency, I'm defining here as the fastest processing time but I'm also concern to a lesser degree with storage size.
The output from these steps will be single-band and either integer or float.
