I would like to collect a table of equivalent or close enough gdal based functions to replace ArcGIS functions (esp in spatial analyst). Are there functions available using gdal to perform the following ArcGIS functions:
- Zonal statistics
- Focal statistics
- Iterate through raster VAT
The key is to have a ready reckoner of such functions, so ArcGIS based code can be relatively painlessly changed to one based on gdal.
