This week we learned how to use Python to work with spatial data in ArcMap, specifically working with rasters. We gained experience listing available raster datasets within a specified workspace, describe properties of the datasets, utilized arcpy.sa (spatial analyst) to define raster parameters and finally wrote algebra expressions in Python.
We reclassified a raster to show only forested lands, further limited to slope 5-20 and aspect 150-270. Green in the image above does NOT meet these requirements. The purple color DOES meet all the requirements. The new raster was saved to the gdb file in our data folder. Temporary rasters for calculations were not saved.
