I am trying to write a script that does the following.
- Imports an xls file containing x, y, and other columns with data. I want to make this into a point shape file.
- I want to take that point shapefile and do a sum of two columns and the result be outputted to an additional field within the point shapefile.
- Lastly I want to take that modified shapefile and do an IDW and output a raster.
I have tried the first step but no luck so far. Anyone has any good comments I could feed from?
