ArcGIS 10.0 – Is There a Raster Equivalent of the Split Tool?

arcgis-10.0rastersplitting

I have the DEM of a State in ERDAS Imagine (.img) format. I have a shapefile containing the counties of that state.

I want to split the whole raster into DEMs of the individual counties. The counties are irregular polygons. So this isn't as easy as splitting the Raster into tiles.

How do I split a raster with a vector polygon shapefile?

I am looking for what is basically the Raster equivalent of the Split tool.

I tried using Clip tool, and the Extract by mask tool, but both of them are unhelpful since they work only on single polygons.

I have looked at the answer given here: Need to clip raster based on field name in ArcGIS 9.3
, but Hawth Tools aren't available for ArcGIS 10.0

I have ArcGIS 10.0+ Spatial Analyst Extension, and QGIS 1.8. A solution in either will be acceptable.

This model builder workflow will extract a section of the DEM for each county polygon

enter image description here

  • Set the Group by Field variable to be County Name
  • Set the model processing extent to be the same as County
