Summarize Raster by Polygon via OID
Posted 31 August 2010 - 12:17 PM
I am working on an analysis looking at land type throughout some different regions (52 total).
I have a raster of landcover types and I've determined a few long ways to do this analysis.
I could easily clip the raster to the bounds of all 52 regions and then summarize each clipped raster.
Ideally I'd like to do this in one fell swoop and produce a table that had the regional ID as the row and column headings that represented the landcover values. I've been trying to use Hawths tools thematic raster summary but it does not work with ARCGIS 10.
Does anyone have any suggestions as to how I can streamline this analysis.
thanks in advance,

What you get then is an attribute table with the land cover classes and the OIDs and the count of cells in each combination.

You might also try the 'Zonal Statistics' and 'Zonal Statistics as Table' tools in ArcToolbox, filed under Spatial Analyst Tools > Zonal. I'm not sure what the output tables would look like, but it might be worth a test run.
Yes, Bryan is right on. If you are using ArcGIS then the zonal statistics as table is what you want to use! Easy as pie.
