Matthew, Try using Extract by Mask instead of Clip Raster. Another approach to try to is use the Extent Environment in your Resample to avoid the need to clip. ... View more

Patrick, One nice feature of GIS services is that you eliminate the download step. Its a different way of thinking about GIS but a very powerful way of doing things. Go to the content item (the ArcGIS.com webpage) for terrain and click the blue drop down box that says "Open" and the select "Open in ArcGIS for Desktop". Your browser will save a file called item.pitem to your default downloads folder. Double click that file to open in desktop. From there the service will behave just like data on your disk. You can use it as an input to Geoprocessing Tools, Model Builder, or Python Scripts. If you really want a local copy you could run the clip tool or export the data to a new raster. There is an area limit and i can't remember it right now but it should work. The 30 m Africa data was just recently released by the USGS and NGA so it should be the best available. RN ... View more

Stephanie, If you have a feature class containing multiple polygon features that you want to use as inputs to the Extract Landscape Source Data tool you can use model builder and loop through each polygon in the feature class using a Feature Selection Iterator. When you run the model it will extract and download data for each polygon in your feature class. A simple model to do this looks like this: [ATTACH=CONFIG]29065[/ATTACH] ... View more

Thanks for the help!!! I'm not sure where I went off track but the following works: import arcpy raster = r"c:\GIS_Data\some_raster" outraster = r"c:\GIS_Data\delete_me" desc = arcpy.Describe(r"c:\GIS_Data\test_extent2.shp") frame = str(desc.extent) arcpy.Clip_management (raster, frame, outraster) print "Done!" ...

Thanks for the help but I am still struggling. This script works: import arcpy raster = r"Y:\GIS_Data\raster1" outraster = r"Y:\GIS_Data\delete_me" desc = arcpy.Describe(r"Y:\GIS_Data\test_extent2.shp") frame = str(desc.extent) frame = str(frame [:-16]) frame = str('"' + frame + '"') print frame arcpy.Clip_management (raster, "-121.677618762735 42.7497214280392 -119.35205017646 45.3659860875993", outraster) print "Done!" But this one does not: import arcpy raster = r"Y:\GIS_Data\raster1" outraster = r"Y:\GIS_Data\delete_me" desc = arcpy.Describe(r"Y:\GIS_Data\test_extent2.shp") frame = str(desc.extent) frame = str(frame [:-16]) frame = str('"' + frame + '"') print frame arcpy.Clip_management (raster,frame, outraster) print "Done!" I copied and posted the output from the "print frame" statement into the clip statement to get it to work. Any ideas? ... View more
