Trying to Clip Raster data to a simple polygon

natashaGregory-Michelman — Wed, 18 Jun 2014 01:39:48 GMT

I am trying to clip several raster datasets_individually for now_ to a simple, existing polygon in ARCMap and I am unable to see the Raster datasets in the Clip Toolset in the Geoprocessing options at all. All I see is the vector polygon....that is the one to CLIP to.

If anyone has any advice..please share.

PS: the raster datasets are overlaid and correspond to the vector data and I have built attribute tables and they all look fine. I just can't see the raster data in the CLIP tool.

I am guessing you are using the wrong clip. If you are using the Clip(analysis) then it only works with vector data. If you need to clip a raster, you need to use Clip(Data Management).

If that is not your problem, I would try the Extract by Mask, tool, you can use vector data for the mask.

Hope this helps

Check the processing extents. Sometimes, for some unknown reason, the processing extents can be changed. When this happens the results from any raster processing can be clipped to the limits of the processing extents. If that happens, you only see part of the results or no results. A telltale sign is getting no results or results that have vertical and/or horizontal limits. Puzzled me for a long time.

Go to the "Geoprocessing" menu> "Environments..." > "Processing Extent". Under Processing Extent choose a layer that you know covers the full extent of the waters you are processing and click OK.

I think the issue was more that the raster would not come up in the clip tool as a feature to be clipped, not that the clip itself was not successful.

Edit: This isn't my problem, I was trying to help

Ah... Ok.

Did the the Extract by Mask tool work? If not, try converting the tif file to another raster format.
