clipping raster data

KatherineGates — Thu, 01 Jun 2017 16:06:08 GMT

I have an aerial photo of Person County NC, then I have a Township boundary line layer. I am trying to clip the aerial photography of just on of the town ships.

So far I have tried running a definition query to only show desired township then I went to Arc Toolbox- Data Management Tools - Raster - Raster Processing - and Clip.

Then the clip window opens I select the raster aerial photo as the Input Raster and The township boundary as the Output Extent.

When I run the Clip nothing seems to happen.

Please help.

Thanks,

Check the box "Use Input Features for Clipping Geometry" in Clip tool.

I tried that once before and it did not work but this time it has been

clipping for almost 30 mins.

That's not unexpected - it can take quite a while to clip an aerial if it is a large size. Though if it takes more than several hours, then one may have to decide whether the program crashed or not....

Okay, the system has never taken this long so hopefully that is good news.

Thank you,

Also keep Background Processing (Geoprocessing Options) Disabled. Sometimes, it may cause delays/failures.

Hi Katherine,

What is the uncompressed size of the SID you are attempting to clip? You can check by right-clicking on the raster > Properties > Source tab. Another option is to create a mosaic dataset from the SID image and apply a Clip function. This takes less than a second to perform a clip compared to the Clip geoprocessing tool.
