I have a world imagery layer that I want to clip to a single county. I would just save as a JPEG and edit using other software, but this uses a lot of processing power if I want a high resolution. I would like to clip the image before exporting to JPEG. Is this possible?

Which software are you using? If you are using QGIS, you can see this question: gis.stackexchange.com/questions/10117/… – jvangeld Mar 6 at 22:07
I am using ArcMap 10.1 – user15868 Mar 6 at 22:09

To clip the Image layer, you firstly need a polygon feature class of your area of Interest.

Once You have the data, you can 'clip' the Raster Data using Extract By Mask. This would require a Spatial Analyst License. and would give you a raster containing the data inside your polygon.

If you require a Rectangular image, centered on your Area of Interest, you could use Extract By Rectangle.

I get these errors when I try to use my image as the input. (World Imagery.lyr). I am using a county shapefile as the extent or mask data. – user15868 Mar 7 at 16:10
Don't use the .lyr file as the input. Use the actual data. – Devdatta Tengshe Mar 7 at 16:15
How would I do that? I'm a novice on GIS, so forgive my ignorance. – user15868 Mar 7 at 17:14
I am unable to open the file to access any kind of data. I can only open it with GIS, which kind of treats it as an image. There are no subfolders, etc. – user15868 Mar 7 at 17:42

If this World Imagery layer is from the 'Add Data from ArcGIS Online', then you will not be able to clip or extract as indicated in the typically correct answer by @Devdatta Tengshe. There are other ways around it but will be in violation of the Terms of Use.

That's why it won't work then. Thanks – user15868 Mar 7 at 19:05
