I am trying to clip a raster by shapefile perimeter using the Clip tool. The percentage has been jumping between 0% and 100% for over an hour, back and forth, climbing to 100% then dropping down to 35% or so all over again. Does anyone know how to fix this? I'm desperately trying to cut down this raster file so I can continue doing my work, since it has to re-draw the entire raster every time I add a point to a point shapefile. Arg!

I'm using ArcGIS10 with SP4 installed. This occurred in ArcMap while running the Clip tool under Data Management Tools > Raster > Raster Processing > Clip.

Thanks.

Rachel, please take some time to read through the faq and then reformulate your question. It's nearly impossible to answer your question without even knowing what program/version you're using. –  unicoletti Mar 19 '12 at 6:01
    
Sorry about that. They did end up working, but the error occured the entire time and I had no sense of how close it was to done. I'm using ArcGIS10 with SP4 installed.

An easier workaround may be to calculate pyramids. Then ArcGIS will be able to quickly render the image at a variety of scales. You can do this in the catalog: right-click raster > Build Pyramids... –  Aaron Jun 24 at 20:08

The progress bar only appears to be jumping up and down. What is actually happening is that the geoprocessing tool has an individual percentage/progress bar for each of its subset calculations. A subset calculation will complete at 100% and then a new calculation will begin at 0%.

ArcGIS does not always inform you that this is happening, and when it happens with a lot of subset calculations in a short time period, it does appear to be jumping back and forth.

One window that you can pull up that might bring more insight into the calculation is the Geoprocessing Results window. You can access this window during the calcuation by clicking Geoprocessing on the drop down window then selecting Results:
