How to Separate out the disconnected regions of a raster into independent rasters?

ShaunakVairagare

Please refer to the attached image. The overlay on the map shows a raster file with disconnected circles. I want to split each of those circles into independent rasters in one shot. Is that even possible? If yes how? If not whats the fastest way to do it (avoiding as much donkey work as possible)?

If in ArcGIS 10, you can use the Iterators in model builder to clip out the raster with each region. If you already have a polygon feature for these regions, you can use it. If not, Reclassify your raster to a single value and convert it to polygons using Raster to Polygon. You can then use model builder and insert > iterators > Iterate feature selection. Add Clip raster tool into model and use iterated feature as output extent. For clip tool, check the option to �??use input feature for clipping geometry�?�
