3dbu Posted November 29, 2013 Report Share Posted November 29, 2013 define with polygon the area that's interesting to clip and then in arcgis go to spatial analyst and look for clip by mask or what ever and clip the image....or in erdas make AOI and make clip with this area. is very easy Quote Link to comment Share on other sites More sharing options...
