I'm not at all clear about exactly what you're trying to do, but if I'm
guessing right, this thread may be helpful to you:
http://groups.google.com/group/comp.lang.idl-pvwave/browse_t hread/thread/4b90c8f4a2c7b715/85ec7790a493555d?lnk=gst&q =Shapefile&rnum=1#85ec7790a493555d
If the link doesn't work, try searching this newsgroup for "Apply a
shapefile to raster images in IDL."
Hope that helps,
Jeff
