Dear Listers,
I'm a novice in IDL, not sure if my questions are totally improper. I
want to use an Arcview format shapefile as a mask, to a huge number of
raster images, which are in a polar stereographic grid format with
separate image data files and lat/lon files. I would really appreciate
if you could give me any hint about the following questions:

1. How to read the shapefile into an IDL variable?
2. How to tailor the shapefile to my raster image grid?
3. If the above questions are not proper or impossible in IDL, would
you give me some suggestions to do the work?

Thank you in advance,
Jenny
