Hello,
I have shapefiles of Indian subcontinent (i.e., .india_map.m.swp, ind_state_2000.apr, ind_state_2000.dbf, ind_state_2000.prj, ind_state_2000.sbn, ind_state_2000.sbx, ind_state_2000.shx, ind_state_2000.wmf). I don't even know what these file formats are, but inorder to draw the Indian subcontinent with exact boundary information, how I can use these files in IDL? Also, I want to include this in lat-lon coordinate box. I know how to use these shapefiles in MATLAB, but I don't have any clue in IDL.
Any help in this regard will be highly appreciable!!!
Thanks in advance,
Madhavan

There are several routines in the Coyote Library for handling shape
files. The two most useful, are cgShapeInfo for peering into a shape
file, and cgDrawShapes for drawing them in various ways. Search for
"shapefiles" on my web page for articles.
