Subject : NCAR cgm and PV-WAVE
Has anyone out there figured out a way to read an NCAR graphics CGM file
into PV-WAVE ?, or else to use NCAR graphics (v.3.0) CTRANS > to display
a PV-WAVE produced CGM file.
The issue is to combine a PV-WAVE image with a graphic overlay (geographic,
boundaries, grid etc).
In this context, has anyone written PV-WAVE, IDL utilities that display
geographic data, (eg, CIA World Data Bank) data.
Thanks Axel

An NCAR CGM has *extra stuff* stored in the first 32 bits of each record, therefore, if you stripped these out, the CGM is (in theory) readable by any CGM interpreter. NCAR Version 3.00 has a utility that does this, ncar2cgm, that converts an NCAR CGM to "vanilla" CGM format. cgm2ncar does the opposite. Hope this helps, ks
