I'm guessing that what you want to do is to open a MapInfo TAB file and get the
coord sys string ?
If so, you can use the Mitab library to do something like this:
#include
..."mitab_capi.h"
const char * filename = "C:\\mytab.tab"; // The path to your TAB file
mitab_handle hTAB = mitab_c_open(filename);
if (hTAB!=0)
{
const char *sCoordSys = mitab_c_get_mif_coordsys(hTAB);
// Do something with the coord sys string...
mitab_c_close(hTAB);
}
This will return a coord sys string like this:
Earth Projection 8, 12, "m", 147, 0, 0.9996, 500000, 10000000
You need to look in the MapInfo documentation to know how to decode these. In
this case its projection 8 (Transverse Mercator) , datum 12 (AGD66), units in
metres, origin of longitude = 147, origin of latitude = 0, scale factor =
0.9996, false easting = 500000 m, false northing = 10000000 m.
I hope this info helps.
Cheers,
Anthony.

Hello! I need to know a MAPINFO-collection( *.tab+*.map+ *.ind+*.id) projection
directly from this files whithout MAPINFO. It`s really? How I can do it? Thank
you!
