[Gdal-dev] coord system in form of TIFFTAG - value

[Gennady Khokhorin]

Hello, all.
Can not find in docs or src code: is it possible to get Coordinate System 
info in form of TIFFTAG, value?

Ex. 1024 = 1, which translated from GTModelTypeGeoKey  =  ModelTypeProjected
or 3072 = 32606, which is ProjectedCSTypeGeoKey = PCS_WGS84_UTM_zone_6N.

Thanks in advance.
