[Proj] Proj and Geoitiff

[Thomas Flemming]

Hello,

does someone knows about the function GTIFGetProj4Defn from the geotiff-lib?

I have geotiff-maps from
http://www.granit.sr.unh.edu/cgi-bin/nhsearch?dset=drg/drg162
which gives no complete proj-parameters from GTIFGetProj4Defn.

Heres the output from listgeo.exe:


PCS = 32110 (name unknown)
Projection = 12830 ()
GCS: 4269/NAD83
Datum: 6269/North American Datum 1983
Ellipsoid: 7019/GRS 1980 (6378137.00,6356752.31)
Prime Meridian: 8901/Greenwich (0.000000/  0d 0' 0.00"E)
Projection Linear Units: 9003/(unknown) (1.000000m)

PROJ.4 Definition: +ellps=GRS80 +units=us-ft
