Hello.
Thanks for your answers about the comparation between Geotrans and
Proj.4. I like the identifiers and comments of Geotrans, but I'll just
use the API so the source code is not very important to me. Nevertheless
I think its better to have a clear source code.
Now I have another question about datums shifts. I have seen that Proj.4
works with lots of proyections and ellipsoids, but there are only a
few datums:
__datum_id__ __ellipse___ __definition/comments______________________________
WGS84 WGS84 towgs84=0,0,0
GGRS87 GRS80 towgs84=-199.87,74.79,246.62
Greek_Geodetic_Reference_System_1987
NAD83 GRS80 towgs84=0,0,0
North_American_Datum_1983
NAD27 clrk66 nadgrids=conus,ntv1_can.dat
North_American_Datum_1927
Does Proj.4 support other datums?
Bye
