Hello all.
I downloaded some geoid data from ftp://topex.ucsd.edu/pub/global_geoid_2min/
there are three files:
geoid.egm96.grd
geoid.img.9.2
geoid.img.9.2.ers
the grd is a GMT grid with 7.5min spacing. The other is a ERMapper image file with 2min resolution. I managed to import geoid.img.9.2 with r.in.bin:
r.in.bin -s -b input=/home/guano/geodata/TOPEX/geoid.img.9.2 output=geoid.img bytes=2 north=90 south=-90 east=0 west=360 rows=6336 cols=10800 --overwrite
but there is a shift in position. When I compare with vector data for continents limits, I see that it is shifted to north. (see attached)
Anyone have used this data?
cheers
Carlos
