Hello all.<br><br> I downloaded some geoid data from <a href="ftp://topex.ucsd.edu/pub/global_geoid_2min/" target="_blank">ftp://topex.ucsd.edu/pub/global_geoid_2min/</a><br>there are three files:<br><br><a href="ftp://topex.ucsd.edu/pub/global_geoid_2min/geoid.egm96.grd" target="_blank">geoid.egm96.grd</a><br>
<a href="ftp://topex.ucsd.edu/pub/global_geoid_2min/geoid.img.9.2" target="_blank">geoid.img.9.2</a><br><a href="ftp://topex.ucsd.edu/pub/global_geoid_2min/geoid.img.9.2.ers" target="_blank">geoid.img.9.2.ers</a><br><br>
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:<br>
<br>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 <br><br>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)<br>
<br>Anyone have used this data?<br><br>cheers<br><br>Carlos<br clear="all"><br>-- <br>+-----------------------------------------------------------+<br> Carlos Henrique Grohmann - Guano <br> Geologist M.Sc - Doctorate Student at IGc-USP - Brazil<br>
