Ticket #1625 (closed defect: fixed)
problems reading etopo2v2 (arc grid, / GMT (netcdf) /HDF)

The Etopo2 data set is a 2 minute topography/bathymetry grid covering the entire world provided by NGDC.
Version 2 of this grid comes in several different formats: I have tried to import them using the GDAL library, and it does not seem to work.
I have also tried to import the grids using the GW tools (file->import) but i seems to crash the program.
This is what happens: GMT: poDataset->GetRasterXSize(); poDataset->GetRasterYSize(); poDataset->GetRasterCount?(); returns wrong values.
ARC, and HDF does not have the same problem. The values returned from the GDALDataset seem to be correct, but when i try to read the array using poDataset->RasterIO(...) it does not work, it returns errors.
Do anyone else have the same problem with these grids?
