Hi,
I've downloaded srtm_41_19 both in tiff and ASCII formats.
I reproject the tiif image such:
gdalwarp -t_srs '+proj=tmerc +lat_0=0 +lon_0=21 +k=1 +x_0=0 +y_0=0
+ellps=WGS84 +datum=WGS84 +units=m +no_defs' srtm_41_19.tif srtm_lo21.tif
and gdalinfo produces realistic values.
But the software I want to use this tif-DEM in complains:
Error encountered while reading GeoTIFF file: Elevation data must
be specified as 32-bit floating point samples.
Hi Zoltan,
you can add "-ot Float32" to your gdalwarp command to produce a 32-bit
floating point file (which your software seems to want).
Best,
Vincent.
The software however does read the ASCII version, but I need to
re-project the ASCII file to Lo19 (see above proj string).
How can I do this?
Thanks & regards,
Zoltan
