Hi all
I have Location/Mapset with this characteristics:
g.region -p
projection: 3 (Latitude-Longitude)
zone: 0
datum: wgs84
ellipsoid: wgs84
I'm I'm trying to import a file with the following geographic
characteristics (using gdalinfo):
Driver: GTiff/GeoTIFF
Files: euro_area_latlong.tif
Size is 1721, 595
Coordinate System is:
GEOGCS["WGS 84",
DATUM["unknown",
SPHEROID["unnamed",6378137,298.2572235629972]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433]]
When I do r.in.gdal, to import this file, I get the following Warning:
Datum <unknown> not recognised by GRASS and no parameters found
Projection of input dataset and current location appear to match
please post the output of
gdalinfo euro_area_latlong.tif
It imports but it wasn't suppose to get this error since i'm using the same
coordinate/projection system. How can I avoid this? Should I add more
information to destination_projection when I warped that file?
Either the metadata in euro_area_latlong.tif are read correctly by GDAL or
a definition is missing or the metadata are incorrect in the file. From the
gdalinfo output we may understand more...
