Hi,
thanks first for all your fast answers, I'm still a bit lost in GRASS.
I'll come back to your answers to my other questions later, I have first
to work a bit more on your suggestions.
For nearly all data that I try to import with r.in.gdal, I get
warnings/error messages like this:
"A datum name wgs84 (WGS_1984) was specified without transformation
parameters. Note that the GRASS default for wgs84 is
towgs84=0.000,0.000,0.000."
or
"WARNING: No projection name! Projection parameters likely to be
meaningless.
A datum name nad83 (North_American_Datum_1983) was specified without
transformation parameters. "
or
"WARNING: No projection name! Projection parameters likely to be
meaningless.
WARNING: Datum 'unknown' not recognised by GRASS and no parameters found.
Datum transformation will not be possible using this projection
information."
I don't have any idea to what refers this "transformation parameter".
Which information is missing?
And, if I would know which information is missing and get to know it,
would there be any possibility to get this information into GRASS after
or during the import process?
Even if I can open the files ignoring these warnings, I'm struggling in
the most cases later on other operations. For example I can't project
the UTM data in LongLat (or viceversa) as Grass complains again about
missing parameters.
But my main problem is really that I don't understand with which
transformation parameters I'm dealing!
Thanks again for your help,
Martina
