Hi there,
I don't seem to be able to import netCDF via r.in.gdal in grass-6.4.0RC3
osgeo4w version running on XP sp3.
GRASS 6.4.0RC3 (UTM32):C:\ >r.in.gdal input=SRF_1958.AVG.NC
output=SRF_1958.AVG location=ERA40_SRF
Warning 1: No UNIDATA NC_GLOBAL:Conventions attribute
Location <ERA40_SRF> created
ERROR: Selected band (1) does not exist
Is this something that I should be able to manage to do? GRASS complains
about bands -- the file includes georeferenced daily climate variables. The
file opens OK in viewers such as Panoply
<http://www.giss.nasa.gov/tools/panoply/>. Is there anything I am missing?
The netCDF support depends on GDAL (not on GRASS). I had limited
success so far.. Is the map in question available?
The map is 500+ MB and resides on the local server of a national lab in
Italy, so it is not available to public. It is from a set of netCDFs
including daily weather data for the Mediterranean Basin that I need to
put in text files after having removed grid points in the sea -- that is
why I needed GRASS: to find a way to mask the dataset for data on the
water that are not of interest, so as to have only data referring to
land. Each element of the netCDF array is already coded using rows and
columns of the grid, so I wanted GRASS to tell me which elements
(referring to sea) to remove from the dataset and which to retain (those
referring to land).
Here are a series of issues listed:
http://trac.osgeo.org/gdal/wiki/NetCDF
Thanks for this: I had seen some of the posts by googling around but
didn't know about this page that collects all NetCDF-related gdal issues.
Perhaps it is worthwhile to report the problem in the appropriate ticket
if reproducible.
I am not sure it can be easily reproduced, but please suggest a way if
you see one.
Ciao,
Luigi
Markus
