for the record, the problem is that for Corine Land Cover 2012, the Coordinate Reference System embedded in the raster data is
LOCAL_CS[“Geocoding information not available Projection Name = ETRS_1989_LAEA Units = meters GeoTIFF Units = ot”,
UNIT[“unknown”,1]]
while it should be
PROJCS[“ETRS89 / LAEA Europe”,
GEOGCS[“ETRS89”,
DATUM[“European_Terrestrial_Reference_System_1989”,
SPHEROID[“GRS 1980”,6378137,298.257222101,
AUTHORITY[“EPSG”,“7019”]],
TOWGS84[0,0,0,0,0,0,0],
AUTHORITY[“EPSG”,“6258”]],
PRIMEM[“Greenwich”,0,
AUTHORITY[“EPSG”,“8901”]],
UNIT[“degree”,0.0174532925199433,
AUTHORITY[“EPSG”,“9122”]],
AUTHORITY[“EPSG”,“4258”]],
PROJECTION[“Lambert_Azimuthal_Equal_Area”],
PARAMETER[“latitude_of_center”,52],
PARAMETER[“longitude_of_center”,10],
PARAMETER[“false_easting”,4321000],
PARAMETER[“false_northing”,3210000],
UNIT[“metre”,1,
AUTHORITY[“EPSG”,“9001”]],
AUTHORITY[“EPSG”,“3035”]]
Apparently the creators of the data tried to hide the Coordinate Reference System in the GIS data available for download.

You’re right I wasn’t using the gdal commands that come with OSGeo4W (with that version of gdal it’s working well), I was working with a version of gdal that I’ve compiled from source. So probably some flags had to be set during the compilation, but I forgot to do so.

Thanks Markus for your reponse.
I tried the gdalwarp command to reproject the land cover raster to WGS84 using the following command:
gdalwarp -s_srs EPSG:3035 -t_srs EPSG:4326 C:\Data\Corine-Land-Cover\g100_clc12_V18_5a\subset.tif C:\Data\Corine-Land-Cover\g100_clc12_V18_5a\subset-wgs84.tif
But I’m not sure how to provide the csv file it’s asking for to interpret the projection:
ERROR 4: Unable to open EPSG support file gcs.csv. Try setting the GDAL_DATA environment variable to point to the directory containing EPSG csv files.
The only csv file provided with this land cover archive is inside the Legend folder (clc_legend.csv), which gives the index of each type of land cover.
Do you have any idea where to locate this gcs.csv file it’s asking for, and how to provide it on Windows (should I add an environment variable set to the path of this file)?
this gcs.csv file is part of a standard GDAL installation. GDAL uses by default its own gcs.csv file, there should be no need to specify this file or GDAL_DATA explicitely.
It seems that something is wrong with the GDAL installation. Are you using gdalwarp from OSGeo4W?
Best,
Markus

Hi Hakim,
Try r.import (https://grass.osgeo.org/grass72/manuals/r.import.html).
ETRS LAEA (EPSG:3035) is of course “supported”.
True, but a coordinate reference system not included in the input data, therefore r.import will not work and you need to define the CRS (EPSG:3035) manually.

Subject: [GRASS-user] Unable to open the Corine land cover map using GrassGIS 7
Hi,
I’m unable to open the Coring Land cover map (100m accuracy version) for Europe using GrassGIS, which can be downloaded from http://land.copernicus.eu/pan-european/corine-land-cover/clc-2012.
Apparentely the coordinate system of this land cover map isn’t supported (The projection is ETRS89 (EPSG:3035)), while the projection of the location I’m trying to import the raster to is WGS84 (EPSG:4326). Here is the error shown in GrassGIS: ERROR: Coordinate reference system not available for input <C:\Data\Corine Land Cover\g100_clc12_V18_5a\g100_clc12_V18_5.tif>
Is there a workaround in GrassGIS to open this image?
Otherwise which tool should I use to reproject it?
Thanks.
Hakim.
