[Portugal] Re: Problemas na definição do sistema de coordenadas de geotiff

[cremat0rio]

Muito obrigado pelas vossas dicas.

Fazendo:
# gdal_merge.py -o ficheiro.tif -co tiled=yes -co tfw=yes -co bigtiff=yes -v
*.tif
e depois:
# gdal_translate -of GTiff -co "PROFILE=GeoTIFF" -co "INTERLEAVE=PIXEL" -co
"TILED=YES" -a_srs EPSG:27492 ficheiro.tif ficheiro-georeferenciado.tif
fica tudo a funcionar bem, mas... o geoserver não aceita o ficheiro,
continua a dizer:
Could not list layers for this store, an error occurred retrieving them:
Unable to acquire a reader for this coverage with format: GeoTIFF

O gdalinfo diz:
gdalinfo ficheiro-georeferenciado.tif
