I'm working on windows 7 64 bits, postgis 2.01. I have to import ECW files into my PostGIS database. Unfortunately, my PostGIS seems to has been compiled without gdal ecw support.When i do a raster2pgsql -G, ECW does not appears.
I have tried to follow instructions erected in this following post :
How to add ECW support to GDAL bundled with PostGIS Windows
So I paste the raster2pgsql.exe into my C:\Program Files\PostgreSQL\9.1\gdal-data folder. And i paste gdal19.dll from C:\Program Files (x86)\Quantum GIS Lisboa\bin toward C:\Program Files\PostgreSQL\9.1\bin. I rename the dll like libgdal-1.dll.
But it does not work and i can't import ecw with raster2pgsql.I have an error message saying : application error.For information/. Moreover, when i do a SELECT postgis_full_version();
"POSTGIS="2.0.1 r9979" GEOS="3.3.5-CAPI-1.7.5" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.9.1, released 2012/05/15"
And my qgis 's gdal has been also compiled with gdal 1.9.1.
Moreover, for information, my GDAL_DATA (environment system variable) pointed to C:\Program Files\PostgreSQL\9.1\gdal-data
How do I use ECW with PostGIS?
I have to use this ECW format. My client give to me data with this format and I did not convert raw data in ECW with a proprietary software.
