Dear all, I imported into my postgis database my DEM thanks to raster2pgsql.
After the import, i loaded my raw dem file (.asc) and my pg dem raster file into qgis to make sure that the altimetric values were identical. Unfortunatly, i noticed a z difference between the 2 data (often 3-5 meters, sometimes more). Below, you can read my small file comparing the metadata of the 2 data (on the left, raw dem file; on the right, postgis dem raster) : Raster_compare.pdf <http://postgis.17.x6.nabble.com/file/n5006415/Raster_compare.pdf> Why this difference? How can I do so that my pg data is really identical to my raw asc file? In advance, thank you.
