gdal - QGIS polygonize error 4 "file does not exist in the file system"?

Monday 17 April 2017

When I try to convert a raster DEM (in .asc or geotiff format) to polygons I get the error below:

ERROR 4: `Y:/GIS/oversvmmelser/tmp/out.tif' does not exist in the file system, and is not recognised as a supported dataset name.

Any idea what the problem is?

Answer

@user30184 came with the solution.

the (quite common GIS) problem was that non-ASCII characters (like æ ø å) in the path name gets deleted.

only use ASCII characters in file paths.
