If you compare the path to the images shown in the properties and in the error reports from GDAL, you can see that the accented letter á in the folder name is missing from the latter - this suggests to me that GDAL is having a problem accessing folders with that character - try renaming the folder and running the command again.

Hi

I am trying to merge two raster dems. The project, the layers are all on the same crs (EPSG 4326) This is what I have:

ERROR 4: `C:/Anita_Tepoztln/Rasters/e142.tif' does not exist in the file system,

and is not recognised as a supported dataset name.

ERROR 4: `C:/Anita_Tepoztln/Rasters/e145.tif' does not exist in the file system,

and is not recognised as a supported dataset name.

Traceback (most recent call last):

File "C:\PROGRA~2\Quantum GIS Lisboa\bin\gdal_merge.py", line 509, in

sys.exit(main())

File "C:\PROGRA~2\Quantum GIS Lisboa\bin\gdal_merge.py", line 392, in main

ulx = file_infos[0].ulx

IndexError: list index out of range

I am able to load both raster and check their propertieies, for instance

Driver: GTiff/GeoTIFF Files: C:\Anita_Tepoztlán\Rasters\e145.tif C:\Anita_Tepoztlán\Rasters\e145.tif.aux.xml Size is 7200, 3600 Coordinate System is: GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433], AUTHORITY["EPSG","4326"]]

I do not know waht is wrong, any ideas are welcome....

I am using Lisboa standallone installer in win 7 64 16gb of RAM
