[Qgis-user] error loading tiff layer

[Richard McDonnell]

Hi,
You can gave a raster using the correct coordinates (extents) but not with the CRS assigned.
Could I suggest you utilise gdal_edit ( https://gdal.org/programs/gdal_edit.html ) and assign the CRS EPSG:3116 to the raster and try again?
You can perform this within QGIS using the Processing tools just search for “edit” and select Assign Projection just select the valid CRS from the list and run it.
Hope this helps,

Regards,

Richard.

Thanks for the reply, but the file has all the information necessary to be loaded correctly.
The file comes from arcgis, I have tried to load it with gvsig 2.5, SNAP desktop 6.0 and everything seems to indicate that they are not able to read the projection information correctly.
i keep trying

The file may not be a geotiff and therefore require a seco d file in the directory in which it resides. A .twf or .aux file with the same name as your tiff file.

regards.
I could not load a layer in tiff format. The error that qgis shows is:

"No transform is available between Unknown CRS: ENGCRS [" PCS Name = unnamed ", EDATUM [" "], CS [Cartesia ... and Unknown CRS: GEOGCRS [" unknown ", DATUM [" unknown ", ELLIPSOID [" WGS 8 ... .
No coordinate operations are available between these two reference systems ".

The file has a reference system, which is magna-sirgas from Bogota (3116), I have tried the magna-sirgas (3116) project, and wgs84 (4326) showing the same error.
The version of qgis is 3.10.2-A Coruña.
thank you very much for the help and I remain attentive
