[Solved] Problems with DTM to Tiff

Hi, I've been trying to get some kind of image Tiff for two days by taking it out of the QGis. I've been testing for two days and all I get are bugs or poorly detailed terrain. I do not know how to handle Qgis and it is very difficult to obtain any kind of result.

I also don't know where to get this DTM information for Spain. This tool seems good but there are many impossible steps to follow, I am an experienced person in Unreal, but this is beyond my knowledge.

If I do not obtain a solution, I will decline the annual contract, since it is not a useful tool for my work.

Attached the error that I get from the output log.

I would appreciate a solution.

It appears from the log that TerraForm is finding 3 bands (RGB?) and no height data.

Where did you get the data from? Is it from a WMS service by any chance? (WMS doesn't provide height/vector data, just an RGB image of the data, like a screenshot of a Microsoft Word document..)

You can get loads of really good GIS data for Spain here:

https://centrodedescargas.cnig.es/CentroDescargas/locale?request_locale=en

Completely FREE, high resolution, and easy to download instantly.

Once you've downloaded the correct files, following the steps here should be easy:
