I am trying to convert a digital elevation model in txt file format to a raster file (tiff) with qgis.
The file format is *.dat. The coordinate system is Gauss Krüger, Bessel, 5. meridian.
First I imported the txt file with the appropriate coordinate system. Now I want to convert it to a raster file. However the viewed data are black and I dont see any heights. What did I do wrong? Follow the link to view the screenshot of the imported dem in qgis: Screenshot qgis
When zooming in it looks like this: Screenshot zoomed in
This is an example of the data:
LATITUDE LONGITUDE HEIGHT 5390.0125 5659.9875 258.6 5390.0125 5659.9625 252.6 5390.0125 5659.9375 243.9 5390.0125 5659.9125 237.1 5390.0125 5659.8875 234.5 5390.0125 5659.8625 231.2 5390.0125 5659.8375 233.7
