  • It depends on the format of the text file. Can you add some sample lines into your question?

In GRASS GIS, use r.in.arc for the import or simply r.in.gdal (Menu: File -> Import raster data -> Common formats import). This should read the file right away.

The format looks like AAIGrid, see How can I convert a ascii file to geotiff using Python? for an example.

You can use gdal_translate to convert it to geotiff:

gdal_translate -of "GTiff" fname.asc outname.tif

The file extension .asc is important to tell gdal which format to use.

Or use the python code from the linked question.
