I recently requested DEMs for my area of interest. The data has however arrived in ORT file format - how do I create DEMs from this data in QGIS? When I open the files in Notepad there are three columns which respectively contain x and y co-ordinates in m (Hartebeeshoek Lo31) and a third column containing the height value.

Do you want to create a raster or a TIN? – underdark Dec 3 '12 at 6:56
I would like to create a raster – Bernie Dec 3 '12 at 7:34

Try the 'Add Delimited Text Layer' plugin (blue rectangle). With that plugin you can create a point-layer which you then can use directly or you can rasterize using the vector to raster option.

Thanks, tried this, but it didn't work unfortunately. – Bernie Dec 4 '12 at 12:51
