[GIS] What DEMs does QGIS support

demqgis

I am working on QGIS rasters.

What DEM file formats are supported by QGIS?

I know that QGIS can read the GDAL supported formats but not what the GDAL supported formats are.

I do not know whether QGIS supports all the DEMs supported by ArcGIS Desktop.

Settings -> Options ->GDAL gives you a reliable list what is possible with your installed QGIS version.

It might well be that some QGIS versions on some platforms do not support everything that is available in GDAL sources.

Turns out you use the CreateCopy method instead, since the Create method is indeed not implemented for the USGSDEM format:

OSGeo.GDAL.Dataset dsDem = demDriver.CreateCopy(c.outputFile, originalImage, 0, null, new Gdal.GDALProgressFuncDelegate(ProgressFunc), "Sample Data");

I must admit that after not getting many responses here, I asked this question on the gdal-dev osgeo mailing list, which is where this answer came from.

[GIS] Merging USGS DEMs in ArcMap

The conversion toolbox has a tool to convert your DEM file to a raster format. Do that first, for each DEM. Then use the "Mosaic to new Raster" tool to combine them into a single file.

You'll want to be double sure each file you want to combine is in the same coordinate system/projection and the same units. I once had a particularly odd looking hillshade from a couple DEMs I merged where adjacent tiles were in feet and meters...
