13. Back to the digital elevation data. Move the downloaded file from GeoBase to your newly created DEM folder.
Next navigate to your OziExplorer directory (mine is under C:\OziExplorer\OziExplorer) and start the program called "oziUnGzip.exe".
Click on the "Select File" button and navigate to the DEM folder in OziExplorer (mine is in path C:\OziExplorer\OziExplorer\Elevation Data\dem) and select the Zipped file (021G02.zip in our example). Then press the "Open" button.
The program will run and create the necessary files. A "Done" button will pop up when finished. Close the program.
If we check our dem folder now, we can see the files.
