clipping a raster by elevation value

Hi,

is it possible to view and export a subset of a geotiff file by specifying a particular elevation value range, eg z between 0 - 0.2 and not all z values


thanks in advance

    1. Double-click the layer containing the elevation data (or right-click > Options)
    2. Go to the Alter Elevation Values tab
    3. Enter your values in the Valid Elevation Range (i.e. 0 in Minimum and 0.2 in Maximum)
    4. OK
    5. Export the layer

    If you need to restore the elevation ranges go back to its original state, go to the same tab and hit the Restore Default Elevation Range

  • many thanks, I thought I had looked far and wide but no! Its a great inbuilt feature.

    cheers
