Many thanks for responding. I have downloaded a GTOPO30 tile in
geotiff format but am perplexed as to how to proceed. Adding it to a
QGIS project produces a black and white image. It seems I have to
process the image somehow to make it useful visually - could anybody
point me in the direction of of to do this.<br>
<br>
With grateful thanks<br>
