[Qgis-user] Background raster image at circa 1:10 million?

[Martin Pescador]

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.

With grateful thanks
