[Qgis-user] 16 bit greyscale heightmaps

[Nigel Berjak - General]

Hi Jason

What elevation data are you using to the extract heights from? Once this 
information is provided, hopefully an approach can be offered. Also, 
where in the world is your wetlands app and therefore someone may also 
be able to assist, if you don't have data already, with the best 
available elevation data?
