[Therion] NODATA value in loch surface

2013-07-05 Thread Wolfgang Zillig
Hello Jonny, I assume that this is not possible. Are the holes in your elevation data big? I would suggest that you interpolate the missing data. This can be done tools from gdal-library: http://www.gdal.org/ Ready compiled packages are available for Windows from OSGeo4W http://trac.osgeo.org/o

[Therion] NODATA value in loch surface

2013-07-03 Thread Jonny Prouty
Hello all, My apologies in advance if I've overlooked something, but is there a way to instruct Loch to NOT draw elevation data equal to a certain value? For instance, in my current model, I do not want Loch to draw any elevations that are equal to 0. Is this possible? Thanks very much in advance!
