[GRASS-user] finding distance to raster features in a given direction

2015-03-03 Thread Nick Gauthier
Hi, Given a binary land/sea raster, I’m trying to calculate the shortest distance from each land cell to the sea within a range of wind directions (e.g. 85-95 degrees from north). The calculation is basically r.grow.distance with an extra parameter for the range of directions (or a raster of the i
