Hi, I'm (slowly ;) getting to grips with GRASS, with the aim of turning the arctic ice maps fromĀ http://ice-glaces.ec.gc.ca/ (.e00) into KML.
The maps contain vectors for the entire Canadian arctic coastline. Slarty Bartfast would've loved the fiddly bits, but I'd like to smooth out some of this detail to reduce the size of the maps. I can do this (radically!) with v.generalize if I first extract just the land areas. v.generalize -c --overwrite input=land@arctic output=land_smoothed type=boundary method=hermite threshold=100000 angle_thresh=20 But if I try and use v.generalize with the same parameters on a map with ice, sea and land areas, selecting the land areas with a where clause, no smoothing takes place. v.generalize -c --overwrite input=a11_centroids@arctic output=a11_smoothed method=hermite threshold=100000 angle_thresh=20 where=a_legend='Land' I only want to smooth boundaries with land - I don't want to touch the ice-ice or ice-water boundaries. Any idea how I can achieve this? Also I came across the following "[GRASS-dev] v.generalize no longer corrupts areas and area attributes": http://lists.osgeo.org/pipermail/grass-dev/2011-January/053101.html Is GRASS 7 stable enough for day-to-day use?
