Comment (by mlennert): Replying to [ticket:3494 pitstop]: > Hi Community, > > I wanted to use r.thin on a raster map before r.to.vect on the result but r.thin crashes after 84 passes every time. Smaller number of iterations run without any problems. I was able to reproduce the error by using r.thin on the elevation.dem from the Spearfish data set. While this should probably be handled more gracefully, could you explain what you are trying to do with r.thin ? Why would you run r.thin on a DEM ? r.thin is meant to thin raster lines (represented by some form of discrete pixel values) to single pixel width so as to make their vectorisation possible. Running it on a raster map with a continuous variable doesn't make sense in my understanding. -- Ticket URL: <https://trac.osgeo.org/grass/ticket/3494#comment:1> GRASS GIS <https://grass.osgeo.org>
