I know I've done this before, but I can't for the life of me find the functionality again.
I am trying to manage some contours generated from LIDAR. Even with using just last returns I have lots of spurious contours. Before, I was able to delete segments shorter than a given length threshold. But I can't remember how. v.edit allows removal *areas* smaller than certain sizes, and it also removes "dangles" but not just regular line segments? Any help? Semi-related: LIDAR data from Erie County, NY used to be available for download as bare earth, and even you could specify a contour interval and download that as a shapefile. Can't for the life of me find that either! I think the bare-earth are now in the 1/3 arcsecond NED DEM, downloading that now over my slow DSL; will take a look. Maybe not so many spurious contours if I generate them from 1/3 arcsecond sized data, but we will see. Thanks.
