#3651: Missing classification from v.lidar.edgedetection ------------------------+---------------------------------- Reporter: balagates | Owner: grass-dev@… Type: defect | Status: new Priority: normal | Milestone: Component: Vector | Version: 7.4.0 Resolution: | Keywords: lidar, edgedetection CPU: OSX/Intel | Platform: MacOSX ------------------------+----------------------------------
Comment (by mmetz): Replying to [ticket:3651 balagates]: > The man page for v.lidar.edgedetection describes > > The output will be a vector map in which points has been classified as TERRAIN, EDGE or UNKNOWN. > > On the "output" I see a database table named <name>_edge_interpolation with columns > > Column 1: ID:INTEGER:20 > Column 2: Interp:REAL:20 This table is attached to layer 3 holding interpolation results for internal use. > > I do not see a table for output=<name> nor do I see the following > > TERRAIN (cat = 1, layer = 1) > EDGE (cat = 2, layer = 1) > UNKNOWN (cat = 3, layer = 1) > This is correct, there is no table attached to layer 1. Category values are stored with the geometries. You can display points classified as terrain with `d.vect layer=1 cats=1`. > Later steps in the workflow at the bottom of the man page do not provide all the output I expect, presumable because this classification is missing. The classification is not missing, it is stored as category values without an attribute table. -- Ticket URL: <https://trac.osgeo.org/grass/ticket/3651#comment:2> GRASS GIS <https://grass.osgeo.org>
