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 2: Interp:REAL:20

 This table is attached to layer 3 holding interpolation results for
 internal use.

 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.
