#3651: Missing classification from v.lidar.edgedetection
----------------------------------+-------------------------
Reporter: balagates | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone:
Component: Default | Version: 7.4.0
Keywords: lidar, edgedetection | CPU: OSX/Intel
Platform: MacOSX |
----------------------------------+-------------------------
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
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)
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 database for my project is SQLITE. The import of the Lidar data
appears to have a complete list of columns including x, y, z, intensity,
return, n_returns, scan, edge, etc.
This is the first time I have run through this workflow so I could have
messed something up. It would be nice if someone could verify they get
similar results.
