[GRASS-user] v.lidar.edgedetection -e option

The online documentation for v.lidar.edgedetection show’s an -e option to get an estimate of point density (http://grass.itc.it/grass65/manuals/html65_user/v.lidar.edgedetection.html). In the GUI I don’t see the -e option, and when entered at command line it is not recognized.

If this option was removed, is there another way to estimate the spacing of a lidar point cloud?

GRASS 6.5 & Kubuntu 9.10

Thanks,
Mark

Hi,

2010/4/6 M S <mseibel@gmail.com>:

The online documentation for v.lidar.edgedetection show's an -e option to
get an estimate of point density
(http://grass.itc.it/grass65/manuals/html65_user/v.lidar.edgedetection.html).
In the GUI I don't see the -e option, and when entered at command line it is
not recognized.

hm, on my machine

v.lidar.edgedetection --help
...
  -e Estimate point density and distance
        Estimate point density and distance for the input vector
points within the current region extends and quit
...

Seems to be OK. Martin

Mark,

how old is your installation? There was a major important overhaul a few months
ago in v.lidar.*. Perhaps you need to update?

Markus

I’ll try updating. It looks like it was installed around February 11.

Much thanks,
Mark

Just installed updated 6.5svn, and the -e option is indeed present.

Thanks for the help.
