[OSGeo-Discuss] What GeoSpatial Open Source Software do Surveyors use?

[maria.brovelli at diiar-topo.polimi.it]

Dear Cameron
if you are interested also in LiDAR data filtering (to obtain from the  
LiDAR point cloud the digital terrain model), we developed  commands  
into GRASS. They have to be used in sequence.

http://grass.osgeo.org/gdp/html_grass64/v.lidar.growing.html
http://grass.osgeo.org/gdp/html_grass64/v.lidar.correction.html
http://grass.osgeo.org/gdp/html_grass64/v.surf.bspline.html

A detailed description is available here:

a more recent and summarised version can be found here:

http://geomatica.como.polimi.it/corsi/remote_sensing/LiDAR_filtering_with_GRASS-lab4.pdf

We worked also on calibration of  the filtering parameters (around 20  
parameters) by integrating the USGS UCODE and GRASS. Details are  
available here:

I hope it helps.

Cheers.
Maria
