[GRASS-dev] v.in.lidar return filter

[Anna Petrášová]

Hi,

I want to import first return points with v.in.lidar, but I get only points
where the pulse had more then one return. So it gives me trees but not
ground or buildings. I looked in the code and there is an 'if' which skips
points with only 1 return:
http://trac.osgeo.org/grass/browser/grass/trunk/vector/v.in.lidar/main.c#L672

So the behavior looks intentional but what's the reason?

Thanks,

Anna
