Excellent, that is the way to do it! Thanks On Wed, Dec 27, 2017 at 11:14 PM, Vaclav Petras wrote: > [cc'ing the list] > > One way to do the spatially variable shift is to do what I suggested > earlier, but instead of the last step (computing average), interpolate a >

Re: [GRASS-user] Level LiDAR data to gps points

[cc'ing the list] One way to do the spatially variable shift is to do what I suggested earlier, but instead of the last step (computing average), interpolate a surface from the differences at each point using, e.g., v.surf.rst with zcolumn option set to the difference column computed earlier. For

Hi, I have some LiDAR data that was not levelled properly and I was wondering does anybody know of a way of levelling the las files to gps points? Thanks in advance -- Le gach dea ghui, *Shane Carey* *GIS and Data Solutions Consultant* ___ grass-user
