[GRASS-user] Invitation: Virtual toast for GRASS GIS 40th birthday
Dear all, Our beloved GRASS GIS becomes 40 years old! Let's meet this *Saturday July 29th at 17:00 UTC* for a virtual toast and celebration 🎂🍻🎉 Some local times here: https://www.timeanddate.com/worldclock/meetingdetails.html?year=2023&month=7&day=29&hour=17&min=0&sec=0&p1=485&p2=207&p3=37&p4=25&p5=204&p6=197 . I'll share a link here shortly before the meeting. See you soon! Vero -- Dra.

Re: [GRASS-user] v.to.rast -d segmentation fault Re: Surfaces with faults
And at the end I found the solutions: after a v.to.rast at the desired resolution I can choose the line width with r.buffer and at the end I can use v.surf.rst, with raster line mask > v.surf.rst --overwrite input=fosso_punti zcolumn=z elevation=fosso_dem_rst mask=line3d_rast smooth_column=vdop segmax=60 dmin=0.2 dmax=5 !!!

Re: [GRASS-user] v.to.rast -d segmentation fault Re: Surfaces with faults
Almost eureka spline with tension only for point of the ditch is possible with r.resample.rst > r.resamp.rst --overwrite input=fosso_punti_rast@granello ew_res=0.1 ns_res=0.1 elevation=fosso_dem_rst@granello overlap=2 tension=40. but the result in width of the line is too big and also the profile is with "terraces" Il giorno mar, 25/07/2023 alle 08.33 +0300, Maris Nartiss ha scritto: > Please provide your input data and computational region settings.
