Re: [GRASS-user] importing and cleaning overlapping polygons that are supposed to overlap

Hi Moritz Thanks for the heads-up! Yes, for overlapping buffers v.rast.bufferstats seems just perfect! IIUC, it does exactly what MM was explaining. Great! Thanks again! And thanks Stefan for the add-on! Vero El mié., 22 may. 2019 19:30, Moritz Lennert escribió: > Le Wed, 22 May 2019 19:25:1

[GRASS-user] Average height over catchment in grass gis

Dear users  I am writting you here with the hope of getting some ideas about how to caculate what Kirsten Hennrich et al., refers to as average catchment height (Ha) I found this infomation in the proceedings of an international conference called regionalisation of hydrology.  In page 184, he sa

Re: [GRASS-user] v.what.vect never ends, SQLite warning

Hi Everyone, When I try v.what.vect on a point layer and the output of a v.voronoi, after around an hour I begin getting the warnings that apparently are because of an SQLite database lock. This is not what happens with v.what.vect only. When exporting the layer to shapefile or any other format it

Re: [GRASS-user] importing and cleaning overlapping polygons that are supposed to overlap

Hi Markus, Thanks for the explanation. It is possible to import topologically incorrect vectors, but not create them within GRASS. So, as a solution to my problem, I rather create (potentially overlapping) buffers outside GRASS and import them with -c in v.in.ogr to use v.rast.stats with no loss o

Re: [GRASS-user] r.contour contour wrap

just FYI. I am (was?) using 7.6 and had errors with r.contour outputs (linux mint). Output lines would be broken in areas there was good DEM data. The lines had large gaps between some isolines where other software could make clean contour from the DEM. I downloaded and compiled 7.7 and works gre

Thanks for that info. So would a suitable strategy be to try re-synching Grass from git, then compiling and building with proj 6.1, and if that fails, try the proj 5.9.3 release? ~ Eric. From: Markus Metz Sent: May 22, 2019 12:57 To: Patton, Eric (NRCan/RNCan) Cc: grass-user@lists.osgeo.org

Markus - Yes, I am using proj 6.0.0 – built with no errors. I believe I checked out master with ‘git clone https://github.com/OSGeo/grass.git’ – so shouldn’t that fix already be present in my source tree? ~ Eric. From: Markus Metz Sent: May 22, 2019 12:25 To: Markus Neteler Cc: Patton, Eric

Re: [GRASS-user] Multiple errors building Grass 7.7svn

Hi Markus, I noted your new installation instructions for the git repo and have used those. The first error in error.log occurs in /usr/local/grass/lib/proj: test -d OBJ.x86_64-pc-linux-gnu || mkdir -p OBJ.x86_64-pc-linux-gnu gcc -g -O2 -fPIC -I/usr/local/grass/dist.x86_64-pc-linux-gnu/inc

Re: [GRASS-user] importing and cleaning overlapping polygons that are supposed to overlap

Dear all, thanks again for your answers. I found an easier way, use -c flag in v.in.ogr seems to not build topology of overlapping areas and then v.rast.stats does not complain. However, if one builds buffer areas for points within GRASS, i.e., using v.buffer, the problem appears again when buffe
