[GRASS-user] GRASS and GEE integration

Hello everyone, I (finally) recently found out about some of the great capabilities of Google Earth Engine.It is great to be able to get access to so many satellite images and datasets and process them without having to download them, build databases, and process them on local computers.

[GRASS-user] rgrass7 and rmarkdown: how to avoid showing the percentage of processing

Hi, when using rgrass7 and rmarkdown, is there a way of avoiding showing the percentage of processingo of each command within execGRASS?It might get really polluted, mainly when I perform a loop or many processings.See the figure below: I tried adding "message = FALSE, warning = FALSE" to the

[GRASS-user] r.neighbors vs r.resamp.filter

Dear all, I am working with human infrastructure data (houses, trails, roads and railways, dams, etc) and I need to create maps of density (in space) of each type of infrastructure, for different spatial extents (i.e. considering different neighborhood sizes). So far I've been using r.neighbors

Re: [GRASS-user] r.neighbors vs r.resamp.filter

nal region, as GRASS internally is using nearest neighbour method for resampling – the result might not be what you expect to have. TL;DR: for same resolution output – r.neighbours for different resolution (e.g. count per km²) – r.resamp.* Māris. trešd., 2021. g. 3. nov., plkst. 15:26 — lietotājs

[GRASS-user] r.mfilter do not process map edges

Hello, I am performing neighborhood analyses with the r.mfilter module.It is very good because of its versatility - one can define the filtering matrix as one wants.However, it does not process the edges of the map, or at least it seems so.If the filter matrix size is e.g. 25x25 pixels, the

[GRASS-user] grass command to subset the columns of a vector

Dear list, Is there a GRASS GIS command (maybe a v.db.* one) to subset, in a single command, the columns of a vector? What I have: vector "vect" with 5 columns "a, b, c, d, e" in the attribute tableWhat I want: vector "vect_sub" with only, for instance, "a, c, e" I can use v.extract to subsample

Re: [GRASS-user] grass command to subset the columns of a vector

sing dplyr::select(vector1, a, e). I guess in PostGIS it is also possible to do that with "SELECT statements", even though I am less skilled there. It would be great to have a module in GRASS to do it as well... BestBernardo Em quarta-feira, 9 de fevereiro de 2022 09:28:06 GMT+1, Markus
