Re: [GRASS-user] 3D raster color coding

Try removing -r from your command (unchecking the box in the GUI). That flag is used to remove a color palette. Best, Vero El sáb., 2 jun. 2018 3:48, Francois Chartier escribió: > > Hi Veronica, > > something is odd. here are the steps - Display window is still blank and > the 3D raster has d

Hi Moritz and Helmut, Great proactive energy. Highly appreciated! For clarity, tomorrow I should install the v.class.mlR again and test it? Should I also install the needed packages first in R as stated in one of the messages? I will not have access to the same computer this weekend, but I can tr

[GRASS-user] i.maxlik yellow map

Hi Users, I have created a signature file in the g.gui.iclass (supervised classification module) and it looks correct in 'preview' and when i inspected the 'sig' file. When the signature is applied using 'i.maxlik' the result is a solid yellow colour as a layer. What could have gone wrong? Thanks

[GRASS-user] Spyder IDE with GRASS

I occasionally try to use GRASS via the Spyder IDE but have not found a solution that works so far. I am working in Windows 7 with various versions of GRASS (72, 74, 75) through the OSGEO install. My attempts include 1. Manually installing Spyder into the OSGEO python site-packages direc

[GRASS-user] Supervised Classification Tool - g.gui.iclass

Hi Users, I want to know if there is any good sources of information on the above wxlClass. I want to know roughly how large the training areas should be to prevent the module from taking several hours to process a signature. Also in the Training Area Display must i use a composite RGB image to di

Essentially, I have "exactly", I think, the same workflow in mind. So, I am in a path where you have been already. Thank you for sharing this Stefan. - Computing LST images from Landsat 8. - Instead of writing GRASS GIS native raster maps, I will switch to GeoTIFFs via r.external.out - After h

Re: [GRASS-user] GRASS GIS virtual raster data sets

Hi, Some experience with GDAL VRT and GRASS: Be aware of: https://trac.osgeo.org/grass/ticket/2837 Also note also that esp. for integer rasters, compression of one big raster map can be much better than with lots of smaller tiles [1]. So I guess cases where patching by means of a virtual raste

Hello, That's probably because that palette is for integer values ranging from 0 to 360 [0]. Try with a relative one such as viridis or bcyr. HTH, Vero [0] https://grass.osgeo.org/grass74/manuals/r.colors.html El jue., 31 may. 2018 a las 3:18, Francois Chartier () escribió: > Hi, > > I have cr
