[GRASS-user] r.landscape.evol- reverse erosion modelling

[Maria Cecilia Zalazar]

Dear community. I wonder if it is possible to use r.landscape.evol to
reverse modelling. I mean, starting from the present topography, erosion
and deposition is calculated backwards in time by adding erosion values and
subtracting deposition values.
Some time ago, Peeters et al (1) used this strategy in WaTEM LT. I think it
would be a few changes to the r.landscape.evol script.

Thanks very much in advance

[Maria Cecilia Zalazar]

Thanks for your answer Vaclav!
Some time ago I was in contact with the code-author. She made some changes
but now unfortunately doesn't have the capacity to update the tool. Anyway,
I'll mention this to her and try to submit the addon in the grass
repository. I'll be in touch!

Best,

María Cecilia

[GRASS-user] r.terrain.geom

[Maria Cecilia Zalazar]

 data.zip

Dear Grass community, there is a very interesting grass add-on
(r.terrain.geom) that extracts fluvial terrace-like surfaces from digital
elevation models and also creates a pdf plot with graphs showing the
terrain characteristics and logic of process (R interface).
https://github.com/edinaj0zs4/terrace_extraction_grassgis
(Józsa, E., 2019. Geomorphometric application of quasi-global DEMs for
semi-automated geomorphological mapping. University of Pécs)

My winGrass version is 8.2 and I had to modify the TERRACE_jozsa (R-script)
in order to update the interface required package (rgrass instead
of spgrass6). Also the ggplot2 version was necessary to update. I'm sending
the new R script.
Actually, this is not an available add-on script via g.extension in oficial
repositories. I'm not sure which are the requirements to do this (some
improvements or check?), or if it is possible to make it accessible via a
public repository.
I´m sending data for easy checking.

Thanks very much in advance!

Regards!
Title: GRASS GIS manual: r.terrace.geom









NAME
r.terrace.geom  - Extract terraces from DEM
KEYWORDS
raster, terrain, geomorphology, terraces, landform
SYNOPSIS
r.terrace.geom
r.terrace.geom --help
r.terrace.geom [-tfrl] elevation=name  [slope_percent=name]   [limit=integer]  raster_water=name flowdir=string  [azimuth=integer]  report=name terrace_map=name  [terrlevel=string[,string,...]]   [--overwrite]  [--help]  [--verbose]  [--quiet]  [--ui] 



Flags:

-t
Remove valleys of tributaries based on geomorphons map

-f
Filter slope map

Analyse right bank area (set only if elevation is total watershed)

-l
Analyse left bank area (set only if elevation is total watershed)

--overwrite
Allow output files to overwrite existing files
--help
Print usage summary

DESCRIPTION

r.terrace.geom flexible terrain analysing tool is developed for the delineation and quantifiable analysis of terrace remnants. 
The algorithm determines cells potentially belonging to terrace surfaces based on local slope characteristics and a minimum area size threshold.

NOTES

The algorithm cuts up the area into parallel sections in flow direction and determines cells belonging to terrace-like surfaces. 
As a result an output report is created that contains a histogram of altitudes, a swath profile of the landscape, scatter plots 
to represent the relation of the relative elevations and slope values in the analysed sections and two final plots showing the 
longitudinal profile of the river with the determined height ranges of terrace levels and a histogram of the values.

Dependencies:

R 3.x (packages: spgrass6/rgrass7, ggplot2, data.table) & r.geomorphon add-on

Hello, try doing double click on the legend (in pointer mode) to set object

[GRASS-user] Geo-Vox modeling

[Maria Cecilia Zalazar]

Hello everybody, I´m interested in a new web-GIS platform for Geologic
Voxel modeling and visualization recently published (Nemoto, T., Masumoto,
S., Raghavan, V., Nonogaki, S., & Nakada, F. 2020. Development of open
source Web-GIS platform for three-dimensional geologic modeling and
visualization).

It comprises GRASS and others FOSS4G and I wonder if anybody knows if I
could get access to Geo-Vox in any way (OSGeoLive virtual machine or
desktop application).

Any free alternative geologic voxel model will be welcome.

Thanks in advance!

Cecilia.

[GRASS-user] python 'NamError' r.landscape.evol

[Maria Cecilia Zalazar]

Hello. In previous (win)grass versions I was able to work with
r.landscape.evol addon. Now with 7.8.2 wingrass version appears a python
NameError:



*r.landscape.evol elev=DEM_21x21@PERMANENT initbdrk=0 smoothing=no
prefx=levol_test outdem=elevation_test outsoil=soildepth_test number=1*

*Traceback (most recent call last):*

*  File "C:\Users\USUARIO\AppData\Roaming\GRASS7\addons/scrip*

*ts/r.landscape.evol.py ", line 665, in
*

*f = file(statsout, 'wt')*

*NameError: name 'file' is not defined*



It seems that the script was written in Python < 3 and ‘file()’ is not
supported in Python 3. Is possible that the addon needs to transform into
valid Python 3.x code?

Thanks for your help!

Re: [GRASS-user] TR : Extensions

Hello. I've been suggested this workaround and now Its works fine:

Locate the g.extension.py script, copy and rename it and modify one line
(search for cz). (You'll need an editor like Notepad++ to avoid issues with
carriage returns). Then run using File > Launch Script.

base_url = "http://wingrass.fsv.cvut.cz/"; \
   "grass%(major)s%(minor)s/%(platform)s/addons/" \

Re: [GRASS-user] WINGrass: g.extension – Not found

[Maria Cecilia Zalazar]

Hello again, when I run r.landscape.evol, now I get this error:

Traceback (most recent call last):
  File "C:\Users\USUARIO\AppData\Roaming\GRASS7\addons/scrip
ts/r.landscape.evol.py", line 665, in 
f = file(statsout, 'wt')
IOError: [Errno 13] Permission denied:
u'PERMANENT_levol_lsevol_stats.csv'

it´s appears as if the path to the rules file must be error or missing?
My user is administrator.

Thanks for your help!

[GRASS-user] WINGrass: g.extension – Not found

[Maria Cecilia Zalazar]

I would like to know if there are news about installing extensions from the
repository. I´m ussing Grass 7.6.1 in Windows.

However, I´ve download zip file (r.landscape.evol) and I tried to install
it manually:

g.extension extension=r.landscape.evol
url=C:\OSGeo4W64\apps\grass\r.landscape.evol.zip
Downloading precompiled GRASS Addons ...
ERROR: Extension  not found

I tried different paths, / instead \, but i can´t get it...

Thank you!

[GRASS-user] Grass GIS: g.extension – Not found

[Maria Cecilia Zalazar]

Hello. I'm having problems trying to compile r.landscape.evol and another
extensions, on the 7.6.1 version of GRASS from the g.extension command. It
does not found the file in the default repository. I am running Windows 10.
It´s seems the repository does not work.  Thanks for your help
