Re: [GRASS-user] Uniform random raster

[Thomas Adams]

Giuseppe,

Unless I have misunderstood, in GRASS use r.mapcalc...

First set you region for your area of interest, for example:

g.region -dp e=2614612.5 w=1423987.5 n=-4624387.5 s=-5862637.5

Then:
r.mapcalc expression="outputMap=25.4"

where 25.4 is your value of interest, and finally:

r.out.gdal input=outputMap output=outputFileName format=GTiff

Best,
Tom

[GRASS-user] GRASS GIS 7.03 for Mac OS X, problem with wxPython (missing)

[Michael Barton]

The packaging seems to have gone awry. I've been out of the country and then 
sick since returning. Once I get well enough to get to the office, I'll try and 
fix this.

With the 7.0.3 version of  GRASS GIS on the Mac (M.Barton)
   I can only launch GRASS-7.0.app (7.0.3) in
text mode.

When I try to launch the App or use g.gui wxpython in the Grass shell the
error is:

"Launching  GUI in the background, please wait…
ERROR: wxGUI requires wxPython. No module named wxversion

In the 7.0.2 version, wxPython is installed in
/Applications/GRASS-7.0.app/Contents/MacOS/etc/python (wx, wxpython and
pyparsing.py and wxversion.py) and it works.

But none of these files/folders exist in the same folder of the 7.0.3
version

Compilation error ?

The size of the zip files are also different (80.19 and 83.89 for GRASS 7.01
and GRASS 7.02, 35 .12 for GRASS 7.03)

Many thanks

Please see https://trac.osgeo.org/osgeo4w/ticket/413

Unfortunately I haven't found time yet to implement the simple R-winGrass
coupling into Osgeo4w which is already working in standalone winGRASS. 

As Veronica mentioned, rstudio should work in the newest Osgeo4w and
standalone winGRASS ; R and rstudio should work only in standalone winGRASS. 

I hope to find time in the next weeks.

Re: [GRASS-user] grass-user Digest, Vol 118, Issue 18

[Blumentrath, Stefan]

Hi Rengifo,

The issue is unfortunately more than just the GUI. You would be able to run the 
module on the command line if that was the case, but not even “r.terraflow 
--help” will give you any output. However, I am pretty sure r.watershed will 
provide you with what you are looking for and it is also able to handle huge 
datasets!

BTW: The paper you reference is a bit old. I recommend having a look at this:
sil.uc.edu/pdfFiles/.../JasiewiczMetz2011GRASS.pdf

As for you specific project:
The “Stream Power Index” might be of interest for you. It got implemented in 
r.watershed after we ran the module (and after the article above got 
published), so that output is missing from the data we have...

Anyway, I will see what I can do to provide you with the data (input and 
output, which includes TCI). Of course we used MFD, but we did not account / 
weight surface runoff as we had no suitable runoff data for the neighboring 
countries (and also for Norway we only had aggregated data for 1961-1990 with 
1km2 resolution)...

I will check if our FTP is able to handle the amount of data and contact you 
offline when I have a solution for that...

Hilsen,
Stefan

Subject: Re: [GRASS-user] grass-user Digest, Vol 118, Issue 18

dear grass community,
thanks a lot for the hints. Yes, indeed it was under hydrological modelling. 
But I still keep getting an error when  I try to open r.terraflow from the GUI, 
which is the reason I thought , in the first place, it was not installed.

Here is the error hope someone kan help me with it.

Traceback (most recent call last):

:
Unable to fetch interface description for command
'r.terraflow'.
Details: C:\OSGEO4~1\bin\python.exe: can't open file
'r.terraflow': [Errno 2] No such file or directory

It basically says that tha  file is not available.


As for the  question from  Blumentrath Stefan:

Yes, Stefan I am working with Norwegian data The same resolution as you. I am 
using  DTM10 from Statens Kartverk. Why  r.terraflow? Well, for this purpose it 
seems  to be the best algorithm.

Currently, I am proposing a combined approach (geomorphons+TCI (r.terraflow 
based), for  locating areas, where our  potential mass movement modelling 
(based on flow-r) fails to model the outreach of those mass movements.  
Specifically, I am looking at areas on alluvial fans located just below the 
footslopes, where phenomena like debris flows might change their rheological 
behavior, due to changes in the slope gradient of the alluvial. r.terraflow is 
use to model water accumulation and TCI in these areas. The idea is  to 
establish some sort of threshold, using the TCI, where potential flows paths 
can be delinated as an extension of the alredy existing model. e.g town of Kvam

Basically, these areas are looked upon as flood areas, and for this  purpose 
seems r.terraflow to be the best, according to some authors 
https://books.google.no/books?id=svwfypEvPwEC=PA94=PA94=terraflow+panam%C3%A1=bl=NN5mfSaXm4=UX4mZ-6fB5aYdKGKGLC0HQRfmdc=no=X=0ahUKEwi3vfOS3fTKAhWrJZoKHfY-CqoQ6AEIIzAA#v=onepage=terraflow%20panam%C3%A1=false


However, I would  appreciate  to get a copy of  the data you refered to, given 
you used MFD and not SFD to calculate it, since I am interested on diffuse 
waterflow and not chanalised one.

Thanks in advance

Re: [GRASS-user] grass-user Digest, Vol 118, Issue 18

[Rengifo Ortega]

dear grass community,thanks a lot for the hints. Yes, indeed it was under 
hydrological modelling. But I still keep getting an error when  I try to open 
r.terraflow from the GUI, which is the reason I thought , in the first place, 
it was not installed.  

Here is the error hope someone kan help me with it.

Traceback (most recent call last):
  File "C:\OSGEO4~1\apps\grass\grass-7.0.3\gui\wxpython\lmgr
\frame.py", line 776, in OnMenuCmd

GUI(parent=self, giface=self._giface).ParseCommand(cmd)
  File "C:\OSGEO4~1\apps\grass\grass-7.0.3\gui\wxpython\gui_
core\forms.py", line 2354, in ParseCommand

raise gcmd.GException(e.value)
core.gcmd
.
GException
:
Unable to fetch interface description for command
'r.terraflow'.
Details: C:\OSGEO4~1\bin\python.exe: can't open file
'r.terraflow': [Errno 2] No such file or directory
 
It basically says that tha  file is not available.

As for the  question from  Blumentrath Stefan:

Hi,

I think its comes with the standard installation of GRASS. I find it,
and most likely you too, under_

"raster --> hydrologic modeling --> Flow accumulation".

HTH,

Stefan
