[GRASS-user] about r.threhold

[Rengifo Ortega]

Dear Grass community
First of all thanks for this great piece of  software such  as GRASS 
GIS!Recently I have been using  the  r.threshold module to extract a  river 
networks at different  DTM resolutions and different areal extent. I noticed 
that   r.threshold values varies widely as a function DEM  resolution and 
extent of watershed (areal extent). So , I have some questions, and hope 
someone in the community can shed some light on them.
Looking at the description of the module  it says : "This approach provides a 
best guess about what makes sense when looking only at the DEM"
 Question 1: means   that the results of the r.threshold module will depend on 
the resolution and  the extent of the watershed?
Looking  at the source code, I  realised that r.threshold used r.stats to 
generate a flowacc  text.file ordered in ascendent order and put into a matrix 
called  mappatella, with 3 columns defined as:
mappatella is a matrix, in the first column the value of upslope area is 
stored, 
in the second the number of cells, in the third the distance from origin is 
calculated

further in the script the distance is defined as :
calculating distance from origin of each point; origin of the plot is in low 
left point 


Question 2 : which is the origin?  is the center  of  a cell  of the corner of 
a cell?Question 3: which plot? and why  the low left point of the plot? 
 Although I understand the general aspect  of the module I still struggle to 
understand its details. I would appreciate some explanation to crarify  it 
further, since I  am using it as part of workflow within  GRASS GIS to produce 
inputs to a Distance Distribution Dynamics( DDD) model for urban enviroments.

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

[Rengifo Ortega]

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 says that it is possible to calculate  Ha  using r.statistics 
in GRASS GIS (IAHS publication no. 254). 
I have been using sofar SAGA GIS to do the job.   But recently  I am  
experiencing some memory issues with SAGA GIS. In the old versions of  SAGA GIS 
 this calculation was named catchment height.  The new versions of SAGA GIS 
require that the user calculate  the mean over catchment  (MoC) first. 
Thereafter is MoC substrated from the original DTM. The product of this is the 
average catchment height or simply catchment height. 
Have someone in this group used GRASS GIS to calculate Catchment height in 
GRASS GIS. Any  hint will be appreciated.

[GRASS-user] r.sim.water error map-- how to interpret it.

[Rengifo Ortega]

Dear Grass community,I amusing r.sim.water (SIMWE) to model depth and discharge 
of an specific rain event in a small urban watershed in the city of Oslo, 
Norway. So fareverything went ok. But, I am wondering about the output called 
Err. Inthe grass gis manuals 
https://grass.osgeo.org/grass64/manuals/r.sim.water.html describe […]the err 
raster map (the resulting water depth is anaverage, and err is its RMSE) […]. 
Q1: areerror map and depth map supposed to have the same  scale?  in this 
casefrom 0.0 – 1.87 meters Q2: Ifyes, how I am supposed to interpret RMSE . If 
I  query thecell I obtain the same value in both datasets.?  So far I 
understand RSME  (root-mean-square error (RMSE)) is a frequentlyused measure of 
the differences between values (sample and population values)predicted by a 
model or an estimator and the values actually observed. I wouldappreciate any 
help.

[GRASS-user] r.hazard.flood erroneous results.

[Rengifo Ortega]

Dear community,I gave a try to r.hazard.flood and  got  som  erroneous results, 
that indicate flood hazard (value 1) on  the hillsides. Is that possible?

I am running  r.flood.hazard in GRASS GIS 7.2.0 on a windows 10 machine. The 
DTM used has 1m resolution.
Not error messages are produced-- (below  the command output), but the  results 
do not represent the reality. The MTI map on the other hand, looks correct to 
me. Negative values on the hillside and positive values in the floodplain (see 
attachments).

Re: [GRASS-user] opening .gri anf .bin files in grass gis.

[Rengifo Ortega]

Dear community,i moved the .bin and .gri file to our ftp

ftp://ftp01.nve.no/gis/NN2000/
user: gispassord:mErcat0r ( 0 is a zero not a capital O)

There I have the two files and some png files, that shows the .gri file that I 
was able to open in Global Mapper a while ago. About the question from Markus 
Metz. Sofar, I know I know both files content the same information but in 2 
different formats. Here some explanations about the  internal structure of the 
file--- free translation from norwegian to english--:

Liten forklaring av formatet:Første linje inneholder følgendeinformasjon:First 
line contents the following  information
   57.00   72.00    1.00  33.00    0.025000    0.05 
57.00  Minste bredde (min latitude)
72.00  Største bredde(max latitude)
1.00 Minste lengde(min longitude)
33.00  Største lengde(max longitude)
0.025000 Bredde inkrement(latitude increment)
0.05 Lengde inkrement(longitude increment)
 Alle andre linjer inneholderdifferanser mellom NN2000 og NN1954.Other lines 
content difference beween old (NN54) and new model (NN2000)
Første verdi, -3.048, harposisjon lengde 1 og bredde 72, neste verdi lengde 
1+0.05 og bredde 72, så1+0.05+0.05 og 72 osv.First values -3.048 has position 1 
longitude, 72 latitude. next values  has 1+0.05 longitude and latitude 72 and 
so on ... 1+0.05+0.05 og 72

Når lengda har nådd 33, begynnerneste bredde som er 72-0.025. Første verdi  ved 
denne bredda fårposisjonen lengde 1 og bredde 72-0.025, så lengde 1+0.05  og 
bredde72-0.025, deretter  lengde 1+0.05+0.05  og bredde 72-0.025 osv.
So, when the longitude has reached 33, then it starts with the next latitude 
which is 
72-0.025. First values heres is then longitude 1 and latitude 72-0.025, so 
  longitude 1+0.05  and latitude72-0.025, then longitude 1+0.05+0.05  and 
latide 72-0.025 and so on.
 Sagt på en annen måte: etter32/0.05=640 verdier begynner en ny bredde som er 
0.025 mindre enn den forrige.
In short: after 32/0.05=640 values, a new latitude is started,which 0.025 less 
than the one before.
 End of translation-
As you see I was able to open the .gri file in a test version of global mapper, 
but I woudl rather do it in my software combination  of preference 
(grass+qgis+gdal).
 I hope the infomation above is more useful to you Markus Metz , than it was to 
me .

As for the question from Markus Neteler, the values used where standard values 
already present in in the example comman line,since I do not know how many 
columns and rows they are in the .bin file. 


Thanks for the helpbest regards.Rengifo Ortega

Is it possible that these files are not raster maps but reference

proj4?

Just a guess,

[GRASS-user] opening .gri anf .bin files in grass gis.

[Rengifo Ortega]

Dear Grass  Community.,first of all a greeting to the community. I have a 
question and hope some of you can help me with it.
I have got a .gri and a .bin file that represent  a geodetic height modell in 
Norway,which can be downloaded for free from here.  
ftp://ftp.geodesi.no/NNTrans%20-%20Transformasjon%20mellom%20NN2000%20og%20NN1954/
So, I have tried unsucessfull to import  the .bin file into GRASS GIS and the 
.gri file is not even read into GRASS GIS. Have any of you tried to open a .gri 
file in GRASS GIS.
i tried the r.in.bin with the following parameters with not success:try 1:
r.in.bin NNTrans2016A.bin out=nntranstest r=5400 c=10800 n=72 s=57 w=
1 e=33 bytes=2
try 2:r.in.bin NNTrans2016A.bin out=nntranstest r=5400 c=10800 n=72 s=57 w=
1 e=33 bytes=4try 3:r.in.bin NNTrans2016A.bin out=nntranstest r=5400 c=10800 
n=72 s=57 w=
1 e=33 bytes=8

In all three cases I got the  following error;WARNING: File Size 1577088 ... 
Total Bytes 11664
ERROR: Bytes do not match file size


Sofar I know .gri seems to be a petrosys file. Does any of you tried to do this 
before.
Best regards and thanks for any help.

Hi fellow GRASS users,

I have outputs of i.segment (object segmentation) for 30m Landsat imagery
from 4 dates. The segments are around 1 each for each imagery. How can
I use these outputs for land cover change analysis? Do I have to vectorize
these and recode the classes, or is there a more efficient way?

Thanks!

Hi all,
today, I have a problem with my release  "grass 6.4.4 with my sis "  in
windows vista.
When I open my mapset, appears this error:
"g.proj.exe ha smesso di funzionare".
Someone has an idea for a solution.
thanks in advance.

Following Anna's suggestion I had to find out that r.mode has to option 
to handle NULL values, i.e. exclude it from calculation? I need to 
aggregate rasters to polygons, with rasters covering only a small part 
of the polygon. As I realized now r.mode returns NULL in such case. 
Setting NULL with r.null null= it will return  for all of these.

Is there a solution to that problem?

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)

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

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".

[GRASS-user] r.terraflow

[Rengifo Ortega]

Dear communityrecently I update grass gis from 7.0.0 to New stable long term 
support (LTS) release 7.0.3  a on windows 7 enterprise machine. In the former 
version I had installed r.terraflow. searching for it in the 
http://svn.osgeo.org/grass/grass-addons/grass7   I did not find it. Can  
someone tell me if I am missing something here? I thought it was included in 
this release out of the box, if I understand prof.mitasova in this site 
TerraFlow.  I would like to get some  ideas how to install it in the version 
7.0.3.

Re: [GRASS-user] r.out.gdal in GRASS 7.0 beta (windows OS) fails to export merged coloured-shade tiff

[Rengifo Ortega]

Dear Markusthanks a lot. It partly did the trick.
When using those settings in r.out.gdal, as you suggested,  it did preserve the 
colors as you said.  But , it also creates a long palette of colors that makes 
the rendering in ArcGIS  very slow specially for large tiffs . On the other 
hand, the RGB as produced by r.out.tiff (GRASS 6.4)  get rendered faster. For 
the time being it is a vailable solution, specially for small  datasets. 
For large datasets I am going to stick to r.out.tiff OR a  give try to a pure 
gdal approach using the hsv_merge.py script create by frank warmedam as 
suggested in this siteA workflow for creating beautiful relief shaded dems

Just a quick question: is it really 7.0.0beta? Please consider to
update to 7.0.2 which comes with tons of important improvements.

So you followed
https://grass.osgeo.org/grass70/manuals/r.out.gdal.html#export-r,g,b-imagery-bands-in-geotiff-format-suitable-for-esri-software:

and the ESRI software not able to open the files? Which error message came up?


Probably it is opened but the colors are messed up? I can try later today. 
Anna

Re: [GRASS-user] Automatic extraction of valley

[Rengifo Ortega]

Dear Jean,
If I understand you correctly what you are looking for is to make a  swath 
profile along curved geomorphic features e.g botton valleys. I think  that if  
you want to this in  grass gis, it would be enough to  create a  mask using the 
the polygon you show in your picture and then extract that area using 
r.mapcalc. You also can use the geomorphons approach,  described by Vaclav, but 
you have to be careful with the parameters, since they will yield different 
results depending on your parameters.I would rather use gemorphons instead of 
r.param.scale, since it is scale independent.  If you want something more 
specific I suggest you to take a  look at this paper it might give some  ideas 
about the topic.

[GRASS-user] GRASS 7.0.0

[Rengifo Ortega]

Dear Grass users,
recently I installed GRASS 7.0.0 on ubuntu 14.04 (32 bits). When I tried to 
open  by typing  grass70 command I get the  following error message: python: 
can't open file '/usr/lib/grass70/gui/wxpython/gis_set.py': [Errno 2] No such 
file or directory
Received EXIT message from GUI.
GRASS is not started. Bye
 I also have  version 6.4.3 pefectly working from before, but I would like to 
migrate to Grass 70 as soon as posible. Any suggestions how to solve this issue?
thanks in advance..

Re: [GRASS-user] how to make radiometric correction of Aster level 1A image in GRASS GIS

[Rengifo Ortega]

 
Dear
Nikos first of all,
 thanks
a lot for your quick response !. I guess I  will have to install
grass70.  

Rengifo
Ortega:
 I have a ASTL1A image (HDF4), which I intend to use
to generate a DEM using the stereo pipeline, called AMES (NASA
software). 

Note, also, the manual states clearly:

 
ASP can only pro cess Level 1B satellite imagery
 
(http://byss.arc.nasa.gov/stereopipeline/binaries/asp_book-2.4.1.pdf,
 
Chapter 4, page 37). 

 Sofar
I understand  Aster Level 1B imagery is just  a derivative
from Aster Level 1A  imagery. See link below.
 
http://spatial-analyst.net/ILWIS/htm/ilwismen/import_aster_technical_information.htm


The
level 1A raw data are reconstructed, unprocessed instrument digital
counts. This product contains image data with geometric correction
coefficients and radiometric calibration coefficients appended but
not applied [...] 

 The
level 1B product contains radiometrically calibrated and
geometrically coregistered data for all channels. This product is
created by applying the radiometric and geometric coefficients to the
level 1A data [...]

 So,
I thought, If I can make the radiometric correction in GRASS GIS 
and eventually the geometrical correction, I would be able to use
this image in AMES as if it was a ASTL1B imagery. Please, correct me
if I am being to optimistic and understimate the work load of doing
so ...:-(  
 
After
all, the information needed to do this can be found in the metadata
file (.met) attached to the ASTL1A image.
 Greetings
Rengifo Ortega
