[GRASS-user] adaptive gaussian filter

[Jachym Cepicky]

Hi all,

I would like to ask, whether there is a code or extension, which would
apply gaussian filtering on raster data, but with varying sigma value
according to one of input raster maps?

I would like to blur raster but differently on different regions (e.g.
based on texture characteristics)

Thank you

Re: [GRASS-user] counting plants

Hi,

I was playing with this topic couple of years ago (about ten :-D) and
prepared some filters which worked quite well...

Anyway, best results I got with such type of data was: identify local
maximal values and count the pixels

Re: [GRASS-user] Linux Journal features GRASS GIS

[Jachym Cepicky]

Hi,

what about moving PERMANENT to .PERMANENT (hidden configuration mapset)

People, who want to know, can use it

People who don't care, don't see it

GRASS would move little bit to new users.

However, some of it's essence would be gone.

J

Dne 5.6.2013 09:08, Benjamin Ducke napsal(a):
 Dear All,
 
 This month's edition of the Amerian Linux Journal
 (www.linuxjournal.com) features an article on GRASS.
 
 Overall, I would say the article does a good job
 of introducing potential new users to GRASS.
 
 However, while reading it, I realised that two
 conceptual problems remain that new users might
 struggle with:
 
 1. The role of the PERMAMENT mapset remains
 hard to grasp (the article wrongly suggests that
 this should be the default mapset to log into).
 
 2. The GUI does not speak the same language as
 the CLI when it comes to the use of the terms
 map, layer and monitor.
 
 The first issue could be addressed by displaying
 a warning of the kind Do you really want to work
 in the PERMANENT mapset when a first-time login
 attempt is made.
 
 The second issue requires some consideration of
 how map and layer are used in different ways
 at the moment. Traditionally, a map is a GRASS
 raster or vector dataset. In the GUI, what used to
 be a monitor is now called Map Display, whereas
 what used to be maps is now called Map layers
 (and the associated window title is Layer Manager).
 Novice users might stumble over this when they
 discover the vector modules' layer= option and/or
 any single-input module's map= option.
 
 Also:
 - The window title Layer Manager is somewhat
 of a misnomer, since this is really the main window
 and does a lot more than just managing a layer list.
 
 - Using the location name as right-hand part of the
 Map Display window title suggests that there could be
 multiple locations per GRASS session (as there can be
 multiple Map Display windows), which is misleading
 (at least for languages that use left-to-right writing).
 
 To bring back consistency, some review of terminology
 across CLI and GUI seems in order. Since it seems to
 me that it is easiest to change some strings in the
 GUI, I would suggest something like this:
 
 Layer Manager = GRASS GIS - location (filename.gxw)
 
 Map Display x = GRASS GIS - location (Monitor x)
 
 Map layers = Maps
 
 Display x = Monitor x
 
 Best,
 
 Ben

 Location Info:
    extent -180,-90,180,90
    mapset PERMANENT
 you can import any grass vector data using v.in.ogr and display it in OL
 using d.vect
 For Listed GRASS modules:
 1. Type on search box on top for list and select a module and hit enter or
 click search
 2. you will get a menuForm of the selected GRASS module.
 3. Fill all the attributes and click run to execute the grass module.
 You can also run any grass command v.* or r.* using this webUI which is
 unlisted

 please test it

 Any comments, suggestions, BUGS are always welcomed..

Hi,

read README and readme.gipe files fist.

Than, you would have to get the GRASS sources as well (apt-get source
grass) and you will have to setup the proper variables at the beginning
of install_yanns_grass.sh file

than , you have to run the install_yanns_grass.sh file

you can find out, what the raster uses for coordinate system using
gdalinfo utility

you can also create new location according to the raster/vector map,
like

1) start grass in *any* location
2) run r.in.gdal location=NEW_LOCATION
3) switch to your new created NEW_LOCATION

Re: [GRASS-user] create a workplace (location mapset etc)_

[Jachym Cepicky]

hi.
you can make the raster (and vector) data accessable via UMN MapServer
directly, without any export need. UMN MapServer can read the data (via
gdal/ogr) and display the via WMS.

There is also another project, called pywms, which provides automatic
WMS Service based on GRASS Database. The Capabilities document for WMS
is created from GRASS Database on-the-fly, as well as maps.

So, only r.in.gdal would be need, r.out.gdal is actually no necessary.

 My god,I am crazying@@!

basically, any location can be considered as temp, because of after
deleting the whole directory, it is gone (uninstalled).

if you want to create temp location in a batch script, just prepare some
template location (with PERMANENT mapset and DEFULT_WIND and other
files)

than you can just copy this template under new name and so the temporary
location is created.

if you set the GRASS_BATCH_JOB env. variable, (shell script to be   
processed as batch job), the script will be performed automatically.

Re: [GRASS-user] Automatic Orthorectification

[Jachym Cepicky]

Hi,

the GCPs are located in each image at known locations, you can create
necessary files in a batch script:

 - you have to create the group for each image (i.group)
 - you have to set the target and ref files for the group (i.target)
 - you have to create the POINTS file - manually

try to rectify one image by hand and then see 
grassdata/LOCATION/MAPSET/group/GROUP/*

however, if the position of GCPs is unknown to you, I'm affraid, you
have to do it by hand

Re: [GRASS-user] r.water.outlet and SELECT WHERE Maximum

[Jachym Cepicky]

Hi,
achim píše v Út 03. 03. 2009 v 17:52 +0100:
 Hello,
 
 today I have two questions...
 
 No 1.
 r.water.outlet doesn't produce the hole outlet. I chose coordinates E
 and N from point coordinates. The point was converted from a raster-cell
 via r.to.vect. For illustration I attach a screenshot.

IMHO, this is caused by rough raster resolution. You have to click to
some other place in order to get outlet you ar looking for

 
 No 2.
 I'd like to select the raster-cell with the highest value. I converted
 the raster to points and tried to select with SELECT WHERE. How can I
 use an maximum-statement in it? I couldn't fix it out. Or is there
 another way? (I use the default db)

something like SELECT cat FROM points WHERE z = (SELECT max(z) FROM
points);

However, I'm afraid, this is not possible with DBF driver, you'll have
to convert the database e.g. into postgresql or sqlite

 Hi Jachym,
 
 How do I check this out?
 
 Ta, Jim

if you start osgeo command line, and there are programs like ogr2ogr,
gdalinfo, ogrinfo available, if gdalinfo --formats and ogrinfo --formats
do give you GRASS Raster/Vector (among others) and if they are checked
in the packages-selection screen of the installator[1] (look in Libs)

Re: [GRASS-user] face to DEM?

Hi,

you can try v.surf.rst as well

Vincent Bain píše v Ne 15. 02. 2009 v 10:32 +0100:
 Hello Adam,
 hope I understood what you mean to do. If I had to cope with your
 problem, I would import the source file as points, then run v.to.rast,
 and r.surf.nnbathy with the l interpolation method.
 The risk for this solution is the triangulation performed by
 r.surf.nnbathy be different from your source TIN...
 
 Good luck,
 Vincent.

  I imported them into grass like this:

  I can see the faces, and if I click on points around the edges I can

  I can't figure out how to generate a raster DEM from these faces.   
  Essentially I would like to know the approximate elevation at each  
  raster point inside the faces.
  I tried v.to.rast but then I get Column parameter missing
  For v.to.rast3 I get  Unable to get layer info for vector map
  I also tried v.extrude but I see all 0s (ie Number of areas: 0 etc.)
  
  Did I do something wrong on my import?  Did I miss some other way to  
  do the conversion?
  I want to be able to do some mapcalcs with the heights of an these  
  faces compared to another raster map, but I can't figure out how to  
  convert these faces to something that I can work with.
  
  Thanks much,

 the variation of temperature over a period of time as an animation
 (simulation). I hope to provide the output (simulation) in a web site so
 anyone can view the simulation as a Flash animation. Also the user is given

 view the output as a Flash simulation through that web site.
 Can i use GRASS to develop the above appliation? Does GRASS support data

 Hi,

 I wish to export a subset with something like:

 what other alternatives exist to make this. Is there a way to export
 the subset without using a intermediate map?


AFAIK, to create new vector layer with the region you want to export
is the best way. You can write a small script, which does the work for
you automatically [1].

Re: [GRASS-user] doubt about picture link

[Jachym Cepicky]

Hi,

well, you can always convert your database from DBF format to
PostgreSQL and use their BLOB type. Then you can store the images
directly to database.

If this is not what you are looking for, just add new column of type
STRING (varchar) to the database:

v.db.addcol map=your_vector column=image varchar(256)

then you can store the link directly.

Re: [GRASS-user] Speaking of starspan...

[Jachym Cepicky]

Hi,

nearly everybody would be interested, but nearly nobody has own time
for help. In case, nobody should write you directly, just have a look
at GRASS modules examples, they are IMHO very illustrative:

http://trac.osgeo.org/grass/browser/grass/trunk/doc/vector
http://trac.osgeo.org/grass/browser/grass/trunk/doc/raster

2008/8/1 Jonathan Greenberg [EMAIL PROTECTED]:
 We've updated/fixed/improved starspan over the past few months, and even
 began to create a grass interface for it:

 http://starspan.casil.ucdavis.edu/doku/doku.php?id=grass

 Unfortunately, our amazing programmer Carlos Rueda has left for greener
 pastures (congrats to Carlos on his new job!), so we were hoping to get some
 grass experts with a few hours on their hands to help finish a grass wrapper
 for starspan (and possibly have it included in a future grass release?)  If
 anyone is interested, send me an email.

 The main website is http://starspan.casil.ucdavis.edu

 Cheers!

Re: [GRASS-user] Open layers, Google maps/earth

[Jachym Cepicky]

hi,

OpenLayers is not a server, as well as google maps is not - they are
both javascript api

r.in.wms is (more or less) implementation of OGC Web Map Service [1]

If you want to get the map, which is displayed at
http://www.openlayers.org, you have to run r.in.wms like

r.in.wms mapserv=http://www2.dmsolutions.ca/cgi-bin/mswms_gmap
layers=bathymetry,land_fn,park,drain_fn,drainage,prov_bound,fedlimit,rail,road,popplace
format=image/png out=ol

(untested)

AFAIK there is no api for google maps yet, but it should be possible
to implement it

new gdal (1.5x) has support for OGC standards as well

jachym

2008/6/4 Richard Chirgwin [EMAIL PROTECTED]:
 All,

 I guess that r.in.wms works with servers like Openlayers and Google Maps (or
 even Google Earth); is there a quick tutorial explaining the parameters to
 use with these servers?

hi,
depends, what modules you used for data import

j

2008/5/19, Dinesh Kumar [EMAIL PROTECTED]:
 Hi,

 We have a code which uses grass data files. We import maps from other
 formats to grass and use these maps for our code. Recently we have
 updated Grass from version 5 to version 6. The files created with
 grass62 not working working with our code anymore.
 Does anyone knows if any changes have been made to the format of data
 files? If someone can point me to a document that describes Grass format
 for data files, it will be a great help.

 Hi!
 
 I have postgresql table with point data type column mypointloc. When i

 I have got message  WARNING: pg driver: column 'mypointloc', type 600

 Result table mynewtable have not x and y columns.


afaik you have to specify two new collumns of types (float or double),
for x and y coordinates.

grass does not support point column type used in potgresql

 
 How I have create vectors(points) objects from postgresql table?
 
 Is it possible to create new vectors(points) without creation new 
 attribute table?

yes, v.in.ascii should do the job

Re: [GRASS-user] MAPSET PERMANENT - permission denied

[Jachym Cepicky]

so, 
since I do not understand, what you are doing, I'll try to describe the
development procedure from the beginning:

1) download the source code
2) go to grass_trunk directory
3) download r.example and unpack to grass_trunk/raster directory 
4) ./configure ... ; make; sudo make install
5) go to grass_trunk/raster/r.example directory
6) You'll have to adjust MODULE_TOPDIR variable in Makefile to ../..
7) run make
8) go to grass_trunk
9) run sudo make install

10) start grass
11) r.example should be there (r.example --help is your friend)

BTW: Maybe we should move [rv].example from intevation server to osgeo
as well ?

Where to store it? grass_source/grass-examples ?

 I have set the Enviroment Variable by eval 'g.gisenv'

 i have following queries

 why is it so when i am using kunal as a mapset.
 
 2.
 i want to see the output of r.example which i added ..
 i will run  make install after make..my grass is also running ..where
 to go to check the output.
 
 Please suggest the way to handle the two problems.

 FWIW, the name of the GRASS variable for the database

 You can make the GRASS variables appear as shell

 command:
 
 eval `g.gisenv`
 
 After which, you can use the variables like e.g.:
 
 ls -l $GISDBASE/$LOCATION_NAME
 or:
 ls -l $GISDBASE/$LOCATION_NAME/$MAPSET
 etc.
 
 As for the error message in the subject: you must own
 the mapset
 directory in order to select it as the current mapset.
 The PERMANENT
 mapset will normally be owned by whoever originally

 You shouldn't use the PERMANENT mapset as the current
 mapset for daily
 use; create a new mapset instead. PERMANENT should be
 reserved for
 important data which should be readily available
 regardless of the
 current mapset.
 
 Until you get to the point of needing several mapsets
 in one location,
 you probably shouldn't have anything in the PERMANENT
 mapset except
 for the standard files (DEFAULT_WIND, PROJ_INFO,
 PROJ_UNITS).

no, it does not (afaik) support any point type in any database. even
postgis implements point type on it's own. you can also store the data
in postgis and import them to grass via v.in.ogr

adding support for the point type for postgresql should not be that
hard...

 you can also use `SELECT point FROM your_table|v.in.ascii out=points`
approach

Re: [GRASS-user] Not able to display Raster Image

You have to import raster data in GRASS internal database in order, to

you can do this with r.in.gdal command

if your data are not from spearfish60 region and with the same map
projection, then they should not be imported to the spearfish60
location. you should better create new location with map projection,
that corresponds with the projection of your map.

 You need to create a location whose projection matches the
 data you
 wish to import.
 
 Try using g.proj with the -c flag and the location= and
 georef=
 options to create a new location based upon the projection
 information
 in the file.
 
 You should then be able to import the file into that location
 with
 r.in.gdal. If desired, you can then re-project it to another
 location
 with r.proj.

 Hi
 
 I have a vector map where many lines have vertices. I wish to replace 
 all vertices with nodes, so I tried:
 v.split in=sewer_SS out=sewer_split ver=2
 
 The output is not what I expect in two respects:
 1.  The attribute table has been dropped.
 2.  I find that many lines are sharing the same cat, when cat should be 
 unique. Some of the lines with a common cat are not even connected to 
 the others.
 
 I am puzzled! Can anyone shed some light on what's going on here? I am

Re: [GRASS-user] Projection of dataset does not appear to match the current location!!!

Hi!!

Kunal Malik píše v Čt 14. 02. 2008 v 14:30 +0530:

 Projection of dataset does not  appear to match the current
 location!!!

this means, that your map is not in the same projection, as the
spearfish dataset is. you have to either:

* use -o flag for r.in.gdal, which will override the projection check
(use it only if you are sure, the map *is* in the same projection)

* create new location  mapset, which projection is the same, as the
file projection

* use the location= parameter in r.in.gdal, which will create new
location for you, with the projection according the raster file

* start GRASS with gui (grass62 -tcltk) and hit the Georeferenced file
button, which will create new location based on the projection values
from your tiff file

hope, this helps

Re: [GRASS-user] Projection of dataset does not appear to match the current location!!!

[Jachym Cepicky]

hi,

should work

so,

I do not know, if you are using GUI or CLI

in CLI:

g.list rast # gives you list of available raster maps
d.mon x0 # start grass monitor
d.rast your_map # displays raster file called your_map 

in GUI:

hit the Add raster layer button 

in new form, click at the Base raster layer button in GIS Manager and
choose your map in list of available maps

you can also write g.list rast in GRASS Output window and see the list
of available raster maps.

anyway, maybe now is good time to start to read some book ..?

  Projection of dataset does not  appear to match the current

 this means, that your map is not in the same projection, as
 the
 spearfish dataset is. you have to either:
 
 * use -o flag for r.in.gdal, which will override the
 projection check
 (use it only if you are sure, the map *is* in the same
 projection)
 
 * create new location  mapset, which projection is the same,
 as the
 file projection
 
 * use the location= parameter in r.in.gdal, which will create
 new
 location for you, with the projection according the raster
 file
 
 * start GRASS with gui (grass62 -tcltk) and hit the
 Georeferenced file
 button, which will create new location based on the projection
 values
 from your tiff file
 
 hope, this helps

Re: [GRASS-user] Use v.net.path to generate shortest path MATRIX?

[Jachym Cepicky]

Hi,

script would be the best. v.net.path can read start and end coordinates
from stdin:

echo 1 startx,starty,endx,endy|v.net.path in=network out=path

it should be possible, run with v.out.ascii output from your point file

for point in `v.out.ascii in=point`; do
  echo $point |grep|sed|awk|perl|python| v.net.path in=streams out=pathX
done

 Hello:
 
 Perhaps someone can direct me to the correct GRASS function(s)
 for accomplishing the following analysis (Ive read the documentation,
 am still unsure which, if any, GRASS tools will do the job):
 
 I have stream network data, in ArcMap line Shape File format, acquired from
 the USGS NHP2 dataset. The network data includes distance in Km.
 And, I have a point shape file containing the coordinates
 of lakes in the same region.
 
 I would like to generate an 'n x n' shortest path matrix between all of 
 the 'n' lakes using the
 stream network distances.
 
 It looks like v.net.path is the correct function to use, judging from 
 the manual page.
 My actual question: Is there a way to skip the command line input of 
 start/end points
 and use the point shape file as the source, so that a shortest path 
 matrix is created?
 
 I suppose I could write a script to do this, but only if necessary.
 
 Thanks for any suggestions!
 Rick Reeves
 
 Looks like I have to represent streams and lakes as separate vector layers

Re: [GRASS-user] How can I upload a screenshot (.png) in GRASS propaganda?

[Jachym Cepicky]

Hi,
you have to have login to GRASS Wiki (if you are refering to [1]. Then
you can upload screenshots.

If you want to add screenshot to GRASS Web Page [2], you need to have
access to SVN, which should be no problem. If you are developer, you
already have one, If not, you can get webpages-only access to do it.
However, Hamish did little reorganization of the screenshots page, maybe
better write him directly.

Re: [GRASS-user] Translator again

 Don't know abou the translation part but...
 
 Grass can import shapefiles and coverages as far as ArcView vectors
 goes (v.in.ogr command)
 It also supports the GRID rasters that you use in ArcVIEW, along with
 a bunch of other raster formats (r.in.gdal command).
 
 In other words, GRASS supports a lot of different formats using the
 GDAL and OGR libraries
 
 http://www.gdal.org/formats_list.html   -- raster supported formats
 http://www.gdal.org/ogr/ogr_formats.html   -- vector supported formats

Re: [GRASS-user] slope along defined section (e.g. road, stream,)

[Jachym Cepicky]

Hi,

Tim Michelsen píše v St 06. 02. 2008 v 17:22 +:
 Hello,
 I would like to get the slope of a defined section like a part of a river or
 a road.
 
 The only post dealing with such a idea was left unanswered:
 [GRASSLIST:7280] Hazard Assessment
 -
 http://thread.gmane.org/gmane.comp.gis.grass.user/8702
 
 My idea is the following:
 1) define a starting vector point and a end vector point of a stream or road
 section. 
 2) then run a module to calculate the slope along that section
 3) add the slope to the attribute table of the stream/road vector
 
 While point 1 and 2 are quite clear to me I would ask you for hints on how to
 calulate the slope as lined out in point 2.
 What I am looking into would be a slope version of d.measure...
 

This is imho not so easy, how it looks. While vector lines are kind of
discrete objects (from node to node is one line), slope changes
continuously. The attribute of the slope will always have to be some
average along the line. You can cut the line e.g. every 200m, to fit it
better.

Anyway, with v.drape you can fit your vector network to digital
elevation model. With v.to.db you can store the length of the line and
it's nodes coordinates to the database and slope is
length/(end_node_z-start_node_z), which can be performed with db.execute

What more: I just find out, that v.to.db has an option slope as well -
no need to calculate it manually :-)

  Hope, it helps

Jachym
 
 To have an idea on what one could like to do with the results:
 * Get a first estimate (based on DEM resolution) on hydraulic gradients in
 rivers
 * assess the risk of certain roads in mountainious regions
 
 Thanks in advance for your help.
 
 Kind regards,
 Timmie

 Hi Michael,
 
 I have started studying python more deeper for using it in pyWPS 

cool, we need more people :-) We have to move to WPS 1.0.0, so I'm
looking forward to see your code ;-)

 and
 for creating new Qgis modules (with QT).
 Just for knowing, is there any reason for using wxWindow instead of Qt
 for the new GUI?
 is it a matter of license?
 
 Thank you very much
 
 Luca

As others were mentioning before me, it was discussed several times ago.
When I started to experiment with Python GUI in GRASS, I took Gtk,
because of I simply liked it. Then Michael started to experiment, mainly
on Mac OS and wxWidgets seemed the best choice for him. Others were not
complaining. When we asked around, how the best approach should be, we
were told to use Java :-(

Maybe next GRASS GUI will be Qt :-) But the current (wxWidgets-based)
should be here at least as long, as the Tcl/Tk was.

Just my 2 cents

Re: [GRASS-user] GRASS QGIS

[Jachym Cepicky]

Hi,

once, I saw it by some guys from Germany. They read tons of data from
Oracle using Qgis.

Only thing you have to do is to compile ogr library with support for
oracle.

#1 download debian development tools
apt-get install dpkg-dev

#2 download the source code of GDAL library
apt-get source gdal

#3 go to gdal directory and adjust rules file in debian directory
cd gdal-1.4.2/debian
vim rules

[]
--with-ecw=yes \
--with-pg \
--with-ogdi \
--with-mysql \
--with-perl \
--with-ruby \
# add the oracle stuff here
--with-oci=/path/to/oracle/home
--with-oci-include=/path/to/Oracle/OCI/API/headers
--with-oci-lib=/same/for/libs
[]
 
#4 then you can run dpkg-build package and install missing packages,
until dpkg-buildpackage does not successfully build gdal package in ../
directory

#5 install generated packages with dpkg -i ../*gdal*deb

and it should work. you should be able to view oracle data from qgis, as
well as import them to grass
