Re: [GRASS-user] Permission denied to access a mapset in Linux
Dear Glynn, When you said: GRASS won't allow you to select a mapset as the current mapset unless you are the owner of the mapset directory. How can I change the owner of a mapset directory?

You can access any mapset provided that you have the relevant permissions (read permission for files, read and execute permission for directories). GRASS won't allow you to select a mapset as the current mapset unless you are the owner of the mapset directory. If you just need to access maps from a particular mapset, you can add the mapset to the search path with g.mapset, or reference maps using fully-qualified names (map@mapset format). ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Re: [GRASS-user] Problems while running d.out.file
Hi Sorry to get back to this question again but I was not able to solve this. Ok 1- I have plotted my raster 2- I have added a command layer with this d.barscale bcolor=none at=0,90 3- If I use the Save display to graphic file functionality it works just fine. But If i try to set a smaller Width and Height: a) if I place barscale at 0,90 it gets cut b) If I place barscale at 0,0 it does not get cut but barscale gets over the image Is there any other suggestion on resizing PNG output without loosing image and barscale? Another question: when I launch a new Map Display window: Is it possible to define its size? Thanks Antonio Hamish wrote: Moritz wrote: I can confirm the issue (António, have you posted a bug report ?).

I'm not sure I fully understand the problem, but d.out.file has always worked well for me. the effect of making the width and height of the image is the same as dragging the xmonitor window bigger- the barscale and text is still the same size when viewed at 100% scale. when shrunk to fit on the screen in an image viewer it becomes tiny. You can make text and line widths bigger to compensate but really if you want things to scale well e.g. for a hi-res poster image, you should probably be using ps.map, not screen dumps of the Xmonitors, as the d.* modules were designed for. barscale and legend are placed as a percentage of the display frame, so at least their relative position should stay intact even if the frame gets bigger. if y'all think there's a bug please file a detailed ticket with the steps to reproduce using one of the standard datasets, and I'll look into it.

Re: [GRASS-user] Problems while running Export to PNG file
Hi (I have eddited the email subject) but when you export the map composition the overlays don't get the memo that they should be propor- tionately place themselves not simply as a fixed offset from the bottom-left corner. (? I'm not exactly sure how the overlay positioning works, but assume that's what's happening) I confirm. this is what it is happening. The quick work-around is for the user to use d.legend and d.scalebar as command layers in the main map layer wx gui (somewhat hidden under the add grid or vector labels icon) with manual command line controls. Then the legend or barscale gets rendered directly as part of map rendering, not overplotted as a movable overlay. Ok I was able to add a scale bar as command layer. When I export it the recoomended size it is plotted just fine and with a different size it addapted thje scale bar (it remained a bit bigger). Is it possilve to define Scalebar size (not just position)?

Re: [GRASS-user] Problems while running d.out.file

[GRASS-user] Running an external executable file from a Python Script
Greetings all, I have a python script from where I need to run an external binary (in Windows). This external binary (not developed by me) uses an input_parameter file to configure binary and get other parameters. The problem is that this binary requires that in my active folder I have my parameter file. Example: If I want to run this binary (outside GRASS Python Scripts) i open cmd, go to a folder where I have a parameter file (e.g. c:\delete (cd c:\delete)) Then I can run this binary as long as I have my parameter file in my active folder like this (c:\tool\training.exe). What I mean is that in my active folder I do not need to have my binary only my parameter file. My question is, when I'm running a GRASS python Script what is my active folder in order to place there my Parameter file? Or, is there any way to change my active folder while I'm running GRASS python Script? Hope I was clear enough in this email since this was unexpected for me.

AFAIK this is an osgeo4w issue. in the grass-starting routine there are following variables set in C:\OSGeo4W\etc\ini\grass set GISBASE=%OSGEO4W_ROOT%\apps\grass\grass-6.4.0svn set WINGISBASE=%OSGEO4W_ROOT%\apps\grass\grass-6.4.0svn set GRASS_SH=%OSGEO4W_ROOT%\apps\msys\bin\sh.exe set GRASS_WISH=%OSGEO4W_ROOT%\bin\wish.exe set GRASS_PYTHON=%OSGEO4W_ROOT%\bin\python.exe set GRASS_PROJSHARE=%OSGEO4W_ROOT%\share\proj set GRASS_HTML_BROWSER=%PROGRAMFILES%\Internet Explorer\iexplore.exe so this should be fixed there. please open a ticket there. best regards Helmut __ Information from ESET NOD32 Antivirus, version of virus signature database 5602 (20101108) __ The message was checked by ESET NOD32 Antivirus. http://www.eset.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] Re: self compile grass- msys
Hi there
I have sent a similar message to this
http://lists.osgeo.org/pipermail/grass-user/2010-September/057903.html
but to the wingrass mailing list.
Since there is no follow up on this subject in this mailing list I
wanted to know if anyone found any answer to this? Because I'm having
the same problem in winWXP 32. In the past I had this Windows GRASS
compilation and now, I decided to have it again but I'm having this problem:

What is missing in my installation? Because I have checked, and my
osgeo4W includes pdcurses-devel
Thanks

Hi Luisa I'm no expert in OSGEO4W but I believe you should 1- shut down Msys and reboot the PC 2- Try again I believe that you might have 1 problem: You don't have an include folder. I don't know how can you add it to your GRASS installation by using OSGEO4W.

Luisa, I believe Glynn and Martin can help you out on this but, I believe you will have to change grass/include/make (Platform.make ) in order to be adequate with your installation. Is this right Glynn? If so, shouldn't this be added to that Wiki? (if it makes sense, I volunteer for that) By the way, shoudl Luisa change Platform.make from include/make/Platform.make in source code or in the GRASS-desktop that she installed with OSGEO4W? __ Information from ESET NOD32 Antivirus, version of virus signature database 5196 (20100614) __ The message was checked by ESET NOD32 Antivirus. http://www.eset.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Re: Import GRIB files to GRASS
Hi all Well, since I'm only evaluating (for now) how to import GRIB's into GRASS, I wanted to test the r.region solution. Can anyone describe me what to do regarding that suggestion? Hamish, about the patch, I'm using GDAL1.7 so I cannot apply your patch. I'm going to reply on this in GDAL bug tracker. Thanks It is so interesting to see vastly different approaches to solve a similar problem. I'm downloading NOAA forecast data which is in GRIB format. I run the files through degrib and then parse the shape files with a C program using the shapelib libraries and create a new shape file which I import into GRASS with v.in.ogr. I plot the values with d.vect.thematic. The resulting maps can be viewed at: http://www.ars.usda.gov/npa/marc/heatstress That reminds me, I originally set up a location for each region with an eye forward on multithreading the map generation phases. I forgot the reason in the middle of the project and created several regions in one location. I had to revert back to a location for each region when I implemented multithreading but reduced the total map generation time from several hours to 15 minutes. :-) Randy __ Information from ESET NOD32 Antivirus, version of virus signature database 5189 (20100611) __ The message was checked by ESET NOD32 Antivirus. http://www.eset.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Re: [GRASS-user] Select random cells from map
Thanks Hamish I thought that random cells are retrieved from valid map cells. Or not? Antonio Hamish wrote: António wrote: I need to randomly select non-null cells from a given map. I tried r.random.cells but I cannot define a maximum number random cells and some selected random cells are not valid values in my map. is there any other function to randomly select cells from a raster?

(probably we/I should make a new wrapper script to do that automatically) or you might skip the last steps and just use v.random.cover's raster= option to sample the raster map directly. probably the best idea is to fix r.random's cover= option to loop until it has enough points. also if you will be doing a lot of geostats it is probably worth your while to learn about the GRASS-R interface: http://grass.osgeo.org/wiki/R_statistics ... then the world is open to you.

[GRASS-user] Using a polygon as a Mask
Greetings I have polygon that I want to use to define an for which I want to calculate some indicators (almost as a mask). Is it possible to use it directly in mapcalculator or do I have to convert it to RASTER and only then I can use it in mapcalculator as a mask?

Re: [GRASS-user] Using a polygon as a Mask
Thank you Christian What I am affraid is that when I convert Vector to RASTER I will obtain a mask that is not exacly the polygon in the boundaries of the polygon. For instance, if a pixel is cuttted by the polygons boundaries is it considered part odf the polygon or not?

Re: [GRASS-user] Landsat Stack import and export
Greetings Regarding the possibility of exporting an GROUp, using r.in.gldal, the groups are not listed in that menu. So the user cannot see the available groups. It's still processing but IO have one question: The processing bar restarted at least 3 times, what is happening? Because it file, now, it seems that it's not growing. Is it doing some file-check or something?

Is it possible using GRASS? To my knowledge no. Sure it is. Create a group in GRASS, export the group (r.out.gdal input=group_name) to a file format that supports multiple bands, e.g. GeoTIFF.
