Re: [GRASS-user] Using non-ASCII chartacters in r.reclass rules file
Hi Sorry for not being clear. When I try to display the legend, in Map Display Window, those characters are not displayed. Shall I add a print screen?

[GRASS-user] Re: How to extract one single contour.
Also, even when I zoom in to extract only one contour, the exported points are not always in order in the file, in a way that when I use it to plot in another program as a line, it connects the points in a wrong way. How can I export contours in an amenable way to use in other programs, such as Matlab, for instance? Thanks in advance. Marcello. Marcello Gorini wrote: Dear all, I am interested in extracting the longest -1,000 meter contour from a bathymetric DEM and to save it in a text file as points. By doing: r.contour in=my_dem out=contour levels=-1000 v.to.points in=contour out=contour_points dmax=my_resolution v.out.ascii in=contour_points out=contour_points.txt fs= dp=4 ... I get a text file with the contour points, however, it includes many different isolated contours, all with the same category (1). Since I need only the longest, I believe I need to separate the different contours, maybe assigning different categories somehow, then maybe updating the database with v.to.db using option=length and then v.db.select the longest contour. But I am not very used to working with vectors, so I don't know if that's the correct approach (nor how to accomplish it), so I would appreciate very much any help. Many thanks.

[GRASS-user] Grass on macos 10.7 aka Lion
Hi there, Latest William's binary (6.4.1) is working in Lion. In an upgraded machine there is no major problems to run it both with tcltk and wxpython. In a fresh installation, I got problems to point to the correct GISBASE directory, the terminal ended in the text gui and once I pointed to where grass data was, it starts with the following warnings: CFURLCreateWithString was passed this invalid URL string: '/System/Library/CoreServices/CommonCocoaPanels.bundle' (a file system path instead of an URL string). The URL created will not work with most file URL functions. CFURLCreateWithFileSystemPath or CFURLCreateWithFileSystemPathRelativeToBase should be used instead. wish warning: Wish[3284] Error: kCGErrorInvalidConnection: CGSGetWindowTags: Invalid connection Aug 1 19:04:51 vpn1-22.vpn.uv.es Wish[3284] Error: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Error in r.basin

Please could someone point me in the right direction ?

Re: [GRASS-user] Error in r.basin
Hi,
2011/8/1 Rosca Bogdan ros...@gmail.com:
grass.run_command('r.stream.extract', elevation =
r_elevation, accumulation = r_accumulation, threshold = th,
d8cut = 'infinity', mexp = 0, stream_rast = r_stream_e,
stream_vect = v_stream_e, direction = r_drainage_e, flags
='-o')
replace `flags = '-o'` with `overwrite = True`

This error comes from G_legal_filename():

return -1;
}
It appears that an invalid (and non-printable) character has crept in
to the value of the output= option.
Unfortunately, I don't have any ideas as to how to track this down.
How is the command being entered? In QGIS? the wxGUI? bash? cmd.exe?
If it's QGIS, I can only suggest taking it up with the QGIS
developers. If you can reproduce the error within GRASS itself, please
provide details.

When I try to display the legend, in Map Display Window, those characters are not displayed. Shall I add a print screen? You'll need to select a font which has those characters (I don't think that the default stroke fonts have accented characters), and also select the correct encoding (presumably either ISO-8859-1 or UTF-8). AFAICT, this has to be done globally, in the preferences. There doesn't appear to be a way to set the font or encoding for an individual layer. -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
