Re: [GRASS-user] Re: GRASS Promotion Team
Hi, I am just commenting on the software. Inkscape is a vector graphics editor based on SVG (for single pages currently), similar to Illustrator or CorelDraw (although those may also support multipage documents). Inkscape, does not, per se produce large files if you stay with text and vector graphics. The files can only get large if you embed a lot of raster graphics. Embedding raster files can result in large files. Scribus is more a DTP software than a graphics editor, similar to InDesign. LaTeX is an entirely different beast with it's own strengths, best suited for writing scientific papers and articles. I don't think it is very well suited to design posters. For posters, flyers, clipart and vector graphics I would go with Inkscape, for multipage brochures I would go with Scribus and for manuals I would go with LaTeX. Btw: Inkscape can be used to produce and edit vector graphics that can later be embedded in Scribus (as SVG) and in LaTeX (I think best as PDF or PNG, or maybe also SVG in more recent versions).

Does Inkscape produce large files? I am asking because we already have a very nice poster [4], translated to several languages, which weights about 9MB for each language. Since it needs to be updated for every GRASS stable release, Martin proposed to rewrite it in LaTeX to share at least the graphics. If you could rewrite it for one language, I can use the LaTeX layout and catch up with other languages. I think the software we will use for promotional materials is to be discussed. For sure LaTeX will be the lightest and good to deal with localization but it will not gain many contributors. For smaller materials than the poster we might use other solutions. Chip has proposed Scribus [5]. Since my knowledge of Scribus is that it exists, I am going to read try and waiting for your opinions.

[GRASS-user] List of illegal characters for filenames
Hi I want to know if there is a GRASS GIS wiki with a list of illegal characters to be used in raster/vector names? Is there? Thanks Franz ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
[GRASS-user] Check if a raster map has any valid pixel
Greetings I have a python script where I need to check if an input raster map has any valid pixel (at least one pixel that is not null). How can I check this (easy and quick way?) in order to be integrated in my Script?

For rasters, the restrictions can be found in the source code for G_legal_filename(): http://trac.osgeo.org/grass/browser/grass/trunk/lib/gis/legal_name.c#L33 Specifically, any of the characters: / \ ' @ , = * plus space (32), DEL (127), control characters (0-31) and 8-bit characters (128-255). Furthermore, the characters: \ / : * ?| aren't allowed in filenames on Windows, so you can't use those if you want portability. The same restrictions apply to names of locations and mapsets. Currently, vector map names must be valid as an SQL table name, meaning that it can only contain letters, digits and underscore, and may not be an SQL keyword. -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

To confirm that, you could dump all data to a .sql file, create a new database in your project directory, then read in the sql file to re-create the database there. If you look in your project's PERMANENT directory you'll find a subdirectory for the database; there's probably something in there that's pointing in the old location and you can edit the file to point it in the proper location.

Re: [GRASS-user] Database question
Thanks. That is just what I needed! (There was still a little trick that the first time I used it I used the whole path to the old db, instead of just sqlite.db. The path failed, while just the file name worked) --Adam On Oct 25, 2010, at 11:30 AM, Achim Kisseler wrote: Hi, try v.db.reconnect.all or v.db.connect for single vector layers.
