[GRASS-dev] getting cat value of node
Hi, I'm trying to figure out a way to find the cat value of a node. Using Vect_get_line_nodes() returns the ids of the initial and end node of a line. However, these ids are not the cat values of those nodes. I've looked into Vect_cat_get() but this function returns the first category value from the layer. Any ideas?

[GRASS-dev] selecting lines boundary-wise
Hi list, I'm trying to export the boundaries of a vector file, but would like to avoid duplication of common boundaries. It's easy to know which boundaries limit a given area, but how can I extract only one boundary. For example, area 1 has boundaries 6,7,9 while for area 2 these are 8,9. Is there a way to extract the lines of boundary 8 only for area 2 in order to avoid duplicating it? A comination of Vect_get_area_boundaries(Map,area,List) with something else?

Re: [GRASS-dev] sqlite and grass64
It seems to me that wxSQLite+ might be a good option to manage SQLite dbs. http://cfred.free.fr/wxsqliteplus.php Jaime On Tue, Apr 8, 2008 at 7:23 AM, Maciej Sieczka [EMAIL PROTECTED] wrote: Michael Barton pisze: SQLite Browser is a light-weight application that we could package with GRASS if we wanted to switch to SQLite before making wxPython the default GUI. It's nice, but my concern with it is that is appears not to have been updated for a couple years. I found one other free tool for the Mac to access SQLite databases (a couple others to manage them only). There seems to be more available for Windows and Linux. FWIW SQLite Administrator looks very interesting [1]. From their screendumps it resembles PgAdmin much. (Un)Related cool stuff I just found - SpatialLite [2]. It aims to be same thing for SQLite as PostGIS is for PostgreSQL. Maybe an inspiration for a new GRASS vector format someday?

[GRASS-dev] developing a GUI wxgrass-based
Hi, I was wondering if someone could give me some kind of orientation on how wxgrass accesses the list of raster/vector maps and both the tables and columns for the latter. I've gone through the code a couple of times, but I'm missing something. Thanks, Jaime ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
