[GRASS-user] graphically selecting multiple features
Hello, I'm new to GRASS, coming from an Arc* background, and often find that I'm approaching things from the wrong direction. I'm using GRASS 6.4 with the wxPython GUI. I would like to graphically select multiple features from a large vector file and edit an attribute of those features. (I have a poorly classified polygon shapefile of hydrology and want to separate the rivers from the lakes). How can I go about this. With v.what.vect I seem to be able to only edit one feature at a time. Any suggestions will be appreciated.

Re: [GRASS-user] graphically selecting multiple features
Hello Kurt, may it help you, I wrote a /very draft/ add-on that could help you : http://grass.osgeo.org/wiki/GRASS_AddOns#v.selmany The name of the module should remind you of old AI stuff... it's a shell script, so not working with grass70, and only tested with postgresql database connection (it will probably fail with dbf driver). Grass has to be launched in text mode (type grass64 -text from your shell prompt), and there must be an open monitor (d.mon). Good luck ! Vincent.
