Hi all, I am new here and to grass, so I have some questions about working with grass.
Hello and welcome to the fun world of open source GRASS GIS!!! First,
I have some maps and one line, witch represents the boundary of area. And I need to trim my maps with this line (somethings like Clip by ESRI). Is it possible with Grass tools?
v.overlay will do a clip, inputting a line and a area as the "clipper". by selecting the "and" operator you will get the clipped lines. Next...
To my polygon map I want to add some polygons from other polygon map (Update, again like ESRI). I am not sure if v.patch is the best solution to get this
v.patch should do the trick. Next..
Can I edit the column header (name and type) of attribute table? I know another WIN software that can it do, but i am interested in GRASS now. Is it possible to remove some columns from the table with Grass?
v.category looks like it edits attributes. Sorry I cant be more definitive, but I'm working off of the old memory banks. =D I would be happy if you could me give any answers.
