Hi all,<br>I am new here and to grass, so I have some questions about working with grass.</blockquote><div><br><br>Hello and welcome to the fun world of open source GRASS GIS!!! <br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
First,<br>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?
</blockquote><div><br>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.<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Next...<br>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</blockquote><div><br>v.patch should do the trick.<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Next.. <br>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?
</blockquote><div><br>v.category looks like it edits attributes.<br> </div>Sorry I cant be more definitive, but I'm working off of the old memory banks. =D<br><br><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
I would be happy if you could me give any answers.<br>Best regards
