Hi Stefan,

Thank you. I did not know. That's great.

Cheers,
Frank

Hei Frank,

Did you try the “spatial” option in v.in.ogr (or the r-flag) (if your data is in a shape-file to start with):

https://grass.osgeo.org/grass74/manuals/v.in.ogr.html?

And is v.clip slower than v.overlay (that could be used as well)?

Cheers

Stefan

Hello Vero,

Thanks for your reply. It took almost one hour to extract my area (I guess because of topology). I do the same with Qgis from a shape in less than 10 minutes (but with several operations)... it's may be a bad idea to have a so heavy vector map in Grass...

Cheers,

Frank

    Check v.extract or v.clip

        Hello,

        What is the best and fast way to make a copy of a part of
        vector map
        (national) to get a smaller territory ? (partial copy).
        Thank you for your advice !

        Frank
