I reply to myself,

I mistook, if I append, I see a cat shift too. The fisrt cat of the second map is shift by one. It's strange no ?

Hi Stephan,

If I add two vector in a new one with :

v.patch -c input=map1,map2 out=map3

I notice the map3 first cat start at 2 instead of 1, so all cat are shifted by one. Do you have an idea of the reason ?

If I append my map1 with map2 :

v.patch -c -a input=map2 output=map1 --overwrite it works well

Thank you

Frank

Hi,

Try:
v.patch -a
https://grass.osgeo.org/grass76/manuals/v.patch.html

(assuming attribute tables are equal).

Cheers
Stefan

Subject: [GRASS-user] append data after a v.in.ascii import

Hello,

I wonder what is the best way to append a vector map and his attribute data 
created with v.in.ascii  ?

Thanks

Frank
