[GRASS-user] Merging point layers: Best practice?

Dear all

Trying to learn using GRASS in the ideal way: What would be best practice to merge multiple point-layers? Currently I can think of the two versions below. However, both seem to be a workaround.BTW: Does bounding-box definition in v.edit (“x1,y1,x2,y2”) mean lower left to upper right?

Regards, Patrick

#version1 (no features selected in my tests, probably due to bbox-definiiton)
v.in.ogr --overwrite dsn=“./POI” out=points1 layer=points2
v.in.ogr --overwrite dsn=“./POI” out=points2 layer=points1
v.info points2 # get extend of data
v.edit map=points1 tool=copy bgmap=points2 bbox=1074200,2484400,1297000,2834800 #use extend found manually

#version2
v.out.ascii in=post format=standard | v.edit tool=add map=service input=-

Maybe I'm missing the point, but isn't v.patch exactly doing that?
