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 
//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//
//v.out.ascii in=post format=standard | v.edit tool=add map=service
