I have a vector of a lake shoreline that is a series of connected line
segments that close in on each other to form a graphic polygon, not a true
polygon. Each line segment has several attributes, including a unique ID. I
converted the segments into a polygon, or boundary vector type, using
v.build.polylines. My problem is that none of the attributes exist in my new
polygon. When queried, I get the map name, mapset, feature type, and area,
but none of the attributes that previously existed in the individual
segments. Is there a way to attach the attributes of the old line segments
to the new polygon?
I thought that v.db.connect might help, but as there are no cat numbers or
IDs associated with the new boundary feature, so this wouldn't work.
Any ideas?
