Remove duplicate lines from vector map.
Remove duplicate lines of given types from vector map. Duplicate lines may be optionally written to error map. Input map must be opened on level 2 for update. Categories are merged.
Map | vector map where duplicate lines will be deleted |
type | type of line to be delete |
Err | vector map where duplicate lines will be written or NULL |
