I'd like to be able to detect all line loops that are not closed, but where one end of the line loops around and terminates on another line (a lasso). Querying a table containing several of these returns no ST_IsClosed=true, or ST_IsValid=false, or ST_IsSimple=false. Ultimately, I'd like to split the original loop into a line segment = two loop halves.
Thanks In Advance.
