Hello,
I am looking for some tips to split a polygon to its simplest linestrings. An example worth better than words : POLYGON((0 0, 0 1, 1 1, 1 0, 0 0)) Would become : MULTINLINESTRING((0 0, 0 1), (0 1, 1 1), (1 1, 1 0), (1 0, 0 0)) Every single linestring has to have two and only two points. Is there a way to do this with the existing postgis functions ? I found several ways to turn a polygon to a (multi)linestring but not to split it then into shortest linestrings. Thanks for any input.
