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