gPolygonize doesn't work with some simple geometries.<br>
Here is an example:<br>
<br>
> LS = list(<br>
+ readWKT("LINESTRING (425963 576719, 425980 576703)"),<br>
+ readWKT("LINESTRING (425963 576719, 425882 577073)"),<br>
+ readWKT("LINESTRING (425980 576703, 426082 577072)"),<br>
+ readWKT("LINESTRING (425882 577073, 426082 577072)"),<br>
+ readWKT("LINESTRING (426138 577068, 426082 577072)"),<br>
+ readWKT("LINESTRING (426138 577068, 426420 577039)"),<br>
+ readWKT("LINESTRING (426420 577039, 426554 576990)"),<br>
+ readWKT("LINESTRING (426751 576924, 426776 576823)"),<br>
+ readWKT("LINESTRING (426751 576924, 426783 576919)"),<br>
+ readWKT("LINESTRING (426751 576924, 426714 576953)"),<br>
+ readWKT("LINESTRING (426776 576823, 426783 576919)"),<br>
+ readWKT("LINESTRING (426658 576966, 426554 576990)"),<br>
+ readWKT("LINESTRING (426658 576966, 426667 577031)"),<br>
+ readWKT("LINESTRING (426658 576966, 426714 576953)"),<br>
+ readWKT("LINESTRING (426667 577031, 426714 576953)")<br>
+ )<br>
> gPolygonize(LS)<br>
<br>
Traceback:<br>
1: .Call("rgeos_polygonize", .RGEOS_HANDLE, splist, id, p4s, getCutEdges, PACKAGE = "rgeos")<br>
2: gPolygonize(LS)<br>
Error in gPolygonize(LS) : caught access violation - continue with care<br>
<br>
I hope you can help me <br>
Kindest regards<br>
