<br>
Does anyone know if MapServer supports WKT curves for feature geometries?<br>
I've tried a layer with the definition below but end up with the following error:<br>
<br>
msGEOSShapeFromWKT(): GEOS library error. Error reading WKT geometry "CIRCULARSTRING(1 5, 6 2, 7 3)". <br><br>
msGEOSError(): GEOS library error. ÉíKZ <br><br>
<br>
<br>
LAYER<br>
NAME "Curve"<br>
STATUS ON<br>
TYPE LINE<br>
FEATURE<br>
WKT "CIRCULARSTRING(1 5, 6 2, 7 3)"<br>
END<br>
CLASS<br>
STYLE<br>
COLOR 204 204 255<br>
WIDTH 3<br>
END<br>
END<br>
END<br>
<br>
Curve geometries seem to be supported in GDAL (see <a href="https://trac.osgeo.org/gdal/wiki/rfc49_curve_geometries">
https://trac.osgeo.org/gdal/wiki/rfc49_curve_geometries</a>) but not in GEOS (I'm using geos-3.4).
<br>
<br>
Any information welcome,<br>
Regards,<br>
