[postgis-devel] Issue 85 in postgis: ST_Distance crashes on Circular String

[codesite-noreply at google.com]

Comment #3 on issue 85 by mark.cav... at siriusit.co.uk: ST_Distance crashes  
on Circular String
http://code.google.com/p/postgis/issues/detail?id=85

Right, looking closer at the source code it's fairly obvious why this is  
falling over
- the complete set of distance2d_curve_*() and distance2d_*_curve()  
functions are
missing from measures.c!

Anyone know how to measure distance from a curve? Looking at
lwgeom_curvepolygon_area() in the same file, it appears as if we should  
segmentize
the curve into 32 linear sections and use that...


ATB,

Mark.
