[gdal-dev] Does GDAL provide ring-level structural validation without GEOS topology validation?

[Even Rouault]

Denis,

nothing that I can immediately think of. OGRCircularString has a private 
method IsValidFast(). I guess you'd need that to be generalized (perhaps 
renamed to something like DoCheapValidation(), IsStructurallyValid(),  
IsWellFormed() or something like that, to not imply full validation). 
Contributions welcome as they say
