[gdal-dev] what does "Ring Self-intersection at or near point" really mean ?

[Thomas Gratier]

Hello,

I suppose it's similar to Postgis I know better. See this old post
http://www.davidgis.fr/blog/index.php?2007/05/11 to understand.
It seems to be related to OpenGIS Simple Features for
SQL<http://www.opengeospatial.org/standards/sfs>
