If you specify a point to OGRLayer::SetSpatialFilter() you should only
get back features that intersect that point.
Then do you have an idea how the "intersect" would behave between
a line string and a point? (I would expect TRUE if the point lies on
any of the line string legs,
FALSE otherwise) I'm asking since DEPARE layer may also contain line
string features besides
polygon features. (or shouldn't this happen at all?)
Yilmaz,
It will depend on how GEOS handles this, but I would generally expect it
to be difficult to define a point on a linestring except at nodes. If you
have a good sense of your precision needs, it might make sense to set the
spatial filter as a very small rectangle around the point of interest.
Best regards
