A tolerance value would probably be needed in the general
case.
Have you tested with horizontal or vertical lines?

I have checked that select by location only selects the points that are
snapped to a vertice of a sg_line, but not snapped to segments. Is this
working as expected, or do we have a bug here?

*Assunto:* Trouble with select by location between point and line layer

Hello,

Has anyone had the following problems?

I am trying to detect topological problems in my data between two
classes called sg_point and sg_line. Our topological rule is that
sg_point MUST be snapped to sg_line.

I imagine that the best way to do this is by using “Select By Location”
and select all points that intersect the line. Unfortunately this does
not work, and neither does trying the opposite selection. Trying to
select all the points that don’t intersect the line gives me 100% of the
points even if there were some points that were correctly snapped to the
line beforehand.

I have not managed to select only the points that don’t intersect the
line or only the points that do intersect the line.

What am I doing wrong?

Thanks for any  help.

Best regards,

João Carneiro
