[Qgis-user] RES: Trouble with select by location between point and line layer

[João Carneiro]

Updating the information  below – 

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
