Description
Hi, I've noticed that when I select points within a polygon with a popular GIS (debateable) I have a higher hitrate than when doing the same in QGIS. After investigating the differences I found that with complex polygons - see attached images (The layer used was the UK's Ordinance and Survey's Master Map) points were ignored by QGIS and not by the other. I thought I'd take the time to let you know.
Cheers
Francois

Here we see Qgis perform a select within and misses some points

Here we see QGis perform a select within that works
Note:
See TracTickets
for help on using tickets.
Here we see another GIS where it uses the same layer and selects points fine
