something along the lines of update data column when polygon table 2 inside polygon table 1
I have two data sets containing polygons Table 1 and Table 2 (similar to suburb boundaries Table 1 and individual land parcelsTable 2) I want to update data in Table 2 with data from Table 1 when the polygons in Table 2 are contained inside Table 1. The polygon boundaries are not necessarily 100% coincident

Hi,
the SpatialRelator should be suitable for that task. You can either specify INSIDE or INTERSECT for your test criteria.

in 2012 it is either within or contains, depending on the order of your filtering.
If u use intersect u might need to fliter out objects that marginally cross, overlap or touch and are (more ) outside of the objects that are suppose to contain. Unless that's what u want of course.
U can use compound testers for that.
Or even in the realtor expressionvalues using areacalculation etc.
Lots of options do the same thing.
In my case I'm working with points, to which I want to add the attributes of its containing polygon (each point has 0 or 1 containing polygons, and there are definitely several hundred points which have a containing polygon). However on running the Spatial Relator no attributes are added. I have also tried using the Spatial Filter and the PointOnAreaOverlay and neither of these add attributes either.

NeighborFinder could do the same.
Use the smaller areas as BASE and the larger as CANDIDATE.
Set maximum distance to 0 and do not treat polygons as line.
How do you select the smaller area and the largest ?
Thank you
