With PostGIS, will migrating polygons into topologies using
toTopoGeom() provide any benefit with regard to point-in-polygon search?
I have a lot of data, roughly 15 sets of data. And, I am wondering if there would be a benefit to migrating all of it to topology. Currently, 100% of my queries are point-in-polygon. However, most of these queries could benefit from some kind of subdividing and simplification.
Take for instance the TIGER States file. If 100% of your workload included finding out what state a point was in, what would be the benefit of migrating those polygons into topologies? What I'm thinking is I can avoid overlaps in the event of simplification, and that syntactically I'm concerned only with which state a user in in.
I'm just not sure I understand topology and its benefit to polygons, but it's appealing to me to know that by defining the edge any form of movement of that edge results in maintaining two faces.
