I have a PostGIS database with a very large amount of geometries (circles), most of them overlapping. I'm trying to come up with a way to find the nearest point (from your current location) that is not within any of these circles.
Is this possible with a direct query?
So far I thought of a fishnet approach of 1x1 km cells that check for overlap with any of these circles. This works, but is not very accurate.
