Sure, I meant current map view not the whole map. On zoom levels 4-5 WME map view is about 1 km² in size.dbraughlr wrote:Create buckets to divide the map into equal sized squares, say 1 km².
No doubt those buckets will reduce number of comparisons, but add complexity. And still there are will be thousands of comparisons and the check still will be very slow.dbraughlr wrote:For each segment on the map, determine which square(s) it crosses and add it (or a portion of it) to the bucket for those square(s).
So we're looking at quite slow and complex check here. But what's is the "goal"? Does this non-ground elevation affects TTS or routing?
