comment How to determine intersection between geojson feature and given coordinates?
I guess using points (or centroids) is risky, because a cursor can cross a line somewhere between vertexes and the function won't find it.

comment How to determine intersection between geojson feature and given coordinates?
Thanks. I've used vector tiles with TileStache. Currently, I could get best performance with adding a utfgrid layer with feature id's in hitgrid. So when I hit a pixel with a specific feature in a grid, I add a corresponding feature from geojson to a map. But this way adds an overhead of loading utfgrid tiles (plus some server overhead to render this tiles). So I thought I can do this check directly in javascript without loading utfgrid tiles. quadtree looks interesting, but does it mean I have to cycle through it somehow on each mousemove to get a needed feature?

Sure, doesn't work anyway.

Maybe so, but removing -nln doesn't let me put -lco
