Package tilecover computes the covering set of tiles for an orb.Geometry.
It is a a port of the nodejs library tile-cover
which is a port from Google's S2 library. The same set of tests pass.
poly := orb.Polygon{}
tiles, err := tilecover.Geometry(poly, zoom)
if err != nil {
// indicates a non-closed ring
}
for t := range tiles {
// do something with tile
}
// to merge up to as much as possible to a specific zoom
tiles = tilecover.MergeUp(tiles, 0)- tilecover - Node
