I'm trying to decode mapbox vector tiles for use with SharpMap.

Does a tile know its position in the grid (x, y) and zoom level (z), or do I have to provide these values alongside with the vector tile?

  • What exactly is your question? These Vector tiles follow the same XYZ format: wiki.openstreetmap.org/wiki/Slippy_map_tilenames. Or are you asking something else? Dec 14, 2015 at 11:01
  • I want to know if the information of the position in the grid (x, y, z) value is encoded in the tile itself or if i have to provide x, y z value to properly decode the tile.

Version 2.0 of the vector tile specification clearifies this:

A Vector Tile SHOULD NOT contain information about its bounds and projection. The file format assumes that the decoder knows the bounds and projection of a Vector Tile before decoding it.
