I am writing maps for ZeppOS in JS using 256 by 256 raster Tiles. Using the official Wiki, I found a formula for determining the Tile on which an object with coordinates (lon, lat) is located
However, now I need to determine at which point on the Tile itself this object is located. Please tell me what formula I need to use for this?
