--- template: example.html title: Canvas tiles example shortdesc: Renders tiles with coordinates for debugging. docs: > The black grid tiles are generated on the client with an HTML5 canvas. The displayed tile coordinates are OpenLayers tile coordinates. These increase from bottom to top, but standard XYZ tiling scheme coordinates increase from top to bottom. To calculate the `y` for a standard XYZ tile coordinate, use `-y - 1`. tags: "layers, openstreetmap, canvas" ---
