Most tiled web maps follow certain Google Maps conventions: Tiles are 256x256 pixels; At the outer most zoom level, 0, the entire world can be rendered in a single map tile. All tiles have the same size, usually 256x256 pixels. tileSize (required) specifies the size of the tile (of type google.maps.Size). ... Zoom level Resolution (meters / pixel) Map Scale (at 96 dpi) Width and Height of map (pixels) 0: 156,543.0339: This setting indicates that tiles are only created in the package and/or service down to level 19. (2 x 2) Zoom level 2 is 16 tiles. Exact length of the equator (according to Wikipedia) is 40075.016686 km in WGS-84.At zoom 0, one pixel would equal 156543.03 meters (assuming a tile size of 256 px): Maps Raster has 23 zoom levels, numbered 0 through 22. Resolution and Scale. Azure Maps provides raster and vector tiles for 23 zoom levels, numbered 0 through 22. but for Google Maps. Per 88ad's comment, the formula for the number of tiles is (2^zoom x 2^zoom). At every incremental zoom level the map doubles in size in each direction — each tile … When sharing a tile package or hosted tile layer from ArcMap to ArcGIS Online using the 'ArcGIS Online / Bing Maps / Google Maps' tiling scheme, the parameters for the level of detail can only be defined down to level 19. Similarly, zoom out by halving x and y (in the previous zoom level) . At the most zoomed out (level 0) the entire map is represented by a single 256 by 256 pixel square tile. There is one tile on the top of the pyramid, than 4 tiles, 16 tiles, etc. (4 x 4) Zoom level 3 is 64 tiles. Sizes must be rectangular though they need not be square. the size of a tile (in points) is 256/Math.pow(2,zoom) First calculate the southWest/northeast-points of the tile. (8 x 8) Zoom level 4 is 256 tiles (16 x 16) The x and y counts are doubled for each zoom level. The Azure Maps SDK's use tiles that have a size of 512 x 512 pixels for road maps, and smaller 256 x 256 pixels for satellite imagery. At zoom level 0, the entire world fits on a single tile: Zoom level 1 uses 4 tiles to render the world: a 2 x 2 square. Note that for maps consisting of one tile at zoom 0, the world size and base tile size … The world is divided into square tiles. Each tile is 256 pixels by 256 pixels. I also think it would be possible to calculate using this equation for whole earth: sigma(i^4) which i goes from 1 to 19 (zoom level) but it calculates for the whole world and gives tile numbers, I can later multiply it into average tile size (I have no idea about this value too). Tiles à la Google Maps Coordinates, Tile Bounds and Projection. (1 x 1) Zoom level 1 is 4 tiles. Zoom levels. Each zoom level doubles in both dimensions, so a single tile is replaced by 4 tiles when zooming in. Tile-level metadata (mandatory time-stamping [flight capture date]) Creation date and person; Modification date and person; Attribution; Image size in pixels; Raw size/uploaded size; Resolution/max zoom level according to Google's zoom levels; Bounds; Processing type (masking) Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. At zoom level 0, the entire world fits on a single tile: Zoom level 1 uses four tiles to render the world: a 2 x 2 square Assuming a basic google-map using mercator-projection and a tileSize of 256x256: The number of tiles on each(x-axis and y-axis) is Math.pow(2,zoom), so on zoom 0 the map is using 1 tile, on zoom 1 4 tiles, on zoom 2 16 tiles and so on. Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution. Zoom level 0 is 1 tile. Maps Vector has 23 zoom levels, numbered 0 through 22. The "world size" of a map using the base tile set at zoom level 0.
