Zoom 5.16.2 free2/25/2024 ![]() ![]() Reproject the coordinates to the Spherical Mercator projection (from EPSG:4326 to EPSG:3857):.The following is identical to the well-known Web Mercator projection. By using this bound, the entire map becomes a (very large) square. Y goes from 0 (top edge is 85.0511 °N) to 2 zoom − 1 (bottom edge is 85.0511 °S) in a Mercator projectionįor the curious, the number 85.0511 is the result of arctan(sinh(π)).X goes from 0 (left edge is 180 °W) to 2 zoom − 1 (right edge is 180 ☎).In general, tiles belonging to the same row have equal height in degrees, but it decreases moving from the equator to the poles. (*) While the width (longitude) in degrees is constant, given a zoom level, for all tiles, this does not happen for the height. 18 is normally the maximum, but some tile servers might go beyond that. ![]() The zoom parameter is an integer between 0 (zoomed out) and 18 (zoomed in). transport/ zoom/ x/ y.pngįurther tilesets are available from various '3rd party' sources. (Historically several subdomains were often provided to get around browser limitations on the number of simultaneous HTTP connections to each host - such as a.tile, b.tile, c.tile - but this is less important with modern browsers.)
