We also know that the web mercator extent is a square and its bounds are -PI * 6378137, PI * 6378137. With the above conventions, we know that at zoom level 1, the world is divided into 4 tiles with the coordinates depicted below.

Each zoom level doubles in both dimensions, so a single tile is replaced by 4 tiles when zooming in.

At the outer most zoom level, 0, the entire world can be rendered in a single map tile.

Most tiled web maps follow certain Google Maps conventions: Tile(Point and Zoom) to Web Mercator Coordinatesīefore diving into the simple math of calculating the web mercator coordinates, we need to understand a little more about tiled web maps and the parameters of the getTileUrl function we will write.

Convert point into web mercator coordinates.

There are two primary steps to creating the getTileUrl function: Servicio WMS de la información geotectónica de Sudamérica a escala 1:5.000.000. j 2017 In Qgis load in the Bing WMS server and your shapefiles. WMS Geoetectónico de Sudamérica Escala 1:5.000.000. WebHola a todosEste video es para saber como aadir una capa de cualquier mapa. Your getTileUrl is the option required to enable a WMS layer in Google Maps and how we create that tile URL must follow the WMS standard discussed above. Servicio WMS que expone todas las capas de información geográfica del Sistema de Información Geoambiental del SEGEMAR. Now that we have a basic understanding how the HTTP request to retrieve imagery from a WMS, we can begin exploring the interface Google Maps exposes for its map types, specifically the and. It rose to prominence when Google Maps adopted it in 2005. Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator or WGS 84/Pseudo-Mercator is a constiant of the Mercator projection and is the de facto standard for Web mapping applications. In the above request we are using EPSG:3857, also known as web mercator.

It is important to note that the coordinates for the BBOX parameter must be in the coordinate reference system specified by the spatial reference system(SRS).
