Tiles à la Google Maps: Coordinates, Tile Bounds and ProjectionīTW: This demo is part of the documentation of MapTiler application. The site contains also a Python script doing the coordinates and bounds calculation offline. MapTiler use EPSG.IO database and has support for any coordinate system. This information is all you need for generating custom map tiles. MapTiler is Desktop app designed to turn large raster datasets into zoomable maps for your website. Boundaries are also displayed in projected Mercator coordinates (EPSG:900913, EPSG:3785) and in pixels for active zoom level. Whereever you click the longitude/latitude boundaries of the underlaying tile are displayed in WGS84 datum. The tool is excellent for fast debugging of tiling for particular area, because you can use the search for display the tiles of a given place.Ī transparent tile with correct coordinates is displayed for every original map tile by calling Google Chart API service. I think this mashup could be an excellent starting point for people who are interested in this subject, because it contains all the math what you need for overlaying your own geodata from external sources: it can be tiles pre-generated by MapTiler/GDAL2Tiles following the OSGeo TMS recommendations, it can be raster data from WMS servers probably cached by TileCache, or tiles from MSR MapCruncher etc. There is also a hosting service based on OpenMapTiles called MapTiler Cloud. Charts are relied upon to be as accurate and as up-to-date as possible by the vessels moving vast amounts of products to global ports each year. See the official coordinate system EPSG:3857. Electronic Navigational Chart (ENC) data are essential for safe maritime navigation and have multiple other uses in a wide range of enterprises. It uses coordinate system defined as EPSG:3857 or EPSG:900913. MapTiler Desktop can be used to convert data and maps into tiles. WGS84 / Simple Mercator - Spherical Mercator (unofficial deprecated OSGEO / Tile Map Service) Share on: T Q. The spherical Mercator tile profile compatible with Google, Bing, Yahoo Maps, MapQuest, OpenStreetMap, and mobile maps on iOS and Android. Choose from street & satellite maps of the entire world or create a custom map design. I prepared an online tool I was missing when I started to study how the tiling using Spherical Mercator runs in Google Maps, Virtual Earth, Yahoo Maps, OpenStreeMap and others… This tool can help you to understand how are the tiles referenced and how they are stitched together in the browser. Todays de-facto global standard is a Spherical Mercator projection because. Fulcrum supports XYZ tiles in the standard Web Mercator projection on both the web and. MapTiler makes it easy to build maps for your websites and mobile apps. Read more Spécifications techniques Systèmes dexploitation supportés Windows 7+ Windows Server 2008 R2 macOS 10.
