| TMS Global Mercator Profile | |
| --------------------------- | |
| Functions necessary for generation of tiles in Spherical Mercator projection, | |
| EPSG:900913 (EPSG:gOOglE, Google Maps Global Mercator), EPSG:3785, OSGEO:41001. | |
| Such tiles are compatible with Google Maps, Bing Maps, Yahoo Maps, | |
| UK Ordnance Survey OpenSpace API, ... | |
| and you can overlay them on top of base maps of those web mapping applications. | |
| Pixel and tile coordinates are in TMS notation (origin [0,0] in bottom-left). | |
| What coordinate conversions do we need for TMS Global Mercator tiles:: | |
| LatLon <-> Meters <-> Pixels <-> Tile | |
| WGS84 coordinates Spherical Mercator Pixels in pyramid Tiles in pyramid | |
| lat/lon XY in metres XY pixels Z zoom XYZ from TMS | |
| EPSG:4326 EPSG:900913 | |
| .----. --------- -- TMS | |
| \ / | | /--------/ QuadTree | |
| ----- --------- /------------/ | |

| What is the coordinate extent of Earth in EPSG:900913? | |
| [-20037508.342789244, -20037508.342789244, 20037508.342789244, 20037508.342789244] | |
| Constant 20037508.342789244 comes from the circumference of the Earth in meters, | |
| which is 40 thousand kilometers, the coordinate origin is in the middle of extent. | |
| In fact you can calculate the constant as: 2 * math.pi * 6378137 / 2.0 | |
| $ echo 180 85 | gdaltransform -s_srs EPSG:4326 -t_srs EPSG:900913 | |
| Polar areas with abs(latitude) bigger then 85.05112878 are clipped off. | |
| What are zoom level constants (pixels/meter) for pyramid with EPSG:900913? | |
| whole region is on top of pyramid (zoom=0) covered by 256x256 pixels tile, | |
| every lower zoom level resolution is always divided by two | |
| initialResolution = 20037508.342789244 * 2 / 256 = 156543.03392804062 | |
| What is the difference between TMS and Google Maps/QuadTree tile name convention? | |
| The tile raster itself is the same (equal extent, projection, pixel size), | |
| there is just different identification of the same raster tile. | |
| Tiles in TMS are counted from [0,0] in the bottom-left corner, id is XYZ. | |
| Google placed the origin [0,0] to the top-left corner, reference is XYZ. | |
| Microsoft is referencing tiles by a QuadTree name, defined on the website: | |
| http://msdn2.microsoft.com/en-us/library/bb259689.aspx | |
| The lat/lon coordinates are using WGS84 datum, yeh? | |
| Yes, all lat/lon we are mentioning should use WGS84 Geodetic Datum. | |
| Well, the web clients like Google Maps are projecting those coordinates by | |
| Spherical Mercator, so in fact lat/lon coordinates on sphere are treated as if | |
| the were on the WGS84 ellipsoid. | |
| From MSDN documentation: | |
| To simplify the calculations, we use the spherical form of projection, not | |
| the ellipsoidal form. Since the projection is used only for map display, | |
| and not for displaying numeric coordinates, we don't need the extra precision | |
| of an ellipsoidal projection. The spherical projection causes approximately | |
| 0.33 percent scale distortion in the Y direction, which is not visually noticable. | |
| How do I create a raster in EPSG:900913 and convert coordinates with PROJ.4? | |
| You can use standard GIS tools like gdalwarp, cs2cs or gdaltransform. | |
| All of the tools supports -t_srs 'epsg:900913'. | |
| For other GIS programs check the exact definition of the projection: | |
| More info at http://spatialreference.org/ref/user/google-projection/ | |
| The same projection is degined as EPSG:3785. WKT definition is in the official | |
| EPSG database. | |
