It seems that there a kind of offset. GeoJSON is a data-interchange format for a variety of geographic data structures. This on-line tool allows you to insert value pairs of geographic coordinates and transform them to different coordinate system or cartographic projection. Spherical Mercator has an official designation of EPSG:3857. - EPSG updates mailing list that EPSG:3785 will be added to version 6. 4648448965). For further illustration here is the EPSG structure for WGS 84, a commonly used geographic Coordinate Reference System: Evidently, many EPSG codes together make up the WGS84 coordinate system. WGS84 comprises a standard coordinate frame for the Earth, a datum/reference ellipsoid for raw altitude data, and a gravitational equipotential surface (the geoid) that defines the nominal sea level. A spatial reference system defines a specific map projection, as well as transformations between different spatial reference systems.

StyleFunction(feature, resolution) which returns an array of two styles. 89Mb) T2K Pro integrates the rich world of GIS datasets and transfers your Geographic information data into Google earth. ## Datum Conversion ## This app can also transform coordinates within EPSG , ESRI, IAU2000 references from online database. The latest revision is WGS 84 (dating from 1984 and last revised in 2004), which will be valid up to about 2010. The WGS84 CRS has become a global standard for latitude and longitude positions, such as those captured with GPS devices. IOGP is planning for the EPSG Dataset to adopt the recent changes made to the ISO 19111 data model to describe dynamic coordinate reference systems and datum ensembles. Frank Warmerdam, OSGeo, FWTools. The GeoTIFF format identifies geodetic datums primary by reference to EPSG datum identifiers.
