I think EPSG changed their minds last Feb This appears to be the new one: http://www.epsg-registry.org/export.htm?gml=urn:ogc:def:crs:EPSG::3857
EPSG:3785 shows isdeprecated true since Feb http://www.epsg-registry.org/export.htm?gml=urn:ogc:def:crs:EPSG::3785 Of course subject to further notice from EPSG? I don't know how many projects reflect the change though. This is pretty close: private Point Mercator(double lon, double lat) { /* spherical mercator for Google, VE, Yahoo etc * epsg:900913 R= 6378137 * x = longitude * y= R*ln(tan(pi/4 + latitude/2) */ double x = 6378137.0 * Math.PI / 180 * lon; double y = 6378137.0 * Math.Log(Math.Tan(Math.PI/180*(45+lat/2.0))); return new Point(x,y); } randy -----Original Message----- From: gdal-dev-boun...@lists.osgeo.org [mailto:gdal-dev-boun...@lists.osgeo.org] On Behalf Of Jean-Claude REPETTO Sent: Saturday, May 30, 2009 11:33 AM To: gdal-dev@lists.osgeo.org Cc: John Mitchell Subject: Re: [gdal-dev] converting epsg:4326 coordinates to spherical mercator (google maps) epsg:900913 John Mitchell a écrit : > Hi, > > If I have a lon,lat decimal degree epsg:4326 coordinate how do I convert > it to spherical mercator (google maps) epsg:900913? epsg:900913 is obsolete. The correct EPSG code is 3785. You can use cs2cs from the PROJ4 project to do the conversion.
