[OpenLayers-Users] projection problem proj4js

[Robert Sanson]

Hi Karsten
 
This code works for me:
 
var src = new OpenLayers.Projection('EPSG:4326');
var dest = new OpenLayers.Projection('EPSG:2193');
latitude = document.getElementById('lat').value;
longitude = document.getElementById('llong').value;
var markergeom = new OpenLayers.Geometry.Point(longitude,latitude);
//now in-place re-projection
OpenLayers.Projection.transform(markergeom, src, dest); 
gpsx = markergeom.x;
gpsy = markergeom.y;
alert(alert('coordinates transformed:'+gpsx.toString()+','+gpsy.toString());
regards,
 
Robert Sanson

Thanks, now I do not get an error any more with this code:

var mapcenter = new OpenLayers.LonLat(-122.30785315739, 47.638080437239);
Proj4js.defs["EPSG:102003"] = "+proj=aea +lat_1=29.5 +lat_2=45.5 +lat_0=37.5 +lon_0=-96 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs";
var source = new OpenLayers.Projection("EPSG:4326");   
var dest = new OpenLayers.Projection("EPSG:102003");                                          
OpenLayers.Projection.transform(mapcenter, source, dest);
alert('coordinates transformed:'+mapcenter.toString());

However the coordinates are the same as the input values (-122.30785315739, 47.638080437239) and not transformed. 
What is still wrong ?
