EPSG:23030 is a UTM projection, so yes it is supported. Mike David E. Reksten wrote: Take a look at: http://spatialreference.org/ref/epsg/23030/ http://spatialreference.org/ref/epsg/23030/proj4js/ .david On 13/02/2008, Ruben Pardo [EMAIL PROTECTED] wrote: hi, does proj4js support

This is how I reproject LL to UTM32: var destProj = new Proj4js.Proj(map.getProjection()); // Euref89 UTM32 var sourceProj = new Proj4js.Proj(EPSG:4326); // WGS84 LonLat var position = new OpenLayers.Geometry.Point(lon, lat); Proj4js.transform(sourceProj, destProj, position);

Hi all, I suppose that the method Bounds.transform(ProjA, ProjB) should transform the coordinates between differents EPSG codes. Now I was trying this: var p = bounds console.log(p) p = bounds.transform(new OpenLayers.Projection(EPSG: 900913), new

Hi, You need the proj4.js library to do reprojection in OpenLayers. https://svn.codehaus.org/mapbuilder/cscs/trunk/proj4js/lib Even with that I'm not sure EPSG:3003 will be supported. I recall that the author of proj4.js (Mike Adair) gave a list of supported projections on the OpenLayers

Ok, you're right 3003 isn't supported. But giving the Proj4 definition i have in my proj4 (java) epsg file, which is 3003 +proj=tmerc +lat_0=0 +lon_0=9 +k=0.999600 +x_0=150 +y_0=0 +ellps=intl +units=m +no_defs i could simply add my definition like this Proj4js.defs[EPSG:3003] =
