[OpenLayers-Users] Transform Points Help

[Riaan Lombaard]

Hi,

Thanks for the advice.

I am looking at using proj4js.

But it seems like GDA94 is not supported by them. I might be mistaken but look at "proj4js\lib\defs" directory and you will  not find EPSG4283 .

Hi Riaan,

  In the console, if you inspect OpenLayers.Projections.transforms, you'll see which projection codes are natively supported in OpenLayers.  If yours is not there, then you need to include the Proj4js library and add the ones you want :

Hi,

I need some transformation advice.

Running this script in Firebug.
"
var point = new OpenLayers.Geometry.Point(128.627103622948, -15.8249150838119);
var point_transformed = point.transform(new OpenLayers.Projection("EPSG:4283"), new OpenLayers.Projection("EPSG:4269"));

console.log(point);
console.log(point_transformed)
"

What happens is the data I am getting is from `GDA94 (SRID 4283)` and I need convert it to ` WGS84 (SRID 4326)` for the map base layer I am using ` http://vmap0.tiles.osgeo.org/wms/vmap0`

But looking at the example it does not seem to convert anything, the x,y stay's the same?
What am I missing?

Riaan
