Re: [Gwt-openlayers-users] Projection supported?

[<tin...@ar...>]

Hey Jon,

you have to include your projection in your javascript. You can find the code for the proj4js-projection on http://spatialreference.org/ref/epsg/32630/proj4js/

Proj4js.defs["EPSG:32630"] = "+proj=utm +zone=30 +ellps=WGS84 +datum=WGS84 +units=m +no_defs";

I you don't do this the conversion returns the coordinates you have put in.
This should solve yout problem.

regarda

Tino
