Simple question: How to transform a projected coordinate to lat/lon

[elkarel]

Hello, 

I'm very new to RGeo and to Ruby in general. However I've read this blog post about transformations and I came up with the following code:

factory_25831 = RGeo::Cartesian.factory(:srid => 25831)

point_25831 = factory_25831.point(505500.421875, 4699669.4375)

factory_4326 = RGeo::Geographic.spherical_factory(:srid => 4326)

point_4326 = RGeo::Feature.cast(point_25831, :factory => factory_4326, :project => true)

which gives me:

=> #<RGeo::Geographic::SphericalPointImpl:0xe35f6c "POINT (60.421875 90.0)">

But I should have obtained something like long: 3.0668887° / lat: 42.4493345°.

What am I doing wrong?

Thanks in advance.
