[Gvsig_english] EPSG 27572

[Juan Lucas Dominguez Rubio]

Hello, Stéphane,
 
As you know, gvSIG Mobile does not reproject vector layers. It simply reprojects the GPS coordinates to the view's coordinate system so that the GPS cursor is placed properly on the map.
 
The first release of gvSIG Mobile is not using any library to perform this operation. All the calculation is in pure Java written by us, and currently the list of known coordinate systems cannot be extended by the user. If you want to add EPSG:27572 to that list, you have to compile the application yourself from the source code:
 
http://www.gvsig.gva.es/fileadmin/conselleria/images/Documentacion/descargas_mobile/fuentes/ws_gvsig_mobile_0.1.0_bn44.zip
 
and you will have to implement the body of this method:
 
public double[] epsg4326_to_epsg27572(double lon, double lat);
 
If you can make that method work on Windows Mobile, I will help you modify the code and you will have your extended version of gvSIG Mobile, compiled by you, of course.
 
I still don't know if future versions of gvSIG Mobile will support a wide range of coordinate systems.
 
Regards,

Hi ,

I'm testing gvSIG mobile 0.1 .

I can create a project with a current projection which is EPSG:27572
with gvSIG (PC version)

The projection EPSG:27572 doesn't seem to be available on the gvSig
mobile solution.
In the Application settings screen or in the Projet properties screen, I
can't select EPSG:27572

is it possible to have the EPSG:27572 projection for the gvSIG mobile
version?
How can I do?

thanks
