[Gvsig_english] trouble with EPSG 2154 and 27561

[Bouillot Michel]

Hi, 

Thanks for this explanation. 

I find GVSIG very good but in France we have just changed of RS. We begin to have data in the 2 RS. 
The reprojection in the view would be very pactical ! 
Is there a hope for a such function in the futur ? 

Regards

Hi, 

In fact, you can't correctly represent data in different reference systems in the same View (without reporojecting, it have no sense). 

There are some software applications which applies automatically the reprojection, but it is not the case in gvSIG with vector layers. 

First of all, you have to select the correct RS for your View, and then load the data (the target RS you are going to work). 

Otherwise, you will see your data but in a incorrect situation. In other utm spindle, or displaced... 

If your data is in different RS, you will have to reproject it. Goprocessing tools->Data Conversion->Reproject; the layer in the not current projection to the current projection. 

Regards

Hello, 

I try to open in the same view one shp in EPSG 2154 and one SHP in EPSG 27561 but it don't match correctly. There is a problem with the X like a translation witch have a value who seems to be the difference between Greenwich and Paris meridian. 

How to correct this trouble ?
