[Gvsig_english] Editing multipart polyline with Z and M coordinates

Hi Alberto.

The gvSIG core supports both Z and M coordinates. You can load a SHP 
with these coordinates, export it to Postgis and you will see how you 
are not going to loose information.

But your question is related to tools to editing M (or Z) and the 
management of the dynamic segmentation (supporting Linear Reference 
Systems). We are developing some of them for some internal projects but 
I don't know if these tools are going to be released in next gvSIG versions.

Regards.

Jorge.
