Hi all,

I have made a supply chain map, which references some suppliers,
stores, warehouses...
They can be displayed or not by filtering with checkboxes.

It works pretty well so far but now I want to do something more
complex:

I want the user to be able to draw a line on the map , that line must
be closed (the beginning and the end at the same position), and then
the system has to display some information of markers located inside
the drawing.

The information to get is the number of items produced by a supplier
in one year, it is already present in the xml file that I use to
display markers.

The big difficulties for me are:
-Draw on the map.
-Get id of markers that are inside the drawing.

If anyone can help me with I would be really grateful.

Thanks in advance for your help.
Archi
