how to submit a ROI defined by dBox?

[Eduardo Patto Kanegae]

Hi folks,

I'm using dBox as my MapServer CGI front end and have enabled draw area tool.

Now I'd like to submit the points defined by area tool and then save
the area as a polygon inside a PostGIS database.

Have someone done something similar? How does dBox handle this area?
As image coordinates? Or as UTM coordinates?

best
