The user can then represent the coordinates of sites of a polylist object as background map, using the option carte included in all interactive functions of GeoXp.

It returns a matrix of numeric values with 2 columns (x and y coordinates of the vertices of the polygons) where polygons are seperated from each other by 3 rows of NaN.
