Hi
looking in Database PL/SQL PACKAGES you can find in schema GLOGOWNER
Package GPOINT
inside it the function:
"function estimate_distance(fromLat number, fromLon number, toLat number, toLon number) return number"

this function referring to java code in db (DbGPoint.calculateEstimateDistance), you could open (with TOAD or something similar) and check also the java code .

I haven't test if this function return same values returned by UI, but I imagine yes.

Regards
