Hi Steve,
in mkgmap.jar (RouteArc) we use
private static int convertMeters(double l) {
// XXX: really a constant factor?
// this factor derived by looking at a variety
// of arcs in an IMG of Berlin; 1/4 of
// what used to be here
double factor = 3.28 / 16;
return (int) (l * factor);
}
In the display tool we use
// length should be in units of 16 feet
item.addText("length %d (%dm)", len, (int)(len * 16 /
3.25));
I guess it should always be either 3.28 or 3.25?
On the other hand, if the length is
somehow related to the unit foot, why
do I not see something like 0.3048?
Gerd
