# RE: [OpenMap Users] Distance between two LatLonPoint's?

Jeroen,

LatLonPoint.distance(LatLonPoint) will give you the distance between two
LatLonPoint objects in radians. You can convert it to what you like
using com.bbn.openmap.proj.Length. Here is an example.

LatLonPoint p1, p2;
......

This will give you the distance in kilometers between p1 and p2.

Hello,

Is there a method in OpenMap to calculate the distance between two
LatLonPoint's correctly (for example in kilometers)?

Thanks,

Jeroen

Subject: [OpenMap Users] Lat, Lon Display and CoordMouseMode

Hello,

I'm trying to get an understanding of how to most efficiently display
Lat, Lon of the current mouse position as it moves over the map. Looks
like CoordMouseMode plays an important part. I'd like to display Lat,
Lon somewhere on the GUI (not necessarily on the "info line". I admit
not fully understanding the architectural details of the various OM
parts. I'd appreciate any guidance.

Thanks.
