Re: [OpenMap Users] Km -> LL/XY ?

Hi Fred,

Are you talking about coordinates that are represented in distance
units, or figuring out coordinates for a distance from a lat/lon point?

With the first, the coordinates are already projected, and you need to
use that projection definition to inverse project those coordinates
into decimal degree lat/lon coordinates. This code isn't something
you'd find in the OpenMap toolkit, you'd have to use a projection
library or something else to do it.

With the second, you can use the com.bbn.openmap.proj.GreatCircle class
to figure out coordinates that are a certain distance and azimuth from
another coordinate.

Hope this helps,

Don
