Subject: CoordinatesX 1.0.0 - Planetary Surface Coordinate Calculator for OS X
CoordinatesX 1.0.0 is an application that transforms geodetic and
Cartesian coordinates. It will make the conversions from Geodetic
latitude, longitude and heights to planet centered Cartesian coordinates
and vice versa. Works for various planetary ellipsoids, including user
defined ellipsoids.
Additionally, CoordinatesX will also compute long geodesic lines on the
ellipsoid. Given a starting latitude and longitude, a distance and a
direction, CoordinatesX will compute the location of the end point.
Also, it will compute the geodesic length and directions between two
points of known latitude and longitude. Baseline lengths and ellipsoidal
chord length computation are possible too.
Documentation of associated algorithms accompanies the application.
Coordinates is offered as freeware. May be distributed. Functions on PPC
under OSX 10.3 and later. Not recommended for anything running OS9 or below.
The current OS9 version is Coordinates 2.4.3, available on the archive
