Great Circle Distance

This function will compute the great circle distance between two points on a sphere of uniform radius using the Vincenty formula. At minimum, four inputs are required: lat1, long1, lat2, long2. Optionally, a fifth parameter (r) can be specified. If this parameter isn't specified it's assumed to... Platforms: Matlab

GreatCirc is a tool for calculating Great Circle distances on the earth's surface, and plotting points and great circle paths on a world map. The "great circle path" is the shortest direct route between two points on the earth's surface. Because the earth is a globe, the shortest path between... Platforms: Windows

Computes the haversine (great circle) distance in metres between successive points on the surface of the Earth. These points are specified as vectors of latitudes and longitudes. Platforms: Matlab

Accepts a list of x and y coordinates. First, we find the smallest circumscribing polygon from this list (convhull). Finally, we use this polygon's coordinates to find the smallest circumscribing circle. We find the circle by minimizing the distance of the circle center to the polygon's... Platforms: Matlab

The Ejs Great Circles model displays the frictionless motion of a particle that is constrained to follow the surface of a perfect sphere. The sphere rotates underneath the particle, but since there is no friction, and the sphere is perfectly spherical, the motion of the particle is not influenced... Platforms: Mac
