WebBTW, I'm still hopeful that a spherical-area-weighted centroid similar to the above will work. Imagine each polygon being given a 3D volume by adding a vertex at the sphere's origin. Then suspend the sphere by an invisible string connected to its origin and find a stable equilibrium. The centroid is the bottommost point (it's the projection of ... Weba = areaint (lat,lon) calculates the surface area of the polygon with geographic vertices lat and lon. This syntax references the coordinates to a unit sphere and returns a as the fraction of the sphere that the polygon covers. example a = areaint (lat,lon,ellipsoid) specifies the reference ellipsoid for the vertices.

To define a spherical coordinate system, one must choose two orthogonal directions, the zenith and the azimuth reference, and an origin point in space. These choices determine a reference plane that contains the origin and is perpendicular to the zenith. The spherical coordinates of a point P are then defined as follows: • The radius or radial distance is the Euclidean distance from the origin O to P.
