GeoVectorXYZ

GeoVectorXYZ[loc->{vX,vY,vZ}] represents a three-dimensional vector of Cartesian components vX, vY, vZ in an orthonormal frame parallel to the geocentric frame, at location loc.

GeoVectorXYZ[{loc1,loc2,…}->{vec1,vec2,…}] represents a collection of vectors veci at respective geo locations loci.

GeoVectorXYZ[{loc1->vec1,loc2->vec2,…}] represents the same collection of vectors.

GeoVectorXYZ[vec] represents a geo vector whose associated location has been implicitly specified.
