GeoVectorENU

GeoVectorENU[loc->{ve,vn}] represents a horizontal two-dimensional vector of components ve and vn in an orthonormal frame tangent to the Earth at geo location loc.

GeoVectorENU[loc->{ve,vn,vu}] represents a three-dimensional vector of horizontal components ve and vn, and vertical component vu at geo location loc. 

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

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

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