Given the various possible ways of mapping sample points to lat/long 
coordinates, the least common denominator would probably be a triangle 
mesh, so what you'd actually ask for seems to boil down to another 
syntax for describing mesh/mesh2 objects. Somethng like

mesh_file {
   FILE_TYPE FILE_NAME
   [...]
}

(The same syntax could also be used for .obj files.)
