Triangulate a volume of space. Let neurons be vertices of that graph. Every time you are at a certain point of space three or more (or four, for 3D space) neurons will be spiking depending on how close you are to them. That gives you absolute positioning. Also the ability to increase resolution for certain volumes of space.
