ABSTRACT:
A route calculation method allowing an optimized route to be drawn up by means of a calculator between a point α and a point β, consisting in using digitized data from at least a first and a second source, and consisting of (i) determining a plurality of alpha nodes (Nα), referenced in both the first and the second sources, and determining a first optimization value for each of the nodes; (ii) determining a plurality of beta nodes (Nβ), referenced in both the third and the second sources, and determining a first optimization value for each of the nodes; (iii) determining, for all the pairs of nodes Nα and Nβ, a second optimization value for each of the pairs of nodes (Nα, Nβ); (iv) determining, for the set of alpha-beta route, the optimum nodes between the points alpha and beta. The invention also relates to a device allowing implementation of the present method.
