A Study on Method of Map Conflation Based on Topological Relationship


Article Preview

A new approach for vector spatial data Fusion based on Topological Relationship is presented. The constraints in map conflation are first derived, and the coordinates displacements of the conflated objects are then obtained by topological correlation computation. The results of the map conflation test show that the proposed method has a high precision and better ability to maintain the characteristics of the conflated objects compared with the exist methods.
