Abstract
- In this paper, we propose a new method to achieve automatic matching of multi-scale roads under the constraints of smaller scale data. The matching process is: Firstly, meshes are extracted from two different scales road data. Secondly, several basic meshes in the larger scale road network will be merged into a composite one which is matched with one mesh in the smaller scale road network, to complete the N∶1(N>1) and 1∶1 matching. Thirdly, meshes of the two different scale road data with M∶N(M>1,N>1) matching relationships will be matched. Finally, roads will be classified into two categories under the constraints of meshes: mesh boundary roads and mesh internal roads, and then matchings between the two scales meshes will be carried out within their own categories according to the matching relationships. The results show that roads of different scales will be more precisely matched using the proposed method.
