| Abstract: | Data matching is the key techniques in geospatial vector data integration and fusion.In this paper,spatial direction relation was described with direction relation matrix,calculation for spatial directions similarity in ordinary instance was discussed.Then an arithmetic flow for spatial vector data matching was put forward based on spatial directions similarity.At last,the area residential data in some representative were taken as example to test and analysis this arithmetic. |
