How to integrate and implement these two maps into a coordinate datum is a very important topic. Numerical area adapts control points directly with coordinate transformation in order to reach the goal. Digital map does not contain coordinate systems such as UTM, TM3, TM2, yet it includes errors in measurement, graph, scaling coefficeient of sheets, and historial map and graph transformation after division and combination. Except for those with cadastre re-measured, most digital maps in different counties and cities can not correctly integrate with seamless joint maps and large scale topographic maps. It is difficult enough to integrate a correct seamless point map in the same sector, not to mention using control points with coordinate transformation to correctly integrate with 1/1000 large scale topographic map. This study presented a model for overlay analysis in cadastral map and urban planning topographic map, using block as an unit and measuring real-time block status with virtual base stations RTK. Using the real-time reliable measrements as the coordinate transformation common points in order to eliminate partial distorsion after digitalization of cadastral maps. Furthermore; mapping the cadastral map boundary coordinate system from digital maps to TWD97 TM2 coordinate system measured in real-time to improve the overlay problems created from force integeration of coordinate transformation in cadastral map and urban planning topographic map. This research can amend the overlay problem in urban planning topographic maps and cadastral maps, and solve the overlay discrepancy in public urban planning mounment and cadastral maps.
