Abstract:	Aged map, surveying techniques, equipment,conservation method of map and coordinates system causes large differences between mapped area and registered area in cadastral survey. Re-survey is a way to solve this problem, but re-survey itself costs money and time. The ideal way is to narrowthe differences of area between mapped and registered to meet the related specification by just dealing with digitized cadastral map data. The Coordinate Vector Correction Method(CVCM) comes out under the motivation for dealing with digitized data.In this research, 10 experimental areas chose from the New Taipei City, Taichung City and Tainan City. All coordinates transferred to TWD97 datum by using affine transformation, and then adjusted them through CVCM. The analysis processed the data with CVCM, without CVCM and adding area-constraint. Results showedthe differences root mean squareimproved 38%comparing with area-constraint data. And areas of land parcels exceed the criteria of regulations roughly reduced 24%.
