Nowadays, the land administration agencies have adopted a unified coordinate system to integrate the past data (such as questionnaire of cadastral map retest) with the existing data (such as road center of urban planning monument) to improve the accuracy and efficiency of surveys in traditional graphic cadastral regions and as a basis for multivariate applications.
In this study, first we collate past land resurveying boundary data. Then, measure and classify supplementary points of the past boundary data and present points at filed surveying. Third, use three-parameter transformation to join the supplementary points with integrated graphical cadastral map at office operation. At last, analyze the errors between the past boundary data and present points. The results show that the proposed method meets the accuracy specifications and can improve the operating efficiency.
