Abstract

After the Government issued Decision No. 83/2000/QD-TTg dated July 12, 2000, on the new national coordinate system and reference system VN2000 and with the Circular No. 973/2001/TT-TCĐC regarding the use of the National Reference System and Coordinate System, issued by General Department of Land Administration, the ministries, branches and localities of Vietnam have switched to using the new coordinate system VN2000 in the tasks of topographic and specialized mapping. However, in the Da Nang City, up to now, the entire construction planning maps and even maps are being made using the old coordinate system HN72, while other fields here, such as cadastral, traffic... have been applying the new coordinate system VN2000. The article points out the inadequacies in management when using planning maps that are not synchronized with other specialized maps and other documents. At the same time, it proposes the coordinate system transformation method of the old planning maps; and the application of the new coordinate system VN2000 in topographic surveying and managing planning maps within the Danang City.
