Abstract

The utilization of VN-2000 coordinate system in Vietnam is becoming practical and map data sharing standards. However, the GIS users in Vietnam is still expecting a unified protocol allowing for map processing and data sharing seamlessly and accurately. Currently, ArcGIS™ 10, one of the most robust GIS sofware, has made definitions of the geographic coordinate system GCS_VN_2000 for Vietnam. However, these are just the description! The capability of using map data from other sources together with VN-2000 is still a matter as the definition of the datum D_Vietnam_2000 and the transformation of datum from VN2000 to other datum and vise versa have not yet practically implemented in ArcGIS™. In this study, we propose a procedure to standardize map data to improve the interoperability in GIS practice and data sharing in a context of VN-2000 refference system.
