An Spatial Datum Acquisition Framework and Its Key Algorithms
Xia-jun Zhu, Huamao Gu · 2008
Spatial datum acquisition is one of fundamental components and main datum source of most GIS application systems. As a result, providing a universal framework for datum acquisition to satisfy the needs of those professional GIS applications is significant in GIS applications. The framework presented in this paper changes the traditional ways of datum acquisition, thus improving the efficiency greatly and reducing most potential man-made mistakes. Moreover, this paper also addressed those key algorithms employed in the framework and supplied their implementations.
