| Abstract: | Map projection transformation is a key research issue in cartography as well as in GIS. With the continuous updating and improvement of geographical data, effective handling of map projection transformation for geographic information is needed. In this paper, a map projection transformation module developed is presented based on object-oriented methods and discuss the advantages of the methods, with the design and implementation of the module explained in detail. In a VC-6.0 platform, a number of systems ha... |
