| Abstract: | Combining the production of ‘the Series of World Map’ with the technique of GIS and computer network, the real-time tracking service of Xuelong Ship of Antarctic Expedition are firstly realized in November, 2004. In this article a few key questions are dissertated in detail, such as the theory of projection transformation, mapping of the map coordinates and screen coordinates, clipping of track line, of real-time track map, and the building up and applying of real-time track map on the net using visual subassembly. The concrete methods are put forward to settle these issues. |
