Abstract：The 3D digital earth is adopted to realize the coordinate transformation by using Mercator projection mostly, which plays a key rolein the research of 3D map and military geographic information.In this paper, mathematics of Mercator projection is used ingeniously to put forward a transformation method of dragging dynamic coordination in digital terrain model by using the knowledge of the coordinate transformation.It is proved to be the effective that the algorithm is used in digitalterrainthrough the 3D rendering engine OSG simulation, and it is obviously raised in conversion precision and efficiency.
