| 摘 要： | 针对普通电子地图中很难对地图要素进行三维量测的问题,提出了基于DEM的电子地图的概念。它实现了三维的DEM和二维的电子地图的垂直集成。两者优势互补,不仅极大地提高了电子地图的空间表现能力和量算水平,还大大地扩展了对DEM的应用潜力。探讨了用格网DEM与电子地图的集成方法,重点探讨了在基于格网DEM的电子地图上进行三维量算的数学模型。 |

| Abstract: | Aim at problem of difficult to 3D measure maps elements in ordinarily electronic maps,idea of electronic maps based on DEM is brought forward.The maps make 3D DEM and 2D electronic maps to vertically integrate,and to take advantage of each other,and to advance spatial representing map measure ability of electronic maps,and to strengthen application potential of DEM.Method of vertically integrating grid DEM and electronic maps is researched,and 3D measure models of electronic maps based on grid DEM is studied. |
