摘要
随着数字化技术的发展,各行各业均在朝三维技术方向发展,地理信息行业也是如此。以数字高程模型DEM及数字正射影像DOM为基础,结合MapGIS软件的数据处理及三维渲染功能,联合构建了三维实景地形图,突破了传统二维地形图的局限性,提高了地形图的直观立体性、美观性和实用性。
With the development of digital technology, more and more industry transferd to 3D technology, as well as the geographic information industry. In this paper, a 3D real scene topographic map was constructed with a digital elevation model（DEM） and a digital orthophoto model（DOM）, combined with the MapGIS software, which broke the limitations of traditional 2D topographic maps and improved the aesthetics and practicality of the topographic map.
