基于3D产品制作三维地形数据模型

摘要

随着GIS和3D打印技术的革新与进步,打印三维地形图已具备可行的条件.基于已有的3D产品(DLG、DOM、DEM),使用现有的专业GIS软件,可以快速地制作三维地形图数据模型,配以色彩丰富、样式美观的三维地图符号,即可输出3D打印格式的三维地形数据模型,并选择合适的打印材料和打印机进行制作,可以丰富测绘产品的形式,促进3D打印地形图产业的迅速发展.%With the GIS and 3D printing technology innovation and progress, print three-dimensional topographic map already have viable conditions.Based on existing 3D product (DLG,DOM,DEM), using the existing professional GIS software, you can quickly create a three-dimensional topographic data model, with rich colors, beautiful style three-dimensional map symbols, you can output 3D print format 3D terrain model data, and select the appropriate printer and printed materials to be produced, can enrich in the form of surveying and mapping products, and promote the rapid development of 3D topographic map printing industry.
