【摘要】 数字地貌制图是地貌制图及其应用研究适应信息化发展的必然趋势。本文以昆明幅(G-48)地貌图为例,探讨在遥感与地理信息系统技术的支持下,中国1∶100万数字地貌制图的技术路线和方法,并结合昆明幅的具体地貌特征,重点分析数字地貌制图过程中的几个关键问题。分析结果表明:基于遥感与地理信息系统的数字地貌制图技术,不仅能提高地貌制图的效率,还能提高解译的质量和精度。更多还原

【Abstract】 Digital geomorphology is based on traditional methods of geomorphologic mapping and geographic information systems (GIS). Firstly, with an example of digital geomorphologic map, G-48, Kunming, this article formulates the technical routes and methods of 1:1000000 digital geomorphologic map in China based on RS and GIS. Then some issues in the geomorphologic mapping are discussed. It is shown that the geomorphologic mapping based on RS and GIS will improve the efficiency, quality and precision.更多还原
