- Title:
- Microcomputer Mapping of Digital Topographic Elements
- 摘要:
- 本文在采用网格地形高程数据结构的基础上，针对黄土高原地形破碎的特点，对小尺度（网格边长20米）研究区域的微机数字地形要素制图方法作了初步的探索，研制了适合于小尺度研究区域的数字地形要素微机制图系统软件，并通过小集水区研究实例绘制出了地面切割深度、坡度和坡向图。在此基础上，如再选择输入有关自然和社经的信息，可进行土壤侵蚀评价和土利地用评价等。
- Abstract:
- This paper is based on the raster format of digital elevation model, in light of the characteristics of breaking topography of the loess plateau to probe the method for the small raster formats (the each component 20 by 20 meters grid cell) of microcomputer mapping of digital topographic elements, and the mapping software is developed at the same time.The maps of surface cutting depth, slope and aspect of the cited small watershed in the study area are obtained.
