水电站工程生态环境影响评价中的坡度图制作

The Design of Indination Picture of Assessment of Ecological Environment Influence of Water-power Project

作者阐明了在地理信息系统软件(MAPGIS6.2)数字高程模型子系统下,根据不同的情况制作坡度图的方式,即把栅格数据扫描并转变为矢量数据后转为GRD格网数据生成坡度图和把外部高程数据直接转为MAPGIS明码格式 .DET数据而生成坡度图的制作过程.

This paper presents the method of design of indination picture in accordance with different conditions under the subsystem of digital super formula model of Geographical Information System software(MAPGIS 6.2). Namely, the indination picture is designed through transfering the grid digit after scan and translate into vector digit into GRD net digit and transfering exterior super formula digit into DET digital of MAPGIS format.
