浅析数字地形测量中的野外数据采集

Analysis on data collection in digital landform survey

大比例尺数字地形测量中,野外数据的采集非常关键,针对野外作业时出现的一些问题,从数字高程模型的建立,浅谈内外业一体化数字地形测量方法中野外数据采集时应注意的几个问题,并采用陕西眉县小法仪镇1:1000数字地形测量实例图进行图形对照说明。

In the great-scale measurement,the field data collection is the key.This article has preliminarily discussed some problems in the field data collection of the integration of indoor and field digital terrain measurement,and choices the example map of digital terrain measurement of Xiaofa Town in the scale of 1：1000 to illuminate the theme.
