摘要
为了解决大比例尺GIS系统数据输入中存在的效率与精度较低的问题,采用面向GIS的大比例尺数字测图方法,介绍了几种数字测图的方法,有全站仪数字测图法、摄影测量数字测图法、机载激光扫描测图系统、机动测图系统,并总结了为满足GIS的数据要求在数据采集和数据处理阶段应当要注意的问题,以满足面向GIS大比例尺测图系统对数据准确性及现势性的要求。
To solve the problem of low efficiency and accuracy which exist at the data input of the large scale GIS system, the large scale digital mapping for GIS is used. This paper introduces several digital mapping methods, such as total station digital mapping, photogrammetry digital mapping, airborne laser scanner surveying system, mobile surveying system, and summarizes the problems in data collection and data processing stages which should be noted to meet the GIS data, in order to meet the requirements of the large scale digital mapping system for GIS to the accuracy and the.real-timing of data.
