全数字摄影测量方法在地理信息数据更新中的应用

摘要

Rapid development of society make a new requirement for surveying and mapping work. The contradiction between renewal of data and the data collection has become much more evident. Traditional data renewal method has the characteristics of highproduction cost and long renewal period. It can not meet the demand of high speed development of the society. It is very necessary to find a rapid and efficient data re- newal method. In this paper, renewal method and techniques of 3D digital product with the scale of 1: 10000 by using the digital photogrammetry method have been introduced. It can reduce the cost of data renewal and promote data renewal efficiency.%社会的飞速发展对测绘工作提出了新的要求，数据的现势性、数据采集的快速性矛盾逐渐突出，传统的数据更新方法生产成本高，更新周期长，已不能满足社会高速发展的需要。探索一条快速、高效的数据更新方法迫在眉睫。该文全面介绍了利用全数字摄影测量方法对已有1：1万3D数字产品进行更新的方法和技巧，在很大程度上缩短了数据更新周期，降低了数据更新的成本，提高了工作效率。
