基于数字摄影测量的地理信息数据库更新方法设计
|
摘要
随着社会、经济和城市化的快速发展,科技在不断进步,原有的地理信息数据库更新方法已经不再适应发展的需要,但是保证地理信息数据的准确性对于我国各行各业的发展具有重要意义。基于此,本文首先对数字摄影测量做了简要概述,在此基础上对基于数字摄影测量的地理信息数据库更新方法进行探究,从中总结出地理信息数据库更新的三个技术特点:(1)关键数据动态更新与全部数据动态更新相协同;(2)数据级变量式更新;(3)实现多个地理信息数据库之间的联合变动、更新。
With the rapid development of society, economy and urbanization, science and technology are progressing constantly. The original updating methods of geographic information database no longer meet the needs of development, but ensuring the accuracy of geographic information data is of great significance to the development of all walks of life in China. Based on this, this paper firstly gives a brief overview of digital photogrammetry, and then explores the updating method of geographic information database based on digital photogrammetry, and summarizes three technical characteristics of geographic information database updating: 1) dynamic updating of key data and dynamic updating of all data; 2) variable updating of data level; 3) multiple geographic information. Joint changes and updates between databases.
