信息化测绘地形图产品生产工艺研究

Implementation of topographic mapping production processes in informationization surveying

经过模拟测绘、数字化测绘的发展,测绘正向信息化测绘的道路迈进。本文从国家1∶50000地形图更新项目需求出发,结合信息化测绘体系下产品更新生产的要求,以地形图产品生产为例,全面介绍数据库驱动下的两库一体产品生产技术体系以及基于增量的数据、产品动态更新技术方案,旨在为信息化测绘体系下的产品更新与生产提供新思路、新方法。本文形成的技术思想已经成功应用在国家1∶50000地形图实际生产项目中,在各省测绘局得到了广泛应用。

Informationization surveying is the new era after the digitalized surveying and simulating surveying. Strong demand of GIS services from the community is a challenge to this informationization sur- veying. How to provide the high quality, strong currency GIS products and diversity of services is impor- tant of the informationization surveying. This study described the core technology of the database driven production and incremental data updating, in order to provide new methods for topographic mapping pro duction and update under informationization surveying. The technical application in the article have been successfully carried out in the national 1 ： 50 000 topographic mapping production project, and widely ap plied in the provincial bureaus of surveying and mapping.
