Abstract: The large-scale terrain dynamic patch surveying is an effective way to obtain the latest geographic information. It is an important work to ensure the current situation of the topographic map and the service capability of the geospatial framework.This paper analyzes the management process of dynamic patch surveying of topographic maps in urban areas, points out the problems of traditional management method. And proposes multi-channel change discovery and timely releases, online task transfer and supervision management, element-based data storage and increment update and other informatization construction methods. Based on this, an informatization management platform for dynamic patch surveying of large-scale topographic maps is built. The construction results of this paper have been applied to the Shenzhen 1:1000 topographic map object-oriented dynamic patch surveying work, which has fully verified its effectiveness.

Key words: topographic map, patch surveying, dynamic updating, change discovery, informatization management
