城市大比例尺地形图动态修补测信息化管理平台建设

大比例尺地形图的动态修补测能够及时反映地理要素变化,是确保地理信息现势性和地理空问框架服务能力的一项重要工作.本文分析了城市区域地形图动态修补测管理工作的流程,指出了传统管理方法存在的问题,提出了多渠道变化发现与及时发布、任务线上流转与监督管理、基于要素的数据入库与增量更新等的信息化管理方法,并基于此建设了城市大比例尺...

Construction of informatization management platform for large-scale urban terrain dynamic patch surveying

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.
