纸质地图与地理信息一体化生产技术研究

纸质地图制作和地理信息生产构成数字地图制图中两大相对独立的研究领域,在分析两者异同的基础上,设计了纸质地图与地理信息一体化生产流程,阐述了实现一体化生产必须解决一体化数据结构设计、多源数据综合利用、地图符号化机制建立、基于地理属性管理的地图编辑、地图数据质量检查、一体化地图输出等关键技术。纸质地图与地理信息一体化生产标志着数字地图制图发展进入了新阶段。

The Integrative Technology of the Paper Map Production and the Geographic Information Capturing

The paper map production and geographic information capturing are two independent aspects of digital mapping.The two workflows of them are not same.In this paper,we research the integrative technology of producing the paper map and geographic information,in order to resolve the problem of how to make two products in one process.Firstly,we analyze the different requirement between the paper map production and geographic information capturing,and point out that the focus of paper map production is graphics or symbol and the focus of geographic information capturing is geographic feature code,and design the integrative workflows.Then,we must resolve several problems in the integrative workflow: the integrative structure of vector data,multi-source data using,map symbolization,map editing,data checking,the integrative printing.As a result,integration of paper map production and geographic information capturing is a new technology of digital mapping.Digital mapping system,which adopts this technology,can change single-production mode into multi-production mode.The digital mapping technology will be advanced to a higher level.
