陆海融合制图技术研究

Research on Land-Sea Integration Mapping Technology

为实现陆海地理信息数据融合、测绘成果一体化显示,本文对陆海融合制图技术展开研究,首先对比分析了传统地形图与海图在数学要素、地理要素、辅助要素、信息获取技术与数据精度方面存在的差异;在此基础上,论述了数学基础一致性处理、陆海融合地理信息要素编码体系与符号体系设计等关键技术,并提出了实现思路及一种要素编码体系设计方案,最后对某近海区域进行了陆海融合制图示范性研究,为陆海融合制图提供了思路与方法。

To realize the landsea geographic information data fusion and integrated display,this paper studies the land-sea fusion mapping technology.The differences of mathematical elements,geographical elements,auxiliary elements,information acquisition technology and data accuracy between traditional topographic map and nautical chart are compared and analyzed.On this basis,the paper discusses the key technologies of consistency processing and conversion of map data mathematical base,coding system and symbol system design of land-sea integration geographic information elements.A land-sea fusion mapping experiment is carried out,which provides ideas and methods for land-sea fusion mapping.
