无控区域1∶5万卫星遥感测图技术方法浅析

无控区域测图是测绘的一个重要范畴,是实现对大陆周边岛屿、礁石的基础测绘、国家空间地理信息建设的重要保障。在无控区域测图过程中,方法的正确选取、技术的合理运用是提高无控区域测图科学性、可行性的关键。本文在分析“无控区域卫星遥感测图”技术理论的基础上,结合现阶段实施的相关项目和实验,阐述了无控区域一种控制点获取方法以及潮汐改正的应用,总结了“无控区域卫星遥感测图”相关技术方案的应用条件及不足之处,同时也展望了未来无控区域测图技术的发展方向。

Technical Analysis of Small Scale Satellite Remote Sensing Cartography in Areas without Control Points

The mapping of areas without control points is an important category of surveying and mapping,and it is an important guarantee for the realization of basic surveying and mapping of islands and reefs around the mainland and the construction of national spatial geographic information.In the process of the mapping of areas without control points,the correct selection of methods and the rational use of technology are the keys to improving the scientific and feasibility of the mapping of areas without control points.Based on the analysis of the technical theory and the related projects and experiments implemented at this stage,this paper describes a method for obtaining control points in areas without control points and the application of tide correction.The application conditions and deficiencies of the technical solutions,and the future development direction of uncontrolled area mapping technology is also prospected.
