基于高分卫星影像的自然资源专题图制作

Natural Resources Thematic Map Making Based on HighResolution Satellite Image

自然资源信息的数字化、可视化、可共享是促进自然资源进一步实现合理开发、适度利用的有效手段。采用地理信息系统(GIS)、遥感(RS)、全球定位系统(GPS)相结合的方式,基于国产高分系列卫星影像,统一数据处理、外业调查、解译标志库建立、内业判读、图斑处理以及图面整饰等步骤和方法,形成基于3S技术的完备的自然资源专题图制作流程,提供可视化、可共享的数字化成果,满足自然资源合理开发利用和保护管理的现代化需求。

Digitalization,visualization and sharing of natural resources information are effective means to promote the rational development and proper utilization of natural resources.By using the combination of geographic information system(GIS),remote sensing(RS)and global positioning system(GPS),based on the domestic high-resolution series of satellite images,this paper unif ies the steps and methods of data processing,f ield investigation,establishment of interpretation mark database,internal interpretation,map spot processing and map surface decoration,forms a complete production process of natural resources thematic map based on 3S technolog y,provides visual and shareable digital results,and meets the modern needs of rational development,utilization,protection and management of natural resources.
