互联网+地表覆盖验证及应用
|
Abstract:
为有效地组织大范围地表覆盖数据验证，需要发动和组织来自不同地域、不同机构的专家，但往往缺少网络化环境下的协同验证方法和工具。针对这一问题，将互联网+、服务计算技术等与地表覆盖验证业务相融合，提出了互联网+地表覆盖验证服务模型，构建了面向互联网+的地表覆盖验证业务流程和方法，研制了基于景观形状指数（landscape shape index，LSI）抽样算法的在线验证系统GLCVal（global land cover validation），为大范围、高分辨率地表覆盖数据验证提供了新思路、新方法。利用所提出的方法与系统，与GEO（Group of Earth Observation）、UN-GGIM（the United Nations Initiative on Global Geospatial Information Management）等组织合作开展了GlobeLand30的全球验证，有效支持了跨区域专家的主动参与、多角色协同，促进了验证资源联通和共享，提高了验证效率
