摘要全球土地覆盖和变化信息的必要性和重要性已得到公认。虽然已经收集了大量的此类信息，但由于缺乏必要的信息服务来支持这些信息的便捷获取、分析和验证，因此难以通过精心设计的工作流程来查找、评价、选择和重新使用这些信息。为促进全球土地覆盖信息服务的发展，提出了全球土地覆盖信息合作服务（CoGland）的概念框架，并讨论了其实施策略。该框架支持世界各地相互连接和共享的土地覆盖和变化网络服务，以满足资源共享、社区服务和跨部门协作的需要。CoGland可以使最近的几项国际倡议（如未来地球）和许多社会福利领域受益。该论文进一步建议在联合国全球地理空间信息管理专家委员会、国际摄影测量和遥感学会等多个关键组织的支持下，在地球观测组织的框架内开发CoGland。和国际数字地球学会。希望本文可以作为进一步讨论CoGland发展的起点。
ABSTRACT The need and critical importance of global land cover and change information has been well recognized. Although rich collection of such information has been made available, the lack of necessary information services to support its easy access, analysis and validation makes it difficult to find, evaluate, select and reuse them through well-designed workflows. Aiming at promoting the development of the needed global land cover information services, this paper presents a conceptual framework for developing a Collaborative Global Land Cover Information Service (CoGland), followed by discussions on its implementation strategies. The framework supports connected and shared land cover and change web services around the world to address resource sharing, community service and cross-board collaboration needs. CoGland can benefit several recent international initiatives such as Future Earth, and many societal benefit areas. The paper further proposes that CoGland be developed within the framework of the Group on Earth Observations with the support of a number of key organizations such as the United Nations Expert Committee on Global Geospatial Information Management, the International Society for Photogrammetry and Remote Sensing, and International Society of Digital Earth. It is hoped that this paper can serve as a starting point for further discussions on CoGland developments.
