摘要
地球剖分网格作为传统地理坐标参考的有效补充,具有形状近似、空间无缝不重叠、尺度连续、全球统一的刚性定位等优势,与REST(Representational State Transfer)Web服务的结合可完成空间区域位置标识下的影像数据互操作。基于此,本研究基于地球剖分网格探索遥感影像数据REST资源化方法,定义了面向资源架构(Resource-Oriented Architecture,ROA)的URI标识模型,从面向资源的角度设计互操作协议函数,采用地球剖分网格单元的地址编码代替传统地理坐标以刚性定位资源化影像。最后,以北斗网格作为参考网格,开发分析就绪(Analysis-Ready)资源化影像服务原型系统,并开展互操作案例研究,验证了影像数据资源刚性定位互操作模型用于影像资源共享互操作的可行性和有效性。
The globe subdivision grid,as an effective supplement to traditional geographic coordinate references,has the advantages of shape approximation,seamless non-overlapping space,continuous scale,and global uniformity in rigid positioning.When combined with REST(Representational State Transfer)Web services,it can achieve interoperation of image data under spatial region position labeling.Based on this,this study explores the REST resource-oriented method for remote sensing image data based on globe subdivision grid,defines a Resource Oriented Architecture(ROA)URI identification model,designs interoperation protocol functions from a resource-oriented perspective,and uses address encoding of globe subdivision grid units instead of traditional geographic coordinates to rigidly locate resource-oriented images.Finally,using the Beidou grid as a reference grid,an Analysis Ready resource-oriented image service prototype system was developed,and an interoperation case study was conducted to verify the feasibility and effectiveness of the rigid positioning interoperation model for image data resources for image resource sharing and interoperation.
