摘要 以移动GIS在土地利用变更调查中的应用为研究对象,研究了与栅格影像数据存储、矢量空间数据组织与管理相关的关键技术。基于数据库进行栅格瓦片存储,提高了底图栅格数据传输的便捷性和显示性能,同时改进了空间数据模型与空间索引结构,提高了移动GIS对土地变更数据的管理性能。 In this paper, taking the application of mobile GIS in land use change survey as the research object, we researched on key technologies of raster image data storage, organization and management of spatial data. Tile grid storage based on database improves the transmission convenience and display performance of base map, while raising the spatial data models and spatial indexing structure, and improving management performance of mobile GIS for land change data.
