摘要
针对大区域遥感影像处理中数据组织和应用方面的技术难题,该文采用GeoSOT剖分网格体系理论的数据组织方法,建立影像型地理空间数据逻辑剖分与编码,同时提出了基于网格模板的影像按需快速拼接技术,依托空间剖分网格高精度的空间关系,直接从遥感影像中抽取所需的剖分面片进行几何拼图,实现了大区域遥感影像数据的快速组织和拼接,提高了数据浏览等应用的效率。在数据共享上,考虑到异构网络环境下数据实时共享的应用要求,设计了有限带宽条件下的智能传输策略。依托空间剖分网格天然的"多尺度、小面片"的特点,设计灵活的传输策略,在有限带宽网络条件下,以面片为单位,实现用户关心区域的目标信息的快速传输分发,改善数据传输效率和用户体验。
Aiming at the problem of data processing technology organization regional remote sensing images and the application of data organization method using GeoSOT subdivision grid system theory,establish the image based spatial data logic dividing and encoding,and proposed based on grid template image on-demand fast mosaic technology,relying on the space division of space grid with high precision the relationship,directly from the remote sensing image extraction required for subdivision surfaces in geometric puzzles,to achieve a rapid data remote sensing image regions and splicing,improve the efficiency of data browsing and other applications.in data sharing,considering the application of heterogeneous network environment,real-time data sharing requirements,design the function of transmission strategy under the condition of limited bandwidth,based on spatial mesh natural"multi-scale and facet"characteristic,transmission strategy of flexible design,in limited bandwidth network conditions,to patch as a unit fast,transmit the information users concerned about regional distribution,improve the efficiency of data transmission and user experience.
