针对目前遥感影像中云信息描述简单、云的空间分布信息不足而限制影像局部云信息检索的现状,提出了基于GeoSOT的影像云索引模型。该模型根据空间信息建立GeoSOT网格与遥感影像的对应,通过判断每个GeoSOT剖分面片对应的影像数据块是否有云,并记录剖分面片编码和判断结果,实现对遥感影像中局部云信息建立索引;在检索影像中局域云信息时,根据剖分面片编码查找云信息标识即可。同时,探讨了不同等级影像数据产品采用精确逻辑剖分和冗余逻辑剖分构建影像云索引的方法,设计了影像云索引的数据结构,分析了影像数据建立云索引的存储代价。通过仿真实验表明,对遥感影像构建基于GeoSOT剖分编码的云索引代价小,其存储量约为原数据的0.01%,提高了影像中局部云信息查询效率,为计算机自动选取高质量的影像提供了一个有效的技术途径。  相似文献

随着空间技术和对地观测技术的飞速发展,海量遥感影像索引成为目前国内外学术界和应用部门面临的一大难题,地球剖分系统的产生为这一难题的解决开辟了新的途径。本文首先研究了遥感分景数据的特征和EMD全球剖分的特征,然后针对现有遥感影像数据索引方法的不足,提出了基于EMD剖分系统的三种索引模型:基于影像—面片映射关系的索引模型、基于EMD数据模型的索引和剖分数据标识索引模型,从三个不同的方面探讨了解决索引问题的方法和思路。并给出了利用遥感分景数据的剖分索引模型对线状对象和面状对象进行索引应用的实例。遥感分景数据的剖分索引模型的建立为遥感影像数据的高效存储和索引提供了一种有益的新思路。  相似文献

遥感影像剖分金字塔研究   总被引:1,自引:0,他引:1  
分析了全球剖分格网与影像金字塔的优点与不足,结合两者的优势提出了剖分影像金字塔模型及建塔策略,利用全球剖分格网面片编码的唯一性和Hilbert曲线空间连续性对影像块进行索引与组织。针对基于影像块组织的特点,提出了剖分影像金字塔局部更新的方案。实验结果表明,剖分影像金字塔不仅具有传统影像金字塔在快速浏览上的优势,并且由于其编码和索引的优势,使得在局部影像提取和更新方面效率更高,有一定的使用价值。  相似文献

多级地理空间网格框架及其关键技术初探   总被引:1,自引:0,他引:1  
为了有效管理、组织和利用海量空间数据,解决存储架构与现有空间数据结构不一致的矛盾,在融合国内外各种球面剖分模型优点基础上,设计了一种多级地理空间网格框架。该网格框架以地图分幅划分方式为基础,利用经纬度间隔对全球进行层次性剖分,形成遥感数据、测绘数据及其他空间数据的统一组织框架。通过对网格单元的地址与属性编码,实现空间数据的直接存储和索引,从而完成对空间信息的无缝拼接与多尺度管理。最后阐述了实现地理空间网格框架的关键技术,包括空时一体化技术、计算集群存储技术和空间索引技术等。  相似文献

现有模型对影像数据中的地理对象进行多尺度表达很困难,鉴于全球剖分模型在对地理对象表达时所具备的全球唯一性、层次性、多尺度性、编码具有地学含义等特点,提出了面向地理对象多尺度表达的剖分编码方法,目的是对地理对象赋予统一的剖分编码,使编码具有地学含义和多尺度特性.实验证明,面向地理对象多尺度表达的剖分编码方法可以满足地理对象多尺度剖分化表达的需要,为新一代GIS解决地理信息"尺度鸿沟"问题,向用户提供"连续"、"自适应"的表达尺度奠定了基础.  相似文献

很多遥感影像应用的情况下,用户需要及时获取最新的影像,其中优先级最高的应是影像的变化区域;对于那些没有变化或变化不重要的区域,则没有必要立刻传输最新时相的影像.根据上述思路,基于地图分幅拓展的全球剖分模型,利用剖分面片管理多时相的影像数据,并将其中的变化区域表达为最小外包面片(MBC)的集合.影像更新时只需传输变化区域MBC集合中的影像面片,从而减少影像更新时的数据传输负担.该文实现了影像分发平台,对MBC方法进行了验证,试验表明利用MBC进行影像变化区域表达能够满足降低数据传输负担的要求.  相似文献

全球离散格网系统是递归剖分整个地球空间形成的多分辨率离散地球参考模型,有助于建立以空间位置为主键的多源数据关联融合新模式。正二十面体的三角面不利于建立格网单元行列索引,且生成的球面格网单元存在较大形状差异,对此,该文采用面数更多、结构更优的菱形三十面体构建六边形全球离散格网系统。首先,在单个菱形面上建立离散斜坐标系描述多种孔径六边形剖分产生的多分辨率格网;其次,根据菱形三十面体的几何属性确定跨面单元归属,据此拼接各面上的多分辨率单元,构成封闭三十面体上的格网系统;最后,通过Snyder等积多面体投影将封闭菱形三十面体上的格网系统映射至球面。实验结果表明,相比二十面体的同类成果,菱形三十面体六边形全球离散格网系统的几何属性和应用潜力更好,有助于建立地球空间信息数据的高精度承载模型。  相似文献

为了从格网剖分结构上解决分块LOD(Level Of Details)模型中复杂的块内、块间裂缝问题,避免目前裂缝消除方法的缺陷,该文提出一种基于多分辨率半边结构的分块LOD模型无缝表达方法。首先,引入多分辨率组合映射理论,给出基于多分辨率半边的菱形块多尺度表达的基本方法,包括菱形块剖分方法和编码方法;在此基础上,提出块内、块间格网无缝表达机制,设计并实现了基于菱形块的全球地形动态LOD管理机制;最后,应用C语言和DirectX工具,开发了相应的可视化实验系统。实验表明:该方法从格网剖分结构上解决了全球地形分块LOD模型中的块内、块间裂缝问题;与传统方法相比,其不需要限制相邻格网的剖分层差,简化效率更高,且无地形失真。  相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world's largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.  相似文献

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.  相似文献
