遥感大数据实时渲染与交互可视化研究

数据可视化是遥感应用的重要服务出口。针对静态的预生成瓦片地图难以满足数据查看、地图配置、空间分析等专业应用问题,本文提出了一套面向遥感大数据的实时渲染与交互可视化的解决方案。在渲染节点构建影像的渲染瓦片结构,以提高数据的读取速度;在可视化服务上,提出“数据-计算”相一致的负载均衡策略,优化地图的渲染效率;在可视化服务方面,设计交互的地图服务接口。与传统技术的对比分析表明,该解决方案不但实现了遥感大数据的实时渲染与交互可视化,并且达到了与预生成瓦片地图服务相当的服务性能。基于这一解决方案,研发了遥感大数据的动态可视化原型,并在影像数据实时查看、可视化计算、可视化分析等方面开展了示范应用。     

A model of a heterogeneous neighborhood

Tel Aviv is a highly ethnic city in which ethnicity is deeply embedded in people’s perceptions of their social milieus. Shapira, as one of the most heterogeneous neighborhoods in Tel Aviv, supplies a unique demonstration of the inadequacy of the Chicago model, which assumes the emergence of homogeneous neighborhoods. The study shows that ethnicity is exercised as a major force in determining social life in Shapira. Interactive segregation indices reveal that residents of Shapira tend to prefer intra-ethnic social networks although two-thirds of them maintain inter-ethnic networks as well. Despite this, residential and activity spaces are highly heterogeneous. Residential spaces are heterogeneous on all scales from residents’ immediate surroundings to the block and the neighborhood as a whole. In most buildings one may find neighbors from two or three different ethnic groups with only non-Jewish residents excluded from publicly owned buildings. Most residents perform large part of their everyday life outside the neighborhoods in ethnically heterogeneous surroundings, but nonetheless in choosing their more meaningful partners for social networks they choose them from their ethnic groups. The fact that residents tend to perform a large part of their activities out of their neighborhood, and to live in heterogeneous surroundings in social categories that are perceived by them salient to their daily life, does not undermine the relevance of the neighborhood as a socially constituted entity in the urban field. People organize and act in order to improve life conditions in the neighborhood, they feel sense of attachment to the neighborhood and they develop some local social networks in the neighborhood.

利用ATSR/ERS-1资料研究复杂下垫面比辐射率的变化

一定精度地表温度的取得不仅依赖于较好的大气订正,而且还取决于比辐射率随波谱及角度变化的知识。利用AVHRR植被指数资料,参数化了星下点的比辐射率值,得到了对于包括沙漠、绿州、戈壁等不同类型的复杂下垫面上的星下点比辐射率的值。结合ATSR的双角度技术,计算了复杂地形条件下前向地表比辐射率,给出了一种利用ATSR资料获得有关地表比辐射率信息的新方法。
