III: Gulf RAPID: Multi-temporal analysis and correlation of Gulf Oil Spill Related Geospatial Data on TerraFly Platform

佛罗里达国际大学正在加强其TerraFly技术，增加了对空间和时间科学测量聚合的可视化支持，特别适用于受墨西哥湾漏油影响的沿海和近海地区。FIU正在收集数据、开发算法和制作原型，并支持特殊用途功能的规范、数据分析、可视化和知识发现。该项目涉及数据的可获得性和可获得性方面的紧迫问题，并涉及海湾石油泄漏对沿海社区的经济影响的快速反应研究。需要有效地支持新形式的分析查询。例如，一家保险公司可能需要回答以下复杂的查询：“对于任何给定的财产，对于区域，通过将佛罗里达州狭长地带的价值变化与其他地方类似分区的财产的百分比变化进行关联，根据类似的土地使用(分区)、财产大小、到水的距离以及近海和沿海石油污染进行调整，找出漏油对一个或多个财产的价值下降的影响。”正在开发的算法和原型系统能够对地理空间数据进行时间查询、交叉参考、可视化和分析，包括时间序列多时相航空图像、多时相测量和经济数据以及大量现有的静态地理空间数据库。这项研究可以分析图像和矢量的差异，查询每个地点的差异，并提出一系列与墨西哥湾漏油事件对沿海社区的经济影响有关的问题。这一快速项目的结果将使研究人员、利益攸关方和普通公众能够通过灵活的图形界面访问、查询和分析相关数据库。金融情报室和校外研究人员将能够获得多时相高分辨率图像和矢量数据。系统到系统的XML访问将使所有学术研究人员能够使用该项目的GeoQuery系统。可通过项目网站(http://terrafly.fiu.edu/r.htm).)访问用户可定义和预定义的项目查询数据和图形界面

Florida International University is augmenting its TerraFly technology by adding support of visualization of scientific measurement aggregation through space and time with a specific applicability to the coastal and near-coastal areas affected by the Gulf Oil Spill. FIU is assembling data, developing and prototyping algorithms and to support specification of special-purpose functions, data analysis, visualization, and knowledge discovery.This project deals with a severe urgency with regard to availability of, and access to, data and involves quick-response research on the economic impact of the Gulf Oil Spill on coastal communities. New forms of analytical queries needs to be efficiently supported. For example, an insurance company may need to have the following complex query answered: "For any given property, in aggregate for areas, find the value decrease impact that the oil spill had on the property or properties; by correlation of value changes in Florida Panhandle to percentage change of similarly zoned properties elsewhere, adjusted for similar land use (zoning), property size, distance to Water, and near-coastal and coastal oil contamination". The algorithms and prototype system being developed enable the temporal querying, cross-referencing, visualization, and analysis of geospatial data, including time series multi-temporal aerial imagery, multi-temporal measurement and economic data, and vast existing static geospatial databases. This research enables analysis of differences in imagery and vectors, allows querying differences per location, and the posing of a range of questions pertaining to the economic impact of the Gulf Oil Spill on coastal communities. Results of this RAPID project will allow researchers, stakeholders, and the general public to access, query and analyze relevant databases via flexible graphic interfaces. FIU and extramural researchers will have access to multi-temporal high-resolution imagery and vector data. A system-to-system XML access will enable all academic researchers to use the project's GeoQuery system. The project's data and graphic interface to queries, both user-definable and pre-defined, will be accessible via the project web site (http://terrafly.fiu.edu/r.htm).
