EIA-9900268 Samet，Hanan University of马里兰州，College Park数字政府：NSF-CNPq协作研究-空间数据表和浏览器开发中的问题该提案将开发算法和系统，以支持空间数据的索引，连接和查询，输出为表格数据（电子表格）而不是渲染地图。 待探索的技术包括矢量和栅格数据的存储和检索、多分辨率层的表示以及查询优化。 该项目在巴西的合作者是Jano Moreira de Souza教授和Claudio埃斯佩兰卡。联邦伙伴关系将通过联邦地理数据委员会进行协调;美国地质调查局将是重点机构。
英文摘要
EIA-9900268Samet, HananUniversity of Maryland, College ParkDigital Government: NSF-CNPq Collaborative Research - Issues in the Development of Spatial Spreadsheets and BrowsersThis proposal will develop algorithms and systems to support indexing, joining and querying of spatial data, with output as tabular data (spreadsheets) rather than rendered maps. Technologies to be explored include storage and retrieval of vector and raster data, presentation at multiple resolution layers, and querying optimization. Collaborators in Brazil for this project are Professors Jano Moreira de Souza and Claudio Esperanca.Federal partnership will be coordinated through the Federal Geographic Data Committee; the U.S. Geological Survey will be the focus agency.
