Design and implementation of land resource management WebGIS based on resource-oriented architecture(ROA)(基于面向资源架构的土地资源管理WebGIS的设计与实现) by MAOFeng(毛峰), LIUTing(刘婷), BAOWei-zheng(包卫正), LIURen-yi(刘仁义), LIUNan(刘南), ZHANGFeng(张丰)

“…结合具有表述性状态转移(REST)风格的Web Service与开放地理信息联盟(OGC)开放标准规范，提出一种面向资源的WebGIS架构及其设计方法.在该架构中，为实现信息共享和功能互操作，采用OGC规范作为服务接口标准，服务采用REST风格加以实现，并以资源的形式对外公开.所有的资源共享统一的界面，在服务器与客户端之间进行状态的传输.为验证该架构，构建了一个基于网络的土地资源管理原型系统，该系统可在多元异构的网络环境下进行信息发布和信息获取，并实现查询、变更等土地利用管理常用功能.…”

Research on the analysis and statistic of geographical conditions based on the strategy of "Grid Index + MapReduce"(“格网索引+ MapReduce”策略下的地理国情统计分析研究)... by LINYaping(林雅萍), DUZhenhong(杜震洪), ZHANGFeng(张丰), LIURenyi(刘仁义)

“…地理国情统计分析是深度研究地理国情普查数据的首要前提.针对现有单机集中式数据存储与处理方式存在耗时长、效率低甚至不支持的问题，设计了“格网索引+MapReduce”策略，基于规则格网设计普查数据文件的分块组织与分布式存储方式，研制了格网索引与空间分析相结合的双层过滤机制，构建基于MapReduce的地理国情并行统计算法.最后，与无索引MapReduce、ArcGIS平台进行性能对比测试，结果表明：“格网索引+ MapReduce”方法的统计效率远高于ArcGIS平台，对无索引MapReduce方法亦有明显的效率优势，研究拟为地理国情普查数据的高性能、多类型、大批量统计分析提供优选方案.…”
