摘　　要：目前,互联网中的测绘地理信息丰富且分散,导致用户难以快速精确的获取相关信息。同时,通用搜索引擎及某些商业网站的竞价排名又进一步加大了测绘地理信息获取难度。针对此情况,文章利用NCrawler、Html Agility Pack、Lucene. net等开源工具,构建了测绘地理信息聚合系统,实现了对互联网中测绘地理信息的采集、查询与展示功能。Now,there are more and more abundant and scattered information about surveying,mapping and geographic information in the network.It makes it difficult for users to get the relevant information quickly and accurately.At the same time,the bidding rankings of general search engines and some commercial websites have further increased the difficulty of acquiring the surveying,mapping and geo-information.Therefore,a surveying,mapping and geographic information aggregate system was built based on the open source software of NCrawler,HtmlAgilityPack and Lucene.net etc.The system realizes the function of crawling,querying and displaying the surveying,mapping and geographic information.
