NGA and DigitalGlobe open source toolkit to harness the power of collaborative mapping NGA和数字地球公司开源工具以加强协作式地图（众源地图）的作用 Don Kerr, Chief of Media 海天山树（译） 2015.06.22 SPRINGFIELD, Virginia — The National Geospatial-Intelligence Agency and DigitalGlobe have partnered to release an open source software toolkit designed to harness the power of crowdsourced mapping for Geospatial Big Data Analytics. The open source project Hootenanny provides a scalable processing engine and interactive editing interface to enable rapid conflation of map features generated from satellite imagery, UAVs, and mobile devices. NGA和数字地球公司已经合作发布了一款开源软件工具，用来加强众源地图在地理大数据分析中的作用。开源项目Hootenanny提供了一个可伸缩的处理引擎和交互编辑界面，以能够快速整合由卫星影像、无人机数据和移动设备数据产生的地图要素。 In less than a decade crowdsourced mapping communities like OpenStreetMap have attracted over 2.5 million volunteers who have digitized more than 130 million buildings and 1.3 million miles of roads. Countless other organizations and individuals are using satellite imagery and other methods to capture the geometry and metadata of roads, buildings, and points of interest. To create high quality maps and enable analytic functions like routing, suitability analysis, or predictive modeling it is important to unify multiple sources to create the best available database. 不到十年时间，众源地图团体如OSM已经吸引了超过250万志愿者，这些志愿者提供了超过1.3亿建筑物和130万英里道路的数字化信息。难以数计的其他组织和个人正在使用卫星影像和其他方法去获取道路、建筑物和兴趣点的几何结构和元数据。为了构建高精度的地图，并能够进行像路线、实用性分析或者预测模型等分析功能，整合多源数据构建最好的可用数据库是十分重要的。 “The commercialization of GEOINT is leading to exponential growth of publicly available geospatial information,” said Chris Rasmussen, NGA’s public software development lead. “Hootenanny as an open source project will enable new levels of data sharing across the community that will increase our nation’s ability to quickly respond to emerging threats. This is a pro-active move that steers into the collaborative mapping environment to derive more value from unclassified sources.” NGA的公众软件发展部领导Chris Rasmussen说：GEOINT的商业化正使得公众可获取的地
