摘要
在大数据时代背景下,如何合理利用已有数据资料开展研究及科普工作是十分重要的课题。研究借助云平台公开数据、无人机数据、遥感数据、GIS数据等形成了多尺度、多维度、多视角的周口店虚拟仿真交流平台界面。采用基于HTML5与网络图形库WebGL的开源框架Three.js,将网站中内嵌3D交互操作,应用Java搭建POI和标注注释与图片信息,从而实现多人在线、共享、定位、数据上传、多人聊天、导航、三维仿真等平台功能。通过php提供的API接口及MySQL将庞大的用户数据、地质云数据以及地质调查局数据存入数据库,不仅满足了地质专业人员的教学需求,同时可为大众普及基本地质知识,并能够为无法亲临周口店的人群提供虚拟仿真三维平台,极大地实现了大数据时代背景下的信息知识的传递与共享,具有十分重要的意义。
In the era of big data,how to carry out research and science popularization by rationally utilizing existing data is an important topic.In this study,a multi-scale,multi-dimensional,multi-perspective Zhoukoudian virtual communication platform interface was established with the help of cloud platform open data,UAV data,remote sensing data,GIS data,etc.Interactive operation was performed on the website embed 3D using the open source framework Three.js,which is based on HTML5 and Web Graphic Library(WebGL).Meanwhile,POI was built,and annotation and pictorial information were marked by applying Java,thus implementing platform functions including multiuser online,sharing,positioning,data uploading,multiuser chat,navigation,3D simulation,etc.Via the API interface provided by php and MySQL,the huge user data,geocloud data and geological survey data were stored in the database,which not only meets the teaching needs of geologists,but also helps popularize basic geological knowledge to the public.Furthermore,it can offer a virtual 3D platform for those who are unable to personally visit Zhoukoudian,thus maximizing the transfer and sharing of information knowledge in the big data era,which is of great significance.
