摘要
当前GIS在以服务为主要特征的空间信息共享时代承担着重要的角色。在地震行业系统大数据的时代背景下,电子地图已经展现出极大的应用潜力,但是由于行业数据涉密性,导致GNSS、区域精密水准等观测数据不能与电子地图充分结合展现其优势。针对该实际问题,将主流网络电子地图服务免费对外开放的应用程序接口API和部分基础地图数据迁移到本地,并通过坐标系转换算法进行地理位置纠偏,实现基于行业网的电子地图本地化应用。进一步基于主流GIS软件开发地图切片程序,研究有效的数据组织策略,建立地图瓦片数据库,存储地图数据,为行业网电子地图应用提供地图数据服务,有效解决了地震行业基于电子地图的涉密数据可视化问题。
Currently,GIS plays an important role in the era of spatial information sharing characterized by service.Under these circumstances of big data age in the earthquake industry system,the electronic map has shown its tremendous potential,but the information of GNSS and the data of the regional level precision observation cannot be fully combined with the electronic map because of the secret data of the earthquake industry system.Aiming at the practical problems,we move the open API of the electronic map and some basic map data to the local and rectify the geographical position by the coordinate transformation algorithm,which to be the local application of electronic map based on earthquake industry network.Based on mainstream GIS software we further develop the map slicer program,studying the effective data organization strategy,establishing database of map tiles,storing map data,which provides map data service for the industry network electronic map application and effectively solve the visualization of secret data based on electronic map in earthquake industry.
