摘要
从智慧城市、大数据时代的要求与地图的独特分析功能出发,探讨了大数据时代对地理空间信息及其可视化的要求和技术。对智慧城市建设时期的地理空间数据而言,不仅要求内容更全面更详细、表达更直观更仿真、建模结构化或实体化,而且要求向室内空间与室外空间融合、地上空间与地下空间融合、过去数据与现在数据融合、现在数据与未来数据融合的方向发展。
Based on the needs for the smart city and big data era as well as the unique analysis function of maps, the requirements and technical essentials of geospatial information and visualization for the big data era are discussed in detailed. In the period of the smart city construction, it is necessary for the spatial data not only to posses more comprehensive and detailed content, more direct expression and modeling and materialization, but also capable to develop towards the direction of data fusion, which includes the fusion between indoor spatial data and that of outdoor, the intergration between data underground and that of above the surface, the combination between previous data and that of the current as well as future.
