基于supermap 3d-webgl技术的商务楼宇信息监测系统大数据 三维

     为进一步促进楼宇信息联动，优化监管机制和服务流程，强化协同监管，在某区政府主导的楼宇信息监测项目中，对此设计研发并上线了某区商务楼宇信息检测系统。通过系统的建设，方便政府部门宏观分析楼宇投入产出经济效益、产业集聚生态效应、科技创新活力常指标，为政府调整区域产业结构，培育特色专业楼宇提供支撑，加强市场化、专业化企业服务能力建设，吸引有竞争力的民营企业总部和跨国公司地区总部，引导符合城市战略定位的总部企业向价值链、产业链、创新链高端发展，实现支持与城市战略定位相匹配的总部经济发展，推动楼宇经济的更新升级。

　　本系统利用超图集团研发的SuperMapGIS平台软件，有效整合各类楼宇信息、促进商务楼宇和集中办公区企业发展、优化营商环境;依托大数据、物联网、三维可视化展示、人工智能等先进技术，围绕楼宇，开展精细化监管，完成对楼宇、物业和企业的全景画像，通过大屏、PC端等渠道，从全局、区域、单体楼宇等多个场景，动态、直观、多维度的展示监测信息。

　　基于空间地理信息、3D渲染和人工智能等技术，实现楼宇信息的可视化展示和智能化交互。以某区二维和三维地图为基础，叠加展示三维楼宇模型。增加对市场主体的监管和服务的方式和手段，规范楼宇企业的经营行为，实现楼宇经济的健康有序发展，不断推进经济发展向着科学化方向前进。

　　通过GIS平台，建设三维交互展示系统，完成楼宇三维模型创建、楼宇模型展示、地域情况地图分析展示、部件情况地图分析分析展示、产业情况地图分析展示、楼宇指标情况地图分析展示等功能，实现二维图表与三维场景结合，适应各种各样的可视化场景，并提供炫丽的图形界面效果，使信息展示更具体、决策更高效。部分源码，开源如下：
