BIM模型和GIS数据数字化服务系统

系统是基于大型国有平台企业或城市运营商土地规划、项目管理及运营的需求开发完成的，可提供建筑工程全生命周期，全流程，全要素数字化服务。

　　平台可以实现从单个建筑项目到企业总体项目管控的层级管理，并且可与政府主管单位平台进行对接，满足城市管理、园区管理的要求。其中GIS技术作为系统的重要组成版块，将地理图形数据和建筑工程合成高精度三维实景模型，通过空间关系模拟、大数据存储分析、对整个片区进行实时、动态、可视化的全方位管理，为建设CIM系统提供最坚实的数据基础。

　　本系统基于超图GIS实现了BIM模型和GIS数据在平面坐标系和地理坐标系之间的转换，实现在地球曲率影响下的BIM模型和GIS数据精确匹配，避免渲染时的裂缝和漏洞等问题，在GIS移动端平台上将数字化的BIM投放到任何场景中。将设计方案与实际施工现场进行比对，可以及时发现问题并进行修正。最终实现BIM管理平台、智慧工地、GIS平台三方联动，贯穿项目的全过程生命周期，提高了工程管理的信息化水平。
