基于Baidu Map/天地图建筑物矢量化方法研究

Research on Building Vector Method Based on Baidu Map and Map World

针对建筑物特点和抗震易损性评估要求,研究了基于ArcGIS平台的天地图建筑物数据加载于Baidu Map的矢量化方法,探讨了Baidu Map与天地图的坐标转换,提出了最佳公共点快速搜索算法,实现了数据批量采集与精确匹配。结合宿迁市宿城区建筑物矢量化实验案例,验证了其有效性和便捷性。

The vector method of loading building data from Map World into Baidu Map based on ArcGIS is proposed according to the requirements of building characteristics and seismic vulnerability assessment.The coordinate transformation between Baidu Map and Map World is studied,a fast search algorithm for optimal common points is proposed,and mass data collection,accurate matching are realized.With the building information of Sucheng District of Suqian City,the effectiveness and convenience of which are verified.
