For the spatial overlay analysis of vector data on the condition of mass data and confined memory, the paper proposes spark-based iterative spatial overlay analysis algorithm. The algorithm builds multi-level grid index structure combining the first-level grid with quartering ,designs memory space data structure and implements spatial overlay analysis of mass vector data based on Spark distributed computation platform. The experimental result indicates that the algorithm, compared with spatial overlay analysis algorithm in ArcGIS and spatial database PostGIS and Spark-based quad tree index algorithm, enhances the efficiency of spatial overlay analysis obviously. Therefore, it is more suitable for spatial overlay analysis of vector data on the condition of mass data and confined memory.
