Abstract本申请涉及一种面向Spark的遥感数据索引方法、系统及电子设备。所述包括:在PostgreSQL数据库中分别建立遥感数据的四叉树、GeoHash和R树索引系统,并将所述四叉树、GeoHash和R树索引系统进行分别存放,得到面向Spark多索引共存的多索引存储系统;选择索引策略选择器,建立Spark与所述多索引存储系统的对接;基于所述索引策略选择器,根据计算场景分配对应的索引方式,根据所述索引方式在所述多索引存储系统中查找遥感数据。本申请能够根据不同计算场景分配索引方式,使索引时间相对于单一的索引方式大幅度下降,并且适应Spark计算任务,快速高效的索引到所需文件,实现遥感数据的高效计算。
