Abstract
In distributed file systems, the integral management of large and small files is very important for the performance of applications. Based on Google File System, we present a framework of distributed file system to improve the management of geospatial objects. By adopting the access locality and spatial relationships among geospatial objects, we extend the metadata in the master node and add spatial indices in the data nodes. An optimized strategy is also proposed to unify the management of spatial data from multi-sources. Our experience shows that the method is available for managing geospatial data.
