A hierarchical indexing strategy for optimizing Apache Spark with HDFS to efficiently query big geospatial raster data
Earth observations and model simulations are generating big multidimensional array-based raster data. However, it is difficult to efficiently query these big raster data due to the inconsistency among the geospatial raster data model, distributed physical data storage model, and the data pipeline in...
