Earth observation and simulation are generating large volume of geospatial raster data at an unprecedented growth. However, the large data volume and complex contend pose grand challenges for both data engineers and data scientists to efficiently processing and analyze these data. This paper proposes a Spark-based framework with Hadoop Distributed File System (HDFS) to improve the efficiency of geospatial raster data processing in parallel, and also integrate Tensorflow to support CNN-based image processing models. The experiment results demonstrate that the proposed system could not only provide a scalable fashion to query big geospatial raster images, but also speed up the CNN-model inference processing.
