Processing Massive-Scale Geospatial Data with Apache Sedona
2021-09-29, 15:30–16:00, Humahuaca

Apache Sedona is a cluster computing system for processing large-scale spatial data. Sedona provides a set of out-of-the-box Spatial Resilient Distributed Datasets and Dataframes that can efficiently load, process, and analyze large-scale spatial data across a cluster of machines. In the talk, we will give an overview of the Apache Sedona architecture. We will then demonstrate Sedona’ s Scala, SQL, and Python APIs to program analytics pipelines on-top of geospatial data.

The talk presents the details of designing and developing Apache Sedona, which extends the core engine of Spark and SparkSQL to support spatial data types, indexes, and geometrical operations at scale. The talk also gives a detailed analysis of the technical challenges and opportunities of extending Spark to support state-of-the-art spatial data partitioning techniques: uniform grid, R-tree, Quad-Tree, and KDB-Tree. The talk will explain how building local spatial indexes, e.g., R-Tree or Quad-Tree, on each Spark data partition can speed up the local computation and hence decrease the overall runtime of the spatial analytics program. Extensive experiments on real spatial datasets show that Sedona achieves up to two orders of magnitude faster run time performance than existing Hadoop-based systems and up to an order of magnitude faster performance than Spark-based systems.
