Summit 2021 Manipulating Geospatial Data at Massive Scale

May 27, 2021 04:25 PM PT

John Deere ingests petabytes of precision agriculture data every year from its customers' farms across the globe. In order to scale our data science efforts globally, our data scientists need to perform geospatial analysis on our data lake in an efficient and scalable manner. In this talk, we will describe some of the methods our data engineering team developed for efficient geospatial queries including:

- Leveraging Quadtree spatial indexing to partition our Delta Lake tables

- Extending the Spark Catalyst Optimizer to perform efficient geospatial joins in our data lake
