Big Data Geospatial SQL Without SQL Geospatial Support

image02In geospatial queries, we often need to quickly find all the points of interests (POIs) within a certain distance from an anchor point. In this post, we present a simple method that scales very well for billions of data points and implemented using plain SQL; so it can be deployed on a massive data processing systems like Redshift or Hive/SparkSQL on Hadoop without utilizing any geospatial support components.
