Relationship between Apache Sedona and Wherobots
Wherobots uses Apache Sedona as an open core to build a cloud data platform optimized for geospatial analytics and AI workloads. Wherobots offers a streamlined experience for executing geospatial workloads, powered by Apache Sedona. Wherobots Inc. was founded by the original creators of Apache Sedona. As an open-source project, Apache Sedona attracts contributions from various leading companies, including Wherobots. Wherobots actively contributes to the development and improvement of Apache Sedona and also develops additional optimizations and proprietary features that enhance and extend the capabilities of Apache Sedona, such asWherobotsDB, a full-fledged spatial analytics database system.

In Figure 16a, GeoSpark distance join query runs around 7x - 9x faster than Simba, a spatial extension on Spark, on 1 - 24 core machines.

GeoSpark comes close to a complete spatial analytics system. It also exhibits the best performance in most cases.
