TL;DR: GeoETL v0.7.0 adds 29 new spatial SQL functions including predicates (ST_Intersects, ST_Contains), geometry generators (ST_Buffer, ST_ConvexHull), validators (ST_IsValid), and accessors (ST_X, ST_Y).
TL;DR: GeoETL v0.5.0 adds spatial UDFs (ST_Distance, ST_Point, ST_GeomFromText) powered by GEOS for spatial operations in SQL queries during conversion.
In our previous posts, we introduced GeoETL and showed you how to perform your first data conversion. Now, let's take a deeper look under the hood and explore the architecture that makes GeoETL a powerful and high-performance geospatial ETL tool.
