From PostgreSQL to the Cloud: Setting up a Spatial Data Infrastructure in BigQuery

Migrating from PostgreSQL to BigQuery for geospatial analytics offers several benefits, including scalability, performance, and security. The traditional database approach has limitations, such as a lack of compute-storage separation, complexity when scaling, sharing limitations, and high costs associated with storing large spatial datasets. Cloud data warehouses like BigQuery provide unparalleled levels of scalability, performance, and security. With the Spatial Extension for BigQuery, users can unlock a toolbox of over 100 user-defined functions and routines for advanced spatial analytics. By following a step-by-step guide using CARTO, organizations can easily migrate their geospatial analysis workflows to BigQuery, simplifying data sharing, and reducing costs. The process involves setting up the spatial data infrastructure in BigQuery, importing data from PostgreSQL, spatially clustering data tables, accelerating queries with the BI Engine, sharing data with external users, and performing spatial analysis and visualization using CARTO.
