Talking Postgres with Claire Giordano Why people care about PostGIS and Postgres with Paul Ramsey & Regina Obe
The geospatial world of Postgres is so much more than mapping. Paul Ramsey and Regina Obe join Claire Giordano and Pino de Candia to explore the "where" on Path To Citus Con*, the podcast for developers who love Postgres. What are some of the unexpected use cases for PostGIS, one of the most popular extensions to Postgres? How have Large Language Models helped in the geospatial world? Can you really model almost anything with pgRouting? “Where” is the universal foreign key. They talk about communities and governments using geospatial data and how it's very difficult to build a database that does not have some sort of spatial component to it. Why do people care about PostGIS? Find out more about OpenStreetMap and its place in the open source geospatial world. Finally, Paul and Regina share the origin story for the PostGIS extension to Postgres.
*[Update: July 2024] Path To Citus Con has been renamed to Talking Postgres. All of the past podcast episodes from Path To Citus Con—now called Talking Postgres with Claire Giordano—can be found here: https://talkingpostgres.com
