Along with globalization of our societies comes the need to analyze the geospatial and geotemporal data that is needed to manage the growth in commerce, communications, and other activities. In order to make geospatial analytics more maintainable and scalable there has been an increase in the number of database engines that provide extensions to their SQL syntax that supports manipulation of spatial data. In this episode Matthew Forrest shares his experiences of working in the domain of geospatial analytics and the application of SQL dialects to his analysis.
Your data platform needs to be scalable, fault tolerant, and performant, which means that you need the same from your cloud provider. Linode has been powering production systems for over 17 years, and now they’ve launched a fully managed Kubernetes platform. With the combined power of the Kubernetes engine for flexible and scalable deployments, and features like dedicated CPU instances, GPU instances, and object storage you’ve got everything you need to build a bulletproof data pipeline. If you go to dataengineeringpodcast.com/linode today you’ll even get a $100 credit to use on building your own cluster, or object storage, or reliable backups, or… And while you’re there don’t forget to thank them for being a long-time supporter of the Data Engineering Podcast!
Have you ever woken up to a crisis because a number on a dashboard is broken and no one knows why? Or sent out frustrating slack messages trying to find the right data set? Or tried to understand what a column name means?
Our friends at Atlan started out as a data team themselves and faced all this collaboration chaos themselves, and started building Atlan as an internal tool for themselves. Atlan is a collaborative workspace for data-driven teams, like Github for engineering or Figma for design teams. By acting as a virtual hub for data assets ranging from tables and dashboards to SQL snippets & code, Atlan enables teams to create a single source of truth for all their data assets, and collaborate across the modern data stack through deep integrations with tools like Snowflake, Slack, Looker and more.

- Your host is Tobias Macey and today I’m interviewing Matthew Forrest about doing spatial analysis in SQL
- How did you get involved in the area of data management?
- Can you describe what spatial SQL is and some of the use cases that it is relevant for?
- compatibility with/comparison to syntax from PostGIS
- What is involved in implementation of spatial logic in database engines
- mapping geospatial concepts into declarative syntax
- foundational data types
- data modeling
- workflow for analyzing spatial data sets outside of database engines
- translating from e.g. geopandas to SQL
- level of support in database engines for spatial data types
- What are the most interesting, innovative, or unexpected ways that you have seen spatial SQL used?
- What are the most interesting, unexpected, or challenging lessons that you have learned while working with spatial SQL?
- When is SQL the wrong choice for spatial analysis?
- What do you have planned for the future of spatial analytics support in SQL for the Carto platform?
- From your perspective, what is the biggest gap in the tooling or technology for data management today?
- Thank you for listening! Don’t forget to check out our other show, Podcast.__init__ to learn about the Python language, its community, and the innovative ways it is being used.
