Scale Your Spatial Analysis By Building It In SQL With Syntax Extensions

Data Engineering Podcast - Un pódcast de Tobias Macey - Domingos

Categorías:

Summary 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. Announcements Hello and welcome to the Data Engineering Podcast, the show about modern data management When you’re ready to build your next pipeline, or want to test out the projects you hear about on the show, you’ll need somewhere to deploy it, so check out our friends at Linode. With their managed Kubernetes platform it’s now even easier to deploy and scale your workflows, or try out the latest Helm charts from tools like Pulsar and Pachyderm. With simple pricing, fast networking, object storage, and worldwide data centers, you’ve got everything you need to run a bulletproof data platform. Go to dataengineeringpodcast.com/linode today and get a $100 credit to try out a Kubernetes cluster of your own. And don’t forget to thank them for their continued support of this show! 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 Interview Introduction 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?
