Issue 20 - Introduction to GeoJSON

Welcome to another edition of this newsletter. I’m Daniel Imfeld, and here I share things I’ve read recently, updates on what I’ve been working on, and occasionally nascent blog post drafts.

Over the weekend I published the first article in my new geographic data series. This one is an Introduction to GeoJSON, which goes over the different ways that GeoJSON can represent data.

This is geared toward newcomers to the geographic data world, but it sets the stage for future articles which will build upon this base. Some of the future topics:

  • Using geographic data in a database
  • Manipulating it inside the database with PostGIS and similar solutions
  • Altering and combining geography shapes
  • Converting and importing data from various sources
  • Compressing GeoJSON using TopoJSON
  • Making map-based web apps

Watch this space for progress reports and previews of the content as it takes shape. And of course, I’m taking suggestions for more topics. What would you like to learn about?

Links and Reading

This article on rollback netcode is a nice overview of some different ways of synchronizing state when latency and timing really matters. Mostly only useful for game programming, but well explained.

If you enjoyed this, I’d love if you share it with a friend (sign up here) or just reply to this email with your thoughts. Thanks for reading!
