#30: A5: The Global Grid System Changing How We Map the World with Felix Palmer

In this episode, I sit down with Felix Palmer, creator of A5, a new global grid system that’s redefining how we represent and analyze the Earth.Felix shares how a 1980s math paper led him to build a pentagon-based global grid, one that fixes the distortions found in systems like H3 and S2, achieving true equal-area cells across the entire planet.We discuss the geometry behind A5, the trade-offs of global gridding, and why visual design and spatial computation are deeply connected.If you’ve ever worked with spatial indexes or wondered how we might rebuild the geometry of the globe itself, this episode will change the way you see maps.We cover:The origins of A5 and how it compares to H3Why equal-area grids matter for accurate analysisThe visual and geometric challenges of mapping a sphereA5 Website: https://a5geo.org/A5 on GitHub: https://github.com/felixpalmer/a5🚀 Ready to move beyond desktop GIS?Step into the Spatial Lab: a global community for ambitious geospatial professionals who want to break out of outdated workflows and join the top 5% of the field.👉 Join Spatial Lab: https://forrest.nyc/spatial-lab/🎓 Want structured, career-changing learning?🚀 Modern GIS Accelerator: https://forrest.nyc/accelerator/ — master Python, Spatial SQL & cloud workflows in 2 weeks🧭 Career Compass: https://forrest.nyc/career-compass/ — fast, practical steps to land the GIS role you want🪄 AI Copilot for GIS: https://forrest.nyc/ai-copilot-for-gis/ — learn to integrate AI into your geospatial workflows & boost your productivity📰 Weekly modern GIS insights: https://forrest.nyc⚡️ Spots for the next live cohort and mentorship cycle are closing soon,  join now to lock in your place and momentum.CONNECT WITH ME📸 Instagram:  https://www.instagram.com/matt_forrest/💼 LinkedIn: https://www.linkedin.com/in/mbforr/📧 Newsletter: https://forrest.nyc🌐 Website: https://forrest.nyc

How Mapbox is Quietly Powering the AI Map Revolution with Kieran McCann

AI can answer almost anything, except “where.” That gap is huge, and  Kieran McCann from Mapbox is working to close it.In this episode of The Spatial Stack, Matt sits down with Kieran, who’s spent six years helping Mapbox quietly power some of the most widely used maps and location services in the world. From his early days doing grunt map edits at Apple Maps to shaping Mapbox’s next big bet: AI-native mapping. Kieran shares what it takes to bring true spatial understanding into artificial intelligence.You’ll hear how Mapbox is experimenting with ways for AI to finally reason about place and direction, what’s still missing for models to “get” geography, and how anyone, even those just starting out, can build powerful AI + geospatial tools today. Kieran also breaks down how showing prototypes can change your career trajectory and why now is the perfect time to jump into this space.If you’re curious about where mapping and AI collide and what that means for your work, your career, and the apps we all use every day, this conversation is a must-listen.🚀 Ready to move beyond desktop GIS?Step into the Spatial Lab: a global community for ambitious geospatial professionals who want to break out of outdated workflows and join the top 5% of the field.👉 Join Spatial Lab: https://forrest.nyc/spatial-lab/🎓 Want structured, career-changing learning?🚀 Modern GIS Accelerator: https://forrest.nyc/accelerator/ — master Python, Spatial SQL & cloud workflows in 2 weeks🧭 Career Compass: https://forrest.nyc/career-compass/ — fast, practical steps to land the GIS role you want🪄 AI Copilot for GIS: https://forrest.nyc/ai-copilot-for-gis/ — learn to integrate AI into your geospatial workflows & boost your productivity📰 Weekly modern GIS insights: https://forrest.nyc⚡️ Spots for the next live cohort and mentorship cycle are closing soon,  join now to lock in your place and momentum.CONNECT WITH ME📸 Instagram:  https://www.instagram.com/matt_forrest/💼 LinkedIn: https://www.linkedin.com/in/mbforr/📧 Newsletter: https://forrest.nyc🌐 Website: https://forrest.nyc

Turning GIS into ROI, One Stock at a Time

What happens when a geospatial professional decides to map the entire business of our industry?In this episode of Spatial Stack, Matt talks with Wilfred Waters, the creator of the first-ever Geospatial Index, a hand-built list tracking hundreds of public companies shaping maps, data, satellites, sensors, and spatial software. Will shares how he spent countless late nights pulling together every geospatial stock he could find, from Vietnam to Finland to the U.S., and what the process revealed about where the industry is heading.Along the way, we unpack how indexes work, why understanding the business side of geospatial matters (even if you’re not an investor), and how seeing the market clearly can help you think differently about your own career and the technologies you rely on.Geospatial FM on Spotify: https://open.spotify.com/show/5gpQUsaWxEBpYCnypEdHFCOn Apple Podcasts: https://podcasts.apple.com/us/podcast/geospatial-fm/id1674368928Substack: www.geospatial.fmIndex introduction and construction rules: https://www.geospatial.fm/p/compounding2024 Year In Review: https://www.geospatial.fm/p/2024-geospatial-stocks-performance⚠️ Nothing in this episode is investment advice.

The End of Expensive Space Data: NOVI’s Vision for Earth Observation

What if satellites became as smart and as accessible as your smartphone?In this episode, I sit down with Michael Bartholomeusz, CEO of NOVI to unpack how Earth observation is being transformed by edge computing in space. We explore the shift from sending terabytes of raw imagery to delivering actionable insights, and why this change could take the cost of analysis from $150,000 down to under $1,000.Michael shares stories from his 25-year career, from working on the space shuttle that launched John Glenn, to leading NOVI’s dual-use strategy for defense and commercial markets. Along the way, we dive into:Why the current Earth observation model is brokenHow edge computing flips the economics of space dataThe “iPhone moment” for satellites and what it means for new applicationsReal-world examples of cost savings and new use casesThe industries poised to benefit most — from defense to agriculture to disaster responseThis is a conversation about more than satellites.

Why Open Data Isn’t Really Open: Navigating Licenses in Geospatial with Mina Nada

Open data is supposed to unlock innovation, but what happens when “open” isn’t really open?In this episode of The Spatial Stack, I sit down with return guest Mina Nada to explore the world of open data licenses — from Creative Commons to Open Database Licenses and beyond. We break down what these licenses actually allow you to do, where the pitfalls are, and how they impact anyone building geospatial products, tools, or services.Along the way, Mina shares real-world experiences navigating licensing challenges, from NASA’s permissive CC0 approach to the more restrictive “share-alike” models. Whether you’re a developer, analyst, or entrepreneur, this conversation will help you understand how to work with open data without running into legal or business roadblocks.If you’ve ever wondered what “open data” really means for your projects, this is the episode to listen to.The future is spatial — so let’s get into it.

An Honest Conversation About Imposter Syndrome in GIS

In this episode, I open up about something many of us in GIS rarely talk about — imposter syndrome. That nagging feeling of not being good enough, of questioning whether you really belong in this field, even when the evidence says otherwise.This isn’t a polished success story, it’s an honest conversation about doubt, comparison, and the pressure to measure up in GIS. I share my own experiences, what I’ve learned along the way, and why so many professionals quietly wrestle with the same thoughts.If you’ve ever wondered “Am I really cut out for this?” — you’re not alone. Let’s talk about it.
