Mastering Spatial Data in R: TidyCensus, PMTiles, & AI with Kyle Walker

mardi 17 février 2026 • Durée 50:31

In this episode of the Spatial Stack, Matt sits down with Kyle Walker, Professor of Geography at TCU and the creator of popular R packages like tigris and tidycensus.

Kyle dives into why he views US Census data as critical infrastructure and how open data is fundamentally transforming decision-making across industries like real estate and energy. He shares the origin story of his open-source work, explaining why he champions the R programming language for full-stack geospatial analysis. The conversation also covers the evolution of web mapping, from the laborious process of rendering dot-density maps to the blazing-fast performance of modern tools like PMTiles.

Finally, Kyle reveals how generative AI specifically Claude Code and the Zed editor is serving as his ultimate coding assistant, allowing him to rapidly build complex projects like the mapgl package and turn his ideas into reality faster than ever.

#40: The "GPT Moment" for Earth: Moving from Computer Vision to Large Earth Models

mercredi 11 février 2026 • Durée 59:49

We have never had more data about our planet: petabytes of satellite imagery, aerial photos, and sensor readings collected daily. Yet, turning that massive volume of "noise" into a clear signal remains the fundamental challenge of the geospatial industry.

In this episode of the Spatial Stack, I sit down with the engineering and product minds from Wherobots: Ryan, Phil, and Len - to tear down the architecture required to handle Earth Observation data at a planetary scale. We move beyond the buzzwords to discuss the engineering "war stories" of building resilient inference pipelines.

We dive deep into why the industry is moving away from simple computer vision toward "Large Earth Models" that function like LLMs for the physical world. We also get into the weeds of the tech stack: the battle between Dask and Ray for distributed compute, why Cloud-Optimized GeoTIFFs (COGs) aren't always the answer for inference, and how formats like Zarr are unlocking multidimensional analysis.

In this episode, we cover:

The Data Bottleneck: Why "garbage in, garbage out" is still the biggest hurdle in monitoring a changing planet.

Infrastructure Realities: The specific limitations of Google Earth Engine and why we needed a cloud-agnostic approach.

Engineering Pivot: Why Wherobots migrated from Dask to Ray to solve "crashing cluster" syndromes and memory management issues.

The Future of GeoAI: How embeddings and foundation models are compressing petabytes of data into searchable, semantic insights.

The Hidden Data Crisis in GIS (And How to Solve It)

Épisode 12

mercredi 26 mars 2025 • Durée 48:02

📩 Get every update from my newsletter ➡️ https://forrest.nyc ⬅️

What if you could stop wrangling geospatial data, and just get to the good part?

In this episode, I sit down with Rob Fletcher, Chief Science Officer at Seer AI, to talk about one of the biggest blockers in geospatial today: accessing and integrating the right data, at the right time, in the right format.

Rob shares his journey from doing particle physics at CERN to pioneering spatial data infrastructure, and how Seer AI is building what he calls a “CDN for geospatial data.”

We dive into:

🌍 Why the biggest challenge in GIS isn’t analysis—it's finding and formatting data
💡 The danger of agreeing to analytics projects without knowing what's possible
🛠️ Why Seer AI chose graph technology to organize spatial data across sources
⚡ How a "side project" dashboard became essential to real-time disaster response
📊 Bridging the gap between GIS teams and business analysts

Whether you're working in local government, disaster response, sustainability, or just tired of managing messy spatial data, this episode will change how you think about building modern GIS workflows.

#32: Why Meta Is Betting Big on Open Maps

Épisode 32

jeudi 4 décembre 2025 • Durée 45:46

Meta has more than 3 billion users across Instagram, WhatsApp, and even its new AR glasses. Behind the scenes, all of them are powered by one thing: maps. But instead of relying on closed systems, Meta is betting big on open data—and building its own global map.

In this episode, I talk with Said Turksever from Meta, who leads their open mapping strategy. We dive into:

🌍 Why Meta cares so much about maps
🛠 The tools they’re building with AI and open source
🏙 How cities from Phoenix to Naples are being transformed by open data
🚶 The future of pedestrian mapping and accessibility
🤝 The role of communities in shaping the next generation of maps

From disaster response to daily navigation, the impact of open mapping stretches far beyond social media. This is a conversation about technology, community, and the future of how we navigate the world.
