Episodes
Smart Point Clouds: What If Every Point Knew What It Was
Point clouds still feel a little bit like magic to me. You walk through a room, a city, or even just your living room with a scanner or your phone, and you can recreate it afterwards. But on their own, point clouds aren't actually that smart. So what would it mean for every single point to know not just where it is, but what it is, and how it relates to everything around it?
My guest this week is
Cloud-Native Geospatial for Small Teams
Cloud-Native Geospatial for Small Teams: How the Utah Geological Survey Did It
What happens when a small, technical team at a state agency decides to go cloud native? They don't have terabytes of satellite imagery. They have lots of small datasets, lots of scientists and lots of people who just want to get at the data.
In this episode, I talk with Marshall Robinson and Clinton Lunn from the Data M
GERS, Metadata, and Maps Built for Machines
We already have a map. Actually, we have lots of maps. So why did Overture build another one?
My guest in this episode is Amy Rose, CTO of the Overture Maps Foundation, and she makes a pretty compelling case. Overture isn't trying to replace OpenStreetMap — it sits downstream from it, and from hundreds of other sources, doing the unglamorous work of standardising all of that into something you can
The Evolution of Positioning Systems
Republished Episode - I wanted to resurface this episode because positioning is everything, and it's a great overview of how it works.
Right now you are being bathed in radio signals from about 35 satellites, each one 20,000 km away, and every one of them is weaker than the noise floor of the receiver trying to hear it. That is GNSS, and it is the only technology on Earth that can tell you where
Sentinel Bird
Earlier this year I ran a small experiment called the Geospatial Launchpad — six weeks of working closely with a couple of people to help them push their geospatial projects forward. West was one of them.
His project is Sentinel Bird (sentinelbird.com): an archive of every Sentinel-2 visit over the Gaza Strip since 2015, with 10-meter resolution imagery for each district, interactive comparison sl
Fields Of The World
Where does one field end and the next one begin? It sounds trivial right up until you try to answer it.
In this episode, I'm joined by Hannah Kerner — Assistant Professor at Arizona State University, AI Lead for NASA Harvest and NASA Acres, and Research Advisor for Taylor Geospatial — to talk about Fields of the World.
This episode is sponsored by the Cloud Native Geospatial Forum. The CNG Forum
Virtual Worlds for Physical AI Systems
In this episode I'm joined by Apurva Shah, co-founder and CEO of Duality AI, a company building virtual worlds — or "world models" for robots and physical AI systems.
Apurva's path here is an unusual one. He spent most of his career in animation, first at Pacific Data Images (which later became DreamWorks) and then over a decade at Pixar. His co-founder, Mike Taylor, comes from the other end of th
GPS, But 100 Times Stronger
My guest today is Tyler Reid, co-founder and CTO of Xona, a company building the first commercial satellite navigation system.
We get into why Tyler and his team are moving satellites into low Earth orbit and what that unlocks. Stronger signals that can penetrate indoors, more resilient timing infrastructure, and better security against jamming and spoofing.
GPS sits 20,000 kilometres out. Xona si
Turning Aerial Imagery Into a Searchable World
Vexcel isn't a household name — but you've almost certainly used their data. This aerial imaging company flies low-elevation aircraft across roughly 45 countries, capturing imagery at 7.5cm resolution from five different angles (straight down plus four oblique views), building one of the richest geospatial datasets on Earth.
In this episode, Daniel talks with Steve Lombardi, VP of Product at Vexce
Cloud Native for the Rest of Us
What happens when you take cloud native geospatial out of the satellite-and-petabyte world and drop it into a small city with no budget and the world's slowest internet connection?
In this episode, Daniel talks with Nissim Lebovits, a city planner turned geospatial data scientist, about his nine months in Argentina building climate risk tools for under-resourced municipalities. Nissim breaks down
Mapping With 360 Cameras
Jeffrey Martin is the co-founder and CEO of Mosaic, a company building 360-degree camera systems designed specifically for mapping. He's been obsessed with 360 imagery for over 20 years — he built one of the first websites combining panoramic images with a map back in 2005, before Google Street View existed, and he holds a Guinness World Record for a 320-gigapixel image of London stitched together
Who Pays for Open Source?
Open source software runs a huge chunk of the geospatial world — but somebody still has to pay for it.
In this episode I sit down with Marco Bernasocchi creator of QField and CEO of OpenGIS.ch, to dig into the awkward question most open source projects avoid: how do you keep something free and open while paying real people to build and maintain it?
Marco has been in the open source world since 200
The Great Retooling
Ian Schuler is the CEO of Development Seed — the team behind a lot of the open source tooling that quietly holds up the geospatial world. He's been at the helm for over a decade, and in this conversation, we dig into what he calls the great retooling: the idea that cloud-native geospatial is about to flip from an emerging pattern to the dominant one, and that AI is the thing tipping it over the ed
Earth Observation - The Invisible Industry
What is Earth observation, really — and why, after fifty years of satellite imagery, is it still not "mainstream"?
In this episode, I'm joined by Aravind Ravichandran, founder of TerraWatch, an independent research and advisory firm focused entirely on Earth observation. Aravind writes the TerraWatch newsletter, runs the EO Summit, and spends his time thinking about the strategy and economics of t

AI in QGIS
I've been playing around with a lot of large language models lately, and it is absolutely fascinating to watch them work. But what happens when you bring that directly into QGIS?
Right now, AI in the geospatial industry is a lot like a fast, enthusiastic new intern, incredibly helpful, and sometimes completely wrong, but improving at a rate that no human can compete with.

Geospatial Makers Start Building!
Geospatial Product Swiss Army Knife
1. The "Build It and They Won't Come" Trap
We have all seen it: a talented geospatial professional spends months—perhaps years—perfecting a technically sophisticated web map or a niche data service, only to release it to a deafening silence. In our industry, the "build it and they will come" philosophy is a fast track to zero traction.

Vibe Coding and the Fragmentation of Open Source
Why Machine-Writing Code is the Best (and Most Dangerous) Thing for Geospatial:
The current discourse surrounding AI coding is nothing if not polarized. On one side, the technofuturists urge us to throw away our keyboards; on the other, skeptics dismiss Large Language Models (LLMs) as little more than "fancy autocomplete" that will never replace a "real" engineer. Both sides miss the nuanced re
A5 Pentagons Are the New Bestagons
How can you accurately aggregate and compare point-based data from different parts of the world? When analyzing crime rates, population, or environmental factors, how do you divide the entire globe into equal, comparable units for analysis?

The Sustainable Path for Open Source Businesses
The Open-Source Conundrum
Many successful open-source projects begin with passion, but the path from a community-driven tool to a sustainable business is often a trap.
The most common route—relying on high-value consulting contracts—can paradoxically lead to operational chaos. Instead of a "feast or famine" cycle, many companies find themselves with more than enough work, but this success com
Free Software and Expensive Threats
Open-source software is often described as "free," a cornerstone of the modern digital world available for anyone to download, use, and modify. But this perception of "free" masks a growing and invisible cost—not one paid in dollars, but in the finite attention, time, and mounting pressure placed on the volunteer and community maintainers.
This hidden tax is most acute when it comes to security
Mapping Your Own World: Open Drones and Localized AI
What if communities could map their own worlds using low-cost drones and open AI models instead of waiting for expensive satellite imagery?
In this episode with Leen from HOT (Humanitarian OpenStreetMap Team), we explore how they're putting open mapping tools directly into communities' hands—from $500 drones that fly in parallel to create high-resolution imagery across massive areas, to predictive
From Data Dump to Data Product
This conversation with Jed Sundwall, Executive Director of Radiant Earth, starts with a simple but crucial distinction: the difference between data and data products. And that distinction matters more than you might think.
We dig into why so many open data portals feel like someone just threw up a bunch of files and called it a day. Sure, the data's technically "open," but is it actually useful? J
