When most people think of relaxing, they picture a walk, a movie, or a quiet evening. For Dr. Qiusheng Wu, relaxation means writing code. As he puts it, “When I have free time, when I’m relaxing, I’m coding. If you’ve ever used Leafmap, explored GeoAI, or watched one of his tutorials on YouTube, you already […]
SedonaDB vs DuckDB vs PostGIS: Which spatial SQL engine is fastest?
Last week the team from Apache Sedona released SedonaDB, a new tool that makes spatial processing fast and also treats spatial data like a first class citizen. Or read a different way it is really fast for doing spatial analytics. It uses Python and SQL to analyze data and can also output data in GeoParquet […]
Spatial Data Lakehouse Architecture: Beyond H3 and Vector-Only Data
Storage and formats are the foundation. Pipelines make them practical. But storage and processing architectures determine what’s actually possible at scale. We’ve talked about cloud storage enabling modern geospatial workflows and the formats that make data queryable. We’ve covered the pipelines that get your data into those formats. But there’s a bigger architectural question that […]
The Modern Geospatial Data Stack: Trends, Tools, and What They Mean for You
The geospatial technology landscape is changing fast. What used to be a world of shapefiles, desktop software, and siloed workflows is now becoming cloud-native, AI-driven, and analytics-focused. This shift isn’t just technical—it’s reshaping how geospatial professionals build, analyze, and share data. In this post, I’ll break down the key trends shaping the modern geospatial data […]
Why your spatial pipelines are probably broken (And how Airflow can help)
In the world of spatial data, building pipelines often feels like duct-taping together cron jobs, brittle scripts, and whatever cloud service happens to be in reach. Whether you’re transforming geospatial imagery, generating features for machine learning, or managing time-sensitive datasets like weather and river gauges chances are, your pipelines could use an upgrade. In the […]
