A fast native desktop app to open, inspect, fix and query GeoParquet. Opens datasets too heavy for other tools, grades every file against best practices, rewrites slow files in one click, runs spatial SQL on local and remote data. Pure Rust, no server, no GDAL, for macOS, Windows and Linux.

Things I'm currently building and contributing to, beside private contracts and consulting work. All open source, all cloud-native, all focused on making geospatial data easier to use and more accessible.
Free daily GeoParquet 2.0 snapshots of OpenStreetMap data for the US, Canada, and Mexico: 98 regions × 16 themes, queryable straight from a URL with DuckDB. No downloads, no account, cloud-native by design.
On-demand exploration of climate risk indicators across the whole world: heat, drought, flood, and vegetation stress, served from a cloud-native geospatial stack and designed for non-specialist decision makers.
Standalone async Sentinel-2 COG tile server. Renders Sentinel-2 scenes as XYZ tiles on demand, reading Cloud Optimized GeoTIFFs directly from object storage, with no pre-rendering, no database, and a minimal footprint.
The pipeline behind the GeoParquet site: converts Geofabrik OSM PBF extracts into state-partitioned, theme-filtered GeoParquet 2.0 files. Reproducible snapshots, tunable themes, open source.
