What it runs on
A deliberately small set, chosen once and reused. Everything below is in production across the work above — none of it is aspirational.
- Cloudflare Pages
- Static hosting with per-branch preview deploys. Every project in the record is served from it.
- Cloudflare Workers
- Request-time compute at the edge — APIs, scheduled ingest, and rendering where it earns its keep.
- Cloudflare D1
- SQLite at the edge. The EPSG registry is 13 MB of it; the largest conflict timeline runs to 72 MB.
- PostgreSQL & PostGIS
- Where the geometry is the workload. Temporal schemas, spatial indexes, and role separation enforced by the database.
- PDAL, GDAL & Python
- The point-cloud and raster toolchain, driven from applications rather than reimplemented inside them.
- Access control in the data layer
- Redaction applied once in restricted views, so it reaches tiles, API and exports alike. No code path can forget it.
- Client-side processing
- Where data is sensitive the work happens in the browser, and there is no endpoint to send it to.
- Static-first
- HTML that is already HTML. Frameworks appear when state demands them, not by default.
