What you upload. Files are the raw material — run a job against one to turn it into a table or a tile.

Each upload of this file is a version. Jobs run against a specific one, so older versions are kept.

Jobs turn this file into something the map can draw — a parquet table, or GeoTIFF tiles.

Re-run a job on a timer, for data that changes at the source — a nightly feed, a weekly extract.
