An integration token used to be bound to the resource list that existed when it
was minted, so every new basemap needed a fresh token. read_all grants read on
every basemap and vector, including ones catalogued later, which is what an
internal consumer of the whole catalogue actually wants.
Tokens also gain a way to opt out of the default lifetime: expires_at accepts
never (or 0) in the API and the console, producing a token with no expiry.
The console shows blanket access as a badge instead of an empty grant list, and
the token form exposes both new options.
A Go service that scans existing basemap tile directories and vector files,
catalogues them in SQLite, issues scoped access tokens, and serves tiles and
downloads to downstream systems. It deliberately does not generate or process
raster data: GIS software produces the tiles, this service catalogues,
authorises and distributes them.
Capabilities
- scans basemap tile directories (manifest-based or raw z/x/y) and vector
assets (.geojson, .json, .zip, shapefiles with sidecars)
- token auth with per-resource grants, expiry and coarse scopes (read, slice)
- resource health inspection flags a moved or deleted tile root before a client
hits a 404
- downstream push with exponential-backoff retries and manual re-queue
- image slicing jobs driven by the GDAL bundled with QGIS, including VRT
mosaicking so successive drone flights accumulate into one seamless layer
- a narrow, non-admin slicing API for external callers: submit, poll,
idempotent by job code, completion callback
- ops console covering health, ledger, tokens, pushes, scans, slicing and
service info
- native Windows service install/start/stop with crash recovery, auto-start and
a rotating log file, so no NSSM or WinSW wrapper is needed
Verified with 49 tests plus live runs against real tile data and real GDAL.
