Workflow for getting IceNet data onto map

This is a documentation thing which spans multiple APIs but the tricky bits are on GeoServer...

Inputs: 2 daily netCDFs (one for each hemisphere), approx 100mb each - rolling composites of ice forecast data

  • API token generated with charon
  • Initial push to files API (POST), set public=true
    • Successive pushes update the file content via their IDs (PUT)
  • Ingestion into GeoServer via its own API calls
    • Creation of a new BAS user with the right permissions?
    • How to import?
      • From files API via URL?: Nope, NetCDF url only supports local files
      • By mounting files API files into geoserver and accessing directly?: Nope, files API stores files gzipped, so geoserver can't read them
        • Do we allow writing some files as ungzipped? Would rather not - adds complexity to files API, more disk used
      • An extra API running in geoserver container?: Nope, would need to refresh on Java and how to develop a Tomcat app
      • An extra, hidden endpoint on the files API, to write the decompressed file to another directory, and then read that?: Seems like the quickest thing to do right now. Could also add a ?decompress=true argument for the POST and PUT arguments.
    • (How to / do we) tell it to reproject the layer(s)?
    • (How to / do we) tell it to re-import the files when they're updated?
  • Creation of layers on map service which point to the tiled layers via GeoWebCache

Send details of how to do these steps to James Byrne jambyr@bas.ac.uk
