Tools

• get_dataset_part ~105 tokens
  The URL of one part of a dataset as GeoJSON, plus its description. Fetch the URL for the features; parts can be several megabytes.
• get_layer ~640 tokens
  One map layer as a GeoJSON FeatureCollection: one point per place with the reading on the date (else the latest observed before it, never a guess), or one point per event for event layers.
• get_readings ~558 tokens
  Fetch current readings from one source, each with value, unit, a one-line summary, place and provenance (source, URL, fetch time, licence). Sources this server will not republish (non-commercial, restricted or unreviewed licence) answer with an error naming the licence.
• get_source ~45 tokens
  One catalogue entry in full.
• list_datasets ~91 tokens
  Static public datasets this server holds as GeoJSON (wildfire burn perimeters, public-land share by county, federal campgrounds, fire-weather stations), with source, licence, feature count and parts (one per state, or "all").
• list_hubs ~69 tokens
  Projects and catalogues that collect sources (God's Eye View, World Monitor, the MCP Registry, Source Cooperative, ...), with how each relates to this one.
• list_layers ~60 tokens
  Map layers this server can draw as GeoJSON, with unit, source, licence, whether it is available here, and how to read it.
• list_places ~64 tokens
  Named places the fetchers read for, with their upstream ids (CO-OPS station, USGS gauge, eBird region) and tags.
• search_sources ~222 tokens
  Search the catalogue of public data sources (weather, water, hazards, flights, ships, energy, filings, trade, ...). Each entry gives the API, coverage, cadence, auth needed and licence. Use it to find where a kind of data comes from before writing a fetcher.
