  • get_dataset_partThe URL of one part of a dataset as GeoJSON, plus its description.No findings

    Why it is in this group

    • The name "get_dataset_part" says "get": a word for reading.
    Description, as the server wrote it
    The URL of one part of a dataset as GeoJSON, plus its description. Fetch the URL for the features; parts can be several megabytes.

    • The name "get_layer" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "list_datasets" says "list": a word for reading.
    Description, as the server wrote it

    Why it is in this group

    • The name "list_hubs" says "list": a word for reading.
    Description, as the server wrote it
    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_layersMap layers this server can draw as GeoJSON, with unit, source, licence, whether it is available here, and how to read it.No findings

    Why it is in this group

    • The name "list_layers" says "list": a word for reading.
    Description, as the server wrote it
    Map layers this server can draw as GeoJSON, with unit, source, licence, whether it is available here, and how to read it.

    Why it is in this group

    • The name "list_places" says "list": a word for reading.
    Description, as the server wrote it
    Named places the fetchers read for, with their upstream ids (CO-OPS station, USGS gauge, eBird region) and tags.

    Why it is in this group

    • The name "search_sources" says "search": a word for reading.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
