Measured tools (9)

• search_sources

  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.

  Parameters:

  • query — string — Words matched against name, id, coverage, topics and licence note.
  • topic — string — One topic, e.g. weather, water, fires, flights, energy.
  • license — string
  • fetchable — boolean — true: only sources this server can fetch now; false: only catalogued ones.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_source

  One catalogue entry in full.

  Parameters:

  • id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_hubs

  Projects and catalogues that collect sources (God's Eye View, World Monitor, the MCP Registry, Source Cooperative, ...), with how each relates to this one.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_places

  Named places the fetchers read for, with their upstream ids (CO-OPS station, USGS gauge, eBird region) and tags.

  Parameters:

  • tag — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_readings

  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.

  Parameters:

  • source (required) — string — A source id with a fetcher (search_sources with fetchable=true).
  • lat — number — Ad-hoc point latitude (with lng). For weather and WSI.
  • lng — number — Ad-hoc point longitude (with lat).
  • min — string — usgs-earthquakes only: all | 1.0 | 2.5 | 4.5 | significant.
  • tag — string — Catalogue places with this tag, e.g. waterfowl, ice-fishing.
  • bbox — string — noaa-nwps only: xmin,ymin,xmax,ymax in degrees (≤400 sq deg); default the Great Lakes basin.
  • usgs — string — USGS monitoring location id(s), e.g. USGS-04193500.
  • coops — string — NOAA CO-OPS station id(s), comma-separated, e.g. 9063085.
  • ebird — string — eBird region code(s), e.g. US-OH-095.
  • limit — number — 1-1000, default 100.
  • place — string — Comma-separated catalogue place ids (see list_places).
  • since — string — ISO date or datetime; only readings at or after it.
  • state — string — epa-echo only: two-letter US state, default OH.
  • metric — string — Only readings of this metric.
  • window — string — usgs-earthquakes only: hour | day | week.
  • elevated — boolean — usgs-volcanoes only: true keeps volcanoes above normal.
  • forecast — boolean — false drops modelled future values.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_datasets

  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").

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_dataset_part

  The URL of one part of a dataset as GeoJSON, plus its description. Fetch the URL for the features; parts can be several megabytes.

  Parameters:

  • id (required) — string
  • part (required) — string — Two-letter state, or "all" for single-part datasets.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_layers

  Map layers this server can draw as GeoJSON, with unit, source, licence, whether it is available here, and how to read it.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_layer

  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.

  Parameters:

  • id (required) — string
  • lat — number — Ad-hoc point latitude (with lng). For weather and WSI.
  • lng — number — Ad-hoc point longitude (with lat).
  • min — string
  • tag — string — Catalogue places with this tag, e.g. waterfowl, ice-fishing.
  • bbox — string
  • date — string — YYYY-MM-DD; default today (US Eastern).
  • fuel — string — power_plants: coal, oil/gas, nuclear, hydropower, wind, utility-scale solar, geothermal or bioenergy
  • usgs — string — USGS monitoring location id(s), e.g. USGS-04193500.
  • coops — string — NOAA CO-OPS station id(s), comma-separated, e.g. 9063085.
  • ebird — string — eBird region code(s), e.g. US-OH-095.
  • place — string — Comma-separated catalogue place ids (see list_places).
  • state — string
  • min_mw — number
  • status — string — power_plants: operating | construction
  • window — string
  • country — string — power_plants: ISO alpha-3, e.g. DEU
  • elevated — boolean
  • indicator — string
  • continuing — boolean — volcanoes_world: only eruptions in progress
  • erupted_since — number — volcanoes_world: year, default 1900
