Forest Service

aid: forest-service
name: Forest Service
description: 'The U.S. Forest Service is an agency of the U.S. Department of Agriculture managing 193 million acres of national
  forests and grasslands. Not a software vendor, it nonetheless runs four free, entirely unauthenticated public HTTP APIs:
  the FIADB-API behind EVALIDator, returning Forest Inventory and Analysis population estimates with sampling errors from
  the nation''s continuous forest census; the Research Data Archive web service, a search-and-retrieve API over DOI-registered
  research datasets that also runs an OAI-PMH 2.0 repository serving Dublin Core and FGDC metadata; and two FSGeodata ArcGIS
  REST servers publishing the Enterprise and Research Data Warehouse map services, 144 in the EDW folder alone, each also
  exposing a SOAP contract. A DCAT-US 1.1 open-data catalog is published through Geospatial Data Discovery. No API needs a
  key or an account, every operation is a read, and the data are works of the U.S. government.'

  name: FIADB-API (EVALIDator)
  description: The Forest Inventory and Analysis Database API, the machine surface behind the EVALIDator web application.
    A single GET or POST to /fullreport returns population estimates with standard errors, variances and plot counts, grouped
    by row, column and optional page attributes, for one or more state/year evaluations. Every classed parameter has a live
    value dictionary at /fullreport/parameters/<name>. Free, anonymous, CORS-open, and documented with worked Python and R
    examples.

  name: Forest Service Research Data Archive Web Service
  description: Search and retrieve DOI-registered Forest Service research data publications. Four REST endpoints — /search,
    /product, /organizations and /efrs — plus a full OAI-PMH 2.0 repository at /oaipmh serving Dublin Core (oai_dc) and FGDC-STD-001.1-1999
    (fgdc) metadata. The two lookup endpoints exist so a client can discover the legal values for the funder and experimental-forest
    filters. XML by default, JSON on request. Dated release notes run from 2014 to 2019 and the service is still answering.

  name: FSGeodata Enterprise Data Warehouse Map Services
  description: The Forest Service enterprise ArcGIS REST server. A self-describing services directory (currentVersion 11.5)
    across nine folders — EDW, RDW_AdminAndOwnership, RDW_Climate, RDW_FIA_ForestAtlas, RDW_InventoryAndProducts, RDW_LandscapeAndWildlife,
    RDW_Wildfire, Utilities and wo_nrm_iweb — with 144 MapServer services in the EDW folder alone covering surface ownership,
    forest system boundaries, activity records, aerial fire retardant avoidance areas, aquatic organism passage and Bailey's
    ecoregions. Each service document links the dataset's FGDC metadata XML, and each service also publishes a WSDL 1.1 SOAP
    contract with 55 operations. OGC WMS/WFS is not enabled.

    plus hosted feature services. Same anonymous ArcGIS REST contract and same ?wsdl SOAP surface as the enterprise server.

  description: 'The agency''s Geospatial Data Discovery site publishes a machine-readable DCAT-US 1.1 / Project Open Data
    catalog of Forest Service datasets — a ~2 MB JSON document declaring "@type": "dcat:Catalog" and conformsTo the Project
    Open Data v1.1 schema, with a dataset[] array of dcat:Dataset entries. This is the inventory federal agencies publish
    under the OPEN Government Data Act. The site is named as an official access route on the agency''s own FSGeodata Clearinghouse
    Map Services page, which is how the Esri-tenant hostname is confirmed as a Forest Service surface rather than a vendor''s.'
