  title: Landgate SLIP Public OGC Web Services (WMS / ) WFS API
  version: '1.0'
  summary: OpenAPI description of the anonymously callable OGC WMS 1.3.0 and WFS 2.0.0 endpoints fronting Landgate's SLIP public data.
  description: 'Landgate publishes no OpenAPI. This is an API Evangelist GENERATED OpenAPI description of

    the OGC web services that the SLIP public host answers anonymously. The authoritative

    machine-readable contract for these services remains the OGC GetCapabilities documents,

    which are saved verbatim in this repo as

    `openapi/landgate-slip-public-wms-capabilities.xml` (WMS 1.3.0, 56 layers) and

    `openapi/landgate-slip-public-wfs-capabilities.xml` (WFS 2.0.0, 38 feature types).


    OGC services multiplex every operation onto one endpoint via the `request` query

    parameter, so this document models one operation per service endpoint with `request`

    as an enum, rather than inventing paths the server does not have.


    All operations were probed live on 2026-07-26 and returned HTTP 200 anonymously

    (see `x-evidence`). Note that WFS lives on the `*_WFS` map services: a WFS

    GetCapabilities against the plain `Boundaries` service returns HTTP 400.
