generated: '2026-09-05' method: derived source: >- derived from the live ArcGIS REST service and layer documents at https://gis.boem.gov/server/rest/services (probed 2026-09-05) and the eleven OGC GetCapabilities documents saved verbatim in openapi/ note: | There is no $ref graph to walk here — BOEM's contract is OGC/Esri, not OpenAPI, so the entity model is the LAYER SET, and the relationships are spatial and cadastral rather than foreign-key. What follows is the real, enumerated layer inventory of the six public map services, plus the shared entities that recur across regions. The organising fact: BOEM publishes ONE conceptual model replicated across five OCS regions (Alaska, Atlantic, Gulf of America, Pacific, and the Marine Minerals composite). Seven entities appear in every region — wells, platforms, pipelines, the OCSLA 8(g) limit, the Submerged Lands Act boundary, protraction diagrams, lease blocks, leases and planning areas. A consumer that models one region models them all; only the region prefix changes. Layer ids are NOT contiguous and are NOT portable across services. 'BOEM Oil and Gas Leases' is id 6 in AK_Layers, id 7 in GOA_Layers and POC_Layers, and id 15 in MMC_Layers — and does not exist at all in ATL_Layers. Address layers by name resolved from the MapServer document, never by a hard-coded id. identifiers: primary_key: OBJECTID (esriFieldTypeOID) on every feature layer geometry_field: SHAPE note: >- OBJECTID is an Esri row id, stable only within one layer of one service. It is not a BOEM business identifier. The real cadastral keys are BLOCK_NUMBER, protraction and lease identifiers carried as string attributes. example_schema: layer: BOEM_BSEE/ATL_Layers/MapServer/0 (BOEM Limit of OCSLA 8(g) zone) fields: -
