BTS Geospatial Search API (NTAD)

The search and catalog API behind Geospatial at the Bureau of Transportation Statistics, the home of the National Transportation Atlas Database (NTAD). It is a conformant OGC API - Records implementation: the landing page at /api/search/v1 advertises a conformance document declaring nine opengis.net classes across OGC API - Common Parts 1 and 2, OGC API - Features Part 1 and OGC API - Records Part 1, and a service-desc link to a first-party OpenAPI 3.0 definition with 17 operations. Catalog records resolve to 1,079 live ArcGIS FeatureServer layers plus GeoJSON, CSV, Shapefile, KML and GeoPackage downloads. Anonymous, free, read-only.

Where this information came from

This is an independent, third-party profile of BTS Geospatial Search API (NTAD), published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
