USGS The National Map (TNM) Access API — the federal download catalog for national geospatial data: 3DEP elevation (DEMs and lidar point clouds), US Topo and Historical Topo quadrangles, NHD hydrography, NLCD land cover, National Structures, Transportation and Boundaries. Every product record carries a direct download URL, format, footprint and publication date.

Tools

• tnm_datasets(filter?) — the dataset catalog with each dataset’s exact title, refresh cycle and formats. Call first.
• tnm_search_products(datasets?, bbox?, polygon?, prod_formats?, prod_extents?, q?, date_type?, start_date?, end_date?, limit?, offset?) — search downloadable products.
• tnm_products_at_point(latitude, longitude, datasets?, prod_formats?, buffer_degrees?, limit?) — which products cover a single coordinate.

Data sources

• https://tnmaccess.nationalmap.gov/api/v1/datasets — dataset catalog.
• https://tnmaccess.nationalmap.gov/api/v1/products — product search.

Traps

• datasets takes the dataset’s full title, not its id, and a title the API does not recognise is ignored rather than rejected — you get an unfiltered result set that looks like a successful narrow search. Resolve the exact string with tnm_datasets first.
• bbox is xmin,ymin,xmax,ymax in WGS84 decimal degrees, longitude first. A reversed box returns zero items with a 200; this pack refuses one rather than passing it through.
• The response’s total is the real match count and items is one page. A short array with a large total means “page it”, not “that is all”.

Tools

• tnm_datasets — List the USGS National Map dataset catalog — 3DEP elevation (DEM and lidar point cloud), US Topo and Historical Topo quadrangle maps, NHD hydrography, NLCD land cover, National Structures, Transportat
• tnm_search_products — Searches USGS The National Map for downloadable elevation, lidar, topo and land-cover products, each with a direct download URL.
• tnm_products_at_point — Find every USGS National Map product covering a single latitude/longitude — which elevation tile, lidar project, topo quadrangle or land-cover raster contains this spot — each with its direct download
