Steps

  1. Note the service's layer structure: 0=State Boundaries, 1=PLSS Township, 2=PLSS Section, 3=PLSS Intersected at gis.blm.gov/arcgis/rest/services/Cadastral/BLM_Natl_PLSS_CadNSDI/MapServer
  2. Query the Township layer by point: GET .../1/query?geometry=<lon>,<lat>&geometryType=esriGeometryPoint&inSR=4326&outFields=*&f=json to get the enclosing township/range polygon and PLSSID
  3. Query the Section layer (layer 2) the same way to get the specific section number, or filter by attribute if you already have the township ID
  4. Cross-reference results with the BLM Pathfinder application (glorecords.pathfinder.blm.gov) for the authoritative legal land description and survey plat images
  5. Note the service's max record count (2000) and default spatial reference (Web Mercator 3857), reprojecting output to your working CRS
