NOAA CO-OPS Benchmarks

Overview This feature service provides benchmark records from NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS). It captures the identifying, descriptive, and positional information used to document coastal benchmarks and their relationship to tidal datum and geodetic reference work. Layer Contents Benchmarks — A point layer of benchmark locations with station identifiers, benchmark names and designations, monument and setting details, condition information, establishment and agency references, vertical mark attributes, and links to related NOAA OPUS and Integrated Database resources. Geographic Coverage The service covers benchmark locations associated with NOAA CO-OPS stations across the United States and its coastal territories, with a global geographic extent supported by the service geometry. Use Cases Supporting tidal datum and coastal surveying workflows Locating and referencing NOAA benchmark monuments in the field Connecting benchmark records to NOAA geodetic and station documentation Reviewing benchmark condition, publication, and verification status Source and Reference Information The records are organized around NOAA CO-OPS benchmark documentation and related database resources, including OPUS and Integrated Database links where available.
