Description: The FCC Rules define the term "antenna structure" to include "[T]he radiating and/or receive system, its supporting structures and any appurtenances mounted thereon." In practical terms, an antenna structure could be a free standing structure, built specifically to support antennas or act as an antenna, or it could be a structure mounted on some other man-made object (such as a building or bridge). If the structure is mounted on some other man-made object such as a building or bridge, the structure must be registered with the FCC, not the building or bridge.Objects such as buildings, observation towers, bridges, windmills, and water towers that do not have an antenna mounted on them are not antenna structures and should not be registered. Keep in mind that the FCC only has jurisdiction over antenna structures, and thus, other objects that do not house antennas are not required to be registered with the FCC -- regardless of their location or height.Antenna Structure Registration (ASR) - OverviewDocumentation and Data Dictionary provided by FCC:Intro to ASR database filesASR Table Data ElementsASR Data Field Definitions

Description: These data contain a national scale Submerged Lands Act (SLA) boundary line, Limit of "8(g) Zone," line and Continental Shelf Boundary. The SLA boundary defines the seaward limit of a state's submerged lands and the landward boundary of federally managed OCS lands. The Outer Continental Shelf Lands Act "8(g) Zone" lies between the Submerged Lands Act (SLA) boundary line and a line projected 3 nautical miles seaward of the SLA boundary line. Within this zone, oil and gas revenues are shared with the coastal state(s). The Continental Shelf Boundary defines the seaward limit of federally managed OCS lands. The line depicts the limit of U.S. jurisdiction for offshore mineral development.These data were created in the applicable NAD83 UTM or NAD27 UTM/SPCS Projection and re-projected to GCS WGS84 (EPSG 4326) for management in BOEM's enterprise GIS. However, this service in this collection has been published in WGS 1984 Web Mercator Auxiliary Sphere (EPSG 3857). Because GIS projection and topology functions can change or generalize coordinates, these data are NOT an OFFICIAL record for the exact boundaries. These data are to be used for Cartographic purposes only and should not be used to calculate area.

Description: This feature class/shapefile contains locations of Hospitals for 50 US states, Washington D.C., US territories of Puerto Rico, Guam, American Samoa, Northern Mariana Islands, Palau, and Virgin Islands. The dataset only includes hospital facilities based on data acquired from various state departments or federal sources which has been referenced in the SOURCE field. Hospital facilities which do not occur in these sources will be not present in the database. The source data was available in a variety of formats (pdfs, tables, webpages, etc.) which was cleaned and geocoded and then converted into a spatial database. The database does not contain nursing homes or health centers. Hospitals have been categorized into children, chronic disease, critical access, general acute care, long term care, military, psychiatric, rehabilitation, special, and women based on the range of the available values from the various sources after removing similarities.

Intercity and transit ferry terminals. 4. Light-rail transit stations. 5. Heavy-rail transit stations. 6. Passenger-rail stations on the national rail network served by intercity rail and/or commuter rail services. 7. Bikeshare stations belonging to bikeshare systems that are open to the general public, IT-automated, and station based (contain hubs to which users can grab and return a bike). The bikeshare stations only include those from the latest IPCD data collection in 2022. Please consult the latest bikeshare layer (https://doi.org/10.21949/1522020) for the most current information. The IPCD includes data elements describing the location of the above types of terminals as well as the availability of intercity, commuter, and transit rail; scheduled air service; intercity and transit bus; intercity and transit ferry services; and bikeshare availability. Transit bus service locations are not specifically included in the database. However, the status of transit bus as a connecting mode is included for each bikeshare facility in the database.

Description: "GCCA Warehouse is the third-party temperature-controlled warehousing industry’s association. Founded in 1891 as the American Warehousemen’s Association in 1891; to National Association of Refrigerated Warehouses independently in 1961; to International Association of Warehouses in 1972; and to Global Cold Chain Alliance in 2023 to present. The Association as we know it today, was originally established when conventional warehousemen took on the demands of storing perishable food and soon realized the increased challenge and complexity of operating temperature-controlled storage facilitiesToday, the GCCA Warehouse sector promotes best practices in the temperature-controlled warehousing and logistics industry through research, industry benchmarking, networking, and education. GCCA Warehouse also advocates for members in legislative and regulatory arenas. All active members of GCCA are also members and beneficiaries of the work of the Global Cold Chain Foundation."

Description: The Geospatial Multi-Agency Coordination Group, or GeoMAC, is an internet-based mapping tool originally designed for fire managers to access online maps of current fire locations and perimeters in the US. Perimeters are submitted to GeoMAC by field offices. The GeoMAC team attributes the perimeters using various sources, and then posts them on the GeoMAC website and to an HTTP site for downloading. This file contains all the latest fire perimeters that were processed by the GeoMAC team between 2000 and 2018. The projection is geographic and the datum is NAD83.
Description: Polygons showing USACE Civil Works District boundaries. This dataset was digitized from the NRCS Watershed Boundary Dataset (WBD). Where districts follow administrative boundaries, such as County and State lines, National Atlas and Census datasets were used. USACE District GIS POCs also submitted data to incorporate into this dataset. This dataset has been simplified +/- 30 feet to reduce file size and speed up drawing time. 05/05/20 - Update to show new LRC boundary. Minor change between LRL and LRH.
Description: Maritime limits for the United States are measured from the U.S. baseline, recognized as the low-water line along the coast as marked on NOAA's nautical charts in accordance with the articles of the Law of the Sea. The baseline and related maritime limits are reviewed and approved by the interagency U.S. Baseline Committee. The primary purpose of this dataset is to update the official depiction of these maritime limits and boundaries on NOAA's nautical charts. The Office of Coast Survey depicts on its nautical charts the territorial sea (12 nautical miles), contiguous zone (24nm), and exclusive economic zone (200nm, plus maritime boundaries with adjacent/opposite countries). U.S. maritime limits are ambulatory and subject to revision based on accretion or erosion of the charted low water line. To ensure you are up-to-date and for more information about U.S. Maritime Limits and Boundaries, see http://www.nauticalcharts.noaa.gov/csdl/mbound.htm.For the full FGDC metadata record, see http://www.ncddc.noaa.gov/approved_recs/nos_de/ocs/ocs/ocs/MB_ParentDataset.html.Coordinates for the US/Canada international boundary, on land and through the Great Lakes, are managed by the International Boundary Commission. These boundaries are included with this dataset for continuity.
