Today, these efforts are reflected in the sciences of NOAA's National Ocean Service and in the work of the National Institute of Standards and Technology, U.S. Department of Commerce., (Left Side Plaque): National Oceanic and Atmospheric Administration U.S. Department of Commerce. The National Oceanic and Atmospheric Administration (NOAA) of the U.S. Department of Commerce includes in its organization the National Ocean Service which has within its mission the work of the Coast and Geodetic Survey. Today, NOAA charts the nation's waterways, provides for the national spacial reference system for precise mapping and charting, and produces aeronautical charts for the nation's airways., (Right Side Plaque): U.S. Coast and Geodetic Survey National Ocean Service. The Geodetic Control Station Hassler was established by NOAA's Coast and Geodetic Survey to honor its first superintendent. The station, a bronze disk stamped Hassler 1993, is located in the granite post in the center of this park. It is one of approximately 1,000,000 stations throughout the United States which comprise the National Spatial Reference System. These stations form the basis for latitude, longitude, elevation, and gravity measurements in the United States. . This historical marker is in Silver Spring in Montgomery County Maryland
