The International Real-time Magnetic Observatory Network (INTERMAGNET) is a world-wide consortium of institutes operating ground-based magnetometers recording the absolute level of the Earth's time-varying magnetic field, [2] [3] [4] to an agreed set of standards. INTERMAGNET has its roots in discussions held at the Workshop on Magnetic ...
A USGS gauging station on the Scioto River below O'Shaughnessy Dam near Dublin, Ohio. The USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data [17] are available online.
The data was entered in spreadsheet format or in ESRI shapefiles and submitted via e-mail to the USGS National Geospatial Technical Operations Center(s) in Denver, Colorado, and Rolla, Missouri. During the registration process, prospective volunteers submitted a list of the 7.5 minute quadrangle maps on which they wished to work.
The National Elevation Dataset (NED) consists of high precision topography or ground surface elevation data (digital elevation model) for the United States. It was maintained by the USGS and all the data is in the public domain. Since the 3D Elevation Program came online, the NED was subsumed [1] into The National Map as one of its layers of ...
Climate web viewer containing accessible climatic information from 1901 that can be downloaded in a variety of GIS formats. HydroSHEDS: Global hydrological data based on the SRTM elevation data. Includes river networks, watershed boundaries, drainage directions, and flow accumulations. USGS Land Cover Institute
The inventory is updated semi-annually. Note, however, that getting access to the data is often less than straightforward in the current implementation. History: In the United States, the United States Geological Survey (USGS) was the lead agency coordinating efforts across multiple agencies towards a National LIDAR Dataset. The first meeting ...
According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
The volcano has remained relatively active since the 1996 swarm and is monitored by the United States Geological Survey (USGS). The Hawaii Undersea Geological Observatory (HUGO) provided real-time data on Kamaʻehuakanaloa between 1997 and 1998. Kamaʻehuakanaloa's last known eruption was in 1996, before the earthquake swarm of that summer.
