Remote sensing is a powerful tool to measure fire’s effects on plant life. How severe was the damage to vegetation? How quickly can a landscape recover? A new project is looking at those questions from a before, during, and after fire perspective, and the Wildland Fire Team at EROS investigates how using different remote sensing ...

In collaboration with the US Geological Survey (USGS), we recently updated Esri’s online USGS historical topographic map collection with over 1,745 new maps, bringing the total number of maps in our collection to over 181,000 (181,008 to be exact). We also corrected a number of maps that our users reported as having georeferencing or other ...

Nearly 75% of the U.S. could experience damaging earthquake shaking, according to a recent U.S. Geological Survey-led team of more than 50 scientists and engineers. This was one of several key findings from the latest USGS National Seismic Hazard Model (NSHM). The model was used to create a color-coded map that pinpoints where damaging earthquakes ...

The U.S. Geological Survey recently published a new topobathymetric lidar dataset for the Potomac River as part of its 3D Elevation Program (3DEP). Topobathymetric lidar provides 3D maps of the submerged riverine topography. The maps were produced in two phases for more than 120 river miles of the Potomac River through a data-acquisition contract with ...

The U.S. Geological Survey (USGS) has released a compilation of national-scale geological, geophysical and mineral resource datasets from Australia, Canada and the US through a collaboration between the three countries’ federal geological surveys. “Geology doesn’t stop at the border and neither does our data,” said USGS scientist Anne McCafferty, who led the effort. “Scientists will ...

El Instituto Nacional De Estadística Y Geografía (INEGI) Pone A Disposición De Las Y Los Usuarios El Índice De Clasificaciones De Agua Superficial Desde El Espacio (ICASE) Landsat 2022. Este Consiste En Un Producto De Análisis Geoespacial Experimental Que Proporciona Información Sobre La Presencia De Agua Superficial A Lo Largo De Todo El Territorio Mexicano. ...

Scientists routinely rely on data-intensive analysis and visualization of satellite observations to track Earth’s ever-changing surface. A new project will make it possible for anyone with an internet connection to begin to answer these questions and more about changes to our dynamic planet. The OPERA (Observational Products for End-Users from Remote Sensing Analysis) project is ...

Mauna Loa volcano began erupting in Moku‘āweoweo Caldera on November 27, 2022. A long-feared Mauna Loa eruption has now disrupted several flights and triggered in an all-hands emergency response. As of now there are no mandatory evacuations in place, but shelters have opened to accommodate those opting to leave voluntarily. The eruption comes after months ...

From Lake Pontchartrain to the Texas border, Louisiana has lost enough wetlands since the mid-1950s to cover the entire state of Rhode Island. Using a first-of-its kind model, NASA-funded researchers quantified those wetlands losses at nearly 21 square miles (54 square kilometers) per year since the early 1980s. In the new study, scientists used the ...

NASA and the U.S. Geological Survey (USGS) will map portions of the southwest United States for critical minerals using advanced airborne imaging. Hyperspectral data from hundreds of wavelengths of reflected light can provide new information about Earth’s surface and atmosphere to help scientists understand Earth’s geology and biology, as well as the effects of climate ...

NASA transferred ownership and operational control on Thursday of the Landsat 9 satellite to the U.S. Geological Survey (USGS) in a ceremony in Sioux Falls, South Dakota. Landsat 9 is the most recent in the Landsat series of remote-sensing satellites, which provide global coverage of landscape changes on Earth. The Landsat program – a joint ...

In June, days of heavy rains and snowmelt led to the flooding of Yellowstone River and rivers in other parts of Montana, Wyoming and Idaho, causing what the U.S. Geological Survey referred to as a “1 in 500-year event.” The flooding destroyed bridges, swept away roads, spurred mudslides, led to the evacuation of more than ...
