This video is a three-dimensional (3D) view of Lake Powell topobathymetric digital elevation model, which consists of topography (land elevation) and bathymetry (water depth). The 3D topobathymetric model was developed by the U.S.

This video highlights two mosaics of the Jezero crater landing site on Mars made by the USGS Astrogeology Science Center to support the Mars 2020 mission, as well as several key locations that the Perseverance rover may visit once it is on the surface.

Mount Nyiragongo is a stratovolcano in the Democratic Republic of the Congo. It’s one of the most active in the world, having exhibited volcanic activity at least once every 3 months since May 17, 2002.
 

LCMAP Collection 1 includes 10 Science Products, offering different perspectives for the study of land change across the country, through time. The primary and secondary land cover products, provide important information on the most likely land cover class for each pixel. Their associated confidence products record the level of confidence in each classification.

The video describes work by Jay Wellik, a USGS seismologist and his colleagues with the Volcano Disaster Assistance Program (VDAP). They assisted Indonesia's CVGHM in responding to the 2017 activity/eruption at Mt. Agung, on the island of Bali.

Summer vacation plans changed for many in 2020. Whatever your plans, Landsat can take you on a virtual road trip. Landsat 8, in its sun-synchronous polar orbit, views every national park in the U.S. every 16 days and gathers more photographic data than the most ambitious of tourists.

 

This is an animation showing the changing conditions of USGS streamgages from April 1, 2020 to June 30, 2020. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding.

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, gives an overview of activity at Yellowstone during June 2020.

 

Multiple stressors such as climate change impacts and invasive species can have compounding impacts on native inland fish.

This thermal video shows typical activity at Kīlauea's summit water lake. Steam carried across the water surface often masks thermal features on the underlying water surface. USGS video by M. Patrick.

The video describes USGS efforts to improve lahar (mudflow) monitoring at Mount Rainier, an ice-clad volcano in Washington State with potential for dangerous volcanic mudflows. The presentation was given to colleagues in the US and in Ecuador by Andy Lockhart.

Reflections on the Ridgecrest earthquake sequence one year after from a few USGS employees. Employees discuss when they first heard about the magnitude 6.4 and notable professional experiences that happened afterwards.
 

This video describes USGS use of Unoccupied Aircraft Systems (UAS) or "drones" for use in 2018 at Kilauea Volcano in Hawaii. The speaker, Angie Diefenbach, is a leading expert in use of UAS for volcano surveillance and research. The presentation was given in June 2020 to colleagues in Ecuador who are interested in applications of UAS at their volcanoes.

In a remote part of the Sahara Desert in Egypt, center pivot irrigation fields fill the landscape. Thanks to the Landsat archive, we can see how dramatically this area has changed over the last 35 years. But until the growth in irrigation, this part of the world hadn't changed much from a satellite's perspective.

This video describes Step 2 of the Land Treatment Exploration Tool. In Step 2 the user defines their planned treatment boundary. The user can load a zipped shapefile or on-screen digitize their boundary.  

This video describes Step 3 of the Land Treatment Exploration Tool. In Step 3 the user is guided to the Site History tab to explore land treatment and wildfire history of their planned treatment area.

This video describes Step 5 of the Land Treatment Exploration Tool. In Step 5 the user determines a distance or boundary to search for legacy Land Treatment Digital Library records. The user also indicates if the returned LTDL treatments are statistically evaluated against the planned treatment boundary using a Bray-Curtis Dissimilarity calculation.

This video describes Step 6 of the Land Treatment Exploration Tool. In Step 6 the user filters through the returned list of legacy LTDL treatments to identify records that contain useful information or context for the current planned treatment boundary. Selected treatments are added to the developing report and subsequent exported Site Characterization PDFs.

This is a quick introduction video to the Land Treatment Exploration Tool. This short video includes a summary of the tool with screen clips of the fact sheet, web tool, and an example Site Characterization Report.

This video describes Step 4 and the developing report of the Land Treatment Exploration Tool. In Step 4 the used selects layers to generate spatial overlap statistics with their planned treatment boundary. Summary tables are generated and displayed in the Report tab, where a user can create a PDF Site Characterization Report for their planned treatment boundary.
