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. The work describes use of software to characterize the different types of earthquakes at the volcano, and how that revealed

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. While we do see floods in this animation, we also see a number of low

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

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. Andy is a geophysicist with the the USGS/USAID Volcano Disaster Assistance Program, and he has worked to reduce

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. Angie is a member

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.
 

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. That's why Landsat calibration engineers originally chose it

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.  

These

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 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. Optionally

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. They are also directed to the Fish and Wildfire Information for Planning and Consultation tool to investigate areas of overlap with endangered species, migratory birds, and

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 1 of the Land Treatment Exploration Tool. In Step 1 the user defines a name, the planned treatment/s, and a file name for exported items.

These tutorial videos were created to aid in the use of the Land Treatment Exploration Tool (LTET). These videos guide a user through the main steps of the tool.

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.

The Landsat series of Earth-observing satellites has been continuously acquiring land surface imagery since 1972. Over 8.5 million Landsat scenes are currently available for download. Soon it will all be accessible from a cloud environment, in a cloud optimized format that gives you more flexible, customized access. In the past, users could spend 80% of their time

The “LP DAAC Prospectus: 2019 to 2021” short video features the National Aeronautics and Space Administration’s (NASA) Land Processes Distributed Active Archive Center (LP DAAC), a key access point for global land remote sensing data. The video provides an overview of the significance of the DAAC’s archive and distribution functions, explains the depth of the user

This wide-angle video was captured during a helicopter overflight on May 29, and skirts the southern border of Halema‘uma‘u crater. The water lake, filling the bottom of the crater, was tan and brown today, and showed no significant changes. USGS video by M. Patrick.

A helicopter overflight provided aerial photographs of Kīlauea caldera on May 29, and these photos were used to construct a 3D model. The water lake is visible as the tan area in the deepest portion of Halema‘uma‘u crater. For scale, the water lake is 270 m (885 ft) long and approximately 600 m (1970 ft) below the western caldera rim. USGS photos by K. Mulliken.

Do you have what it takes to be a bat biologist? USGS bat researchers are counting Townsend’s big eared bats to monitor how their populations are doing. Watch the video to try your hand at a bat count and see how your skills compare to a USGS scientist! You don’t need sound to count the bats—but if you turn your sound on you’ll be able to hear the bats’ echolocation calls
