The LP DAAC recently released a new website designed to help you find the right data for your project. This video walks through 3 search options. https://lpdaac.usgs.gov

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, gives an overview of activity at Yellowstone during 2019, with an emphasis on the month of December.

This timelapse sequence shows two hours of activity at the water pond in Halema‘uma‘u, at Kīlauea's summit. Flow is evident along the sharp orange color boundary in the center of the pond, as well as along portions of the shoreline. The pond is 189 m (650 ft) long. The vido was taken on the eastern rim.

An overflight on December 18 provided aerial photographs of Kīlauea caldera, which were used to construct a 3D model. The water pond is visible in the deepest portion of Halema‘uma‘u crater. For scale, the water pond is 189 m (650 ft) long and approximately 600 m (1970 ft) below the western caldera rim.

The smell of a fresh cut Christmas tree can evoke visions of majestic evergreen forests teeming with winter wildlife. In truth, more than half of U.S. Christmas trees come from farms in Oregon, North Carolina, or Michigan. Cut Christmas Trees area commodity, tracked by the U.S. Department of Agriculture just like corn or soybeans. These USDA aerial images show tree harvest

By the end of this lesson, you will be able to load multiple LAS files, define and use a polygon area of interest to subset LAS files, and generate and export raster surfaces and contours derived from the LiDAR point cloud. If necessary, please review Lesson 10c1 for guidance with importing LAS files, filtering, and visualizing LiDAR point clouds in Global Mapper.
 

Fires burned across California in late 2019. Fall is the state's most dangerous season for wildfires, propelled by dry and windy conditions. In recent years however, the fall fire season has been starting earlier and ending later. A series of images from the MODIS sensor on NASA's Terra and Aqua satellites show the Kincade Fire in northern California. This fire started on

The USGS has developed Landsat-derived Level 2 and Level 3 science products that reduce the amount of time users spend on data processing and provide research quality, applications-ready information to monitor, assess and project how changes in the Earth's surface may affect communities and ecosystems. The Landsat Program is a series of Earth-observing satellites co-

The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards during storms. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision-making. Here we

Low-lying island environments are particularly vulnerable to impacts from coastal hazards, including inundation (coastal flooding), whether the increased water levels are from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long term sea-level rise). Elevation is the primary geophysical variable that determines exposure to inundation in

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone during the month of November 2019.

USGS Hawaiian Volcano Observatory scientists Frank Younger and Patricia Nadeau talk about sampling the water at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano. The water appeared in July 2019 and has steadily risen since then. On October 26, 2019, an unoccupied aerial system (UAS) was used to collect a sample of the water to investigate its source

Title: Sea-Level Rise, Extreme Water Levels, and Coastal Erosion ... How bad could it possibly be?

• Sea-level rise represents an unprecedented civil engineering challenge.
• Small amounts of sea-level rise can disproportionately increase the frequency of coastal flooding.
• One-third to two-thirds of the beaches in Southern California may disappear

The U.S. Fish and Wildlife Service’s (FWS) Everglades Headwaters National Wildlife Refuge (EHNWR) is strategically located in Florida to protect upland and wetland habitats. The location of the new refuge was targeted to: address pressures from urbanization and climate change, provide improved quality of water flowing southward to the Greater Everglades, and protect

Wildfires burned across Lebanon in mid-October, 2019. A pair of images taken just ten days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires. North of the fire scar is the country's capital, Beirut. The October 18th image reveals several bright spots on the city's streets from numerous fires of a different type.

In this video, you can hear the honks and quacks of geese and ducks ring through the air, as birds fly in every direction above a wetland. This video was captured at Sacramento National Wildlife Refuge in November 2019, not long after geese and ducks began to arrive to spend the winter in the California Central Valley.

This lesson will cover additional LiDAR point cloud processing and analysis features in Global Mapper.
