Why does the GEDI orbit footprint look the way it does? GEDI produces high resolution laser ranging observations of the Earth's forests and topography. GEDI was deployed to the International Space Station in 2018, and captures data along the ISS orbit shown here. When viewed in two dimensions, the ISS orbit resembles a net of offset waves This animation shows a full GEDI

London Bridge was indeed falling down. Set to be torn apart and replaced in the 1960s, this bridge across the River Thames was purchased by businessman Robert McCulloch in April 1968 and shipped across the Atlantic, to Lake Havasu City, Arizona, billed as the world's largest antique. USGS aerial photos show the location in 1969, and in 1972, before and after the bridge's

The U.S. has plenty of data on wildfire risk. There are local and regional risk assessments, complex datasets like LANDFIRE and tracking tools like the EROS Fire Danger Monitor, as well as a host of resources and research projects devoted to the subject. But much of that information is steeped in the language of fire science and difficult to comprehend for those outside it

The Staten Island Industrial Park in New York is now home to warehouse and distribution centers for companies like Amazon and IKEA, seen here in imagery from Europe's Copernicus Sentinel-2 satellite. But aerial imagery from 1995 shows large oil storage tanks in the same location. The observed changes in this industrial zone highlight an interesting evolution from an

In the West African nation of Ghana, tropical forests are more than landscape. They are woven into language, custom, and culture. They are also the source of timber for home heating and industry, as well as barriers to agricultural production. Those are just a few of the reasons why deforestation has come alongside the nation’s rapid population growth. In this episode of

The Mendenhall Program offers a range of two-year post-doctoral research fellowships within the U.S. Geological Survey. Heather Tollerud took advantage of the program in 2015 to study drought and land cover at the USGS EROS Center, and has since become a key player in the Center’s innovative Land Change Monitoring, Assessment and Projection (LCMAP) initiative. In this

The study of the Earth's natural life cycles is known as phenology. Scientists track the emergence of shoots and leaves, blooming flowers and pollinators as phenological signals every spring. Spring has sprung earlier than usual in much of the United States this year. The USA National Phenology Network notes that much of the country has seen spring come 3 to 4 weeks faster

Antarctica has been the source for a host of fascinating satellite imagery in recent months. We've offered scenes from the southern solstice, images of icebergs adrift, and shots of pooling meltwater during some of the warmest days on record for the frozen continent. An international team of scientists onboard a U.S. research vessel recently made another discovery related

This Landsat 8 image from May 24th, 2017 shows an enthralling New Zealand landscape. Snow-capped mountain peaks, forests, farmland, and fog highlight the picturesque view of New Zealand's North Island. The scene was downloaded on March 9th, 2020 one of over 29,000 Landsat scenes downloaded worldwide that day. But this scene is special. It marks the 100 millionth downloaded

Landsat recently captured the most widespread meltwater pooling ever recorded on Antarctica's George VI Ice Shelf. Some melting is expected during the Antarctic summer, but the sheer extent of the stunning aqua ponds that have appeared amid the continent's warmest summer on record is remarkable.

Ponds appeared two years earlier in some of the same locations

For decades, each Landsat image had a price tag – a hefty one at times, ranging from $400 to as much as $4,000. That all changed in 2008 with the enactment of an open data policy that made the entire Landsat archive available for download at no cost to the user. In this episode of Eyes on Earth, we talk with one of the architects of that policy, as well as an EROS data
