With rapidly rising sea levels and drastically declining river discharge, the Changjiang Delta, near Shanghai, China, is continually evolving. Using Landsat imagery, researchers focused on tidal level fluctuations to help understand the changes to the largest uninhabited island in the estuary, Jiuduansha island.

The 22nd William T. Pecora Memorial Remote Sensing Symposium (Pecora 22) convenes in Denver, Colorado from October 23 – 28, 2022.

Landsat Updates are prepared periodically and distributed electronically to provide information about Landsat activities and related topics of interest.

The South American Savannas host several species, including ocelots and nutria rats. The soil is rich soil results in plantations of bananas, coffee, and other crops. Areas are cleared out for the fertile humus. The tropical Brazilian Cerrado is the largest savanna on the continent and the most threated biome from agricultural expansion.

This map of the Cape Cod region is created with the National Land Cover Dataset (NLCD). The dataset classifies land cover into categories such as developed areas, forests, wetlands, and water bodies, providing a detailed view of the region's composition.

The Operational Land Imager (OLI) onboard Landsat 8 captured this image of Lake Tahoe.

The Betsiboka River in Northern Madagascar is seen in this Landsat 9 natural color image from December 7, 2021. Extensive logging has left the land vulnerable, and iron rich soils are washed into the river, coloring it a reddish orange as it flows to the Betsiboka estuary delta.

Deforestation can happen naturally, through infestation of native beetles and extreme weather. However, people can intentionally clear forests for timber and other industries. Difference between the two can be difficult to diagnose.

On Tuesday December 7, 2021, updates were made to all USGS webpages, including the Landsat Missions Web Site (LMWS).

On November 23, 2021, the Landsat Archive added its ten millionth image. The Landsat 7 scene was acquired over the Dead Sea and is shown as a false color image using the short-wave infrared, near infrared and red bands (bands 5,4,3).

These images of an area in south central Queensland, Australia were acquired by the instruments onboard both Landsat 8 and Landsat 9 on November 15, 2021, as Landsat 9 flew beneath Landsat 8 as the satellite continued its climb to nominal orbital altitude.

Sediments swirl in Lake Erie and Lake St. Clair in this Landsat 9 image of both Detroit, Michigan, and Windsor, Ontario, from Oct. 31, 2021. The Great Lakes serve as sources of freshwater, recreational activity, transport, and habitat for the upper-midwestern US, and water quality remains a high priority. 

The city of Kathmandu, Nepal, seen at the bottom left of this Landsat 9 image, lies in a valley south of the Himalayan Mountainsbetween Nepal and China. Glaciers, and the lakes formed by glacial meltwater, are visible in the top middle of this image.

In the Western U.S., in places like the Navajo Nation as seen in this Landsat 9 image, Landsat and other satellite data help people monitor drought conditions and manage irrigation water. With only 85 rain gauges to cover more than 27,000 square miles, satellite data and climate models are filling the gaps to help the Navajo Nation monitor drought severity.
