The largest coral reef ecosystem in the world, the Great Barrier Reef (GBR), is threatened by many human-made impacts. Due to the size of the GBR and limited accessibility, mapping and monitoring has always been a challenging task. Remote Sensing is an effective technique that provides valuable information for the GBR ecosystem.

The boreal forest biome is projected to shift northward due to continued climate change over the coming century. Researchers evaluated early indicators of a boreal forest biome shift using four decades of Landsat observation datasets.

Landsat 9 captured this natural color image of the ongoing fire in Uljin county on South Korea’s west coast.

Landsat 9 captured an image of the ongoing fire in Uljin county on South Korea’s west coast. The false color image looks beneath the smoke and shows the burn scar as reddish-brown and the heat signature from the fire as bright red.

The Landsat Science Team met virtually on February 9, 2022. Topics included, but were not limited to, Landsat 9 operations, calibration, and data release plans; Landsat 7 mission status; Landsat and Sentinel harmonization; and the future of land imaging.

This Landsat 9 image shows a portion of the Otago Harbor area that is situated on the southeastern coastline of New Zealand's South Island. 

The city of Dunedin can be seen at the the head of the harbor. 

This image was acquired March 2, 2022.

Rangeland management has used Landsat imagery for 50 years. Satellite imagery can provide a more comprehensive view of native pastures and prairies that cover swaths of Western America.



A new paper in Elsevier provides four guiding principles for ranges:

1. Use maps within a decision-making framework

Landscape ecologists are increasingly researching change processes with regards to spatial patterns.

The Geba River on the west coast of Guinea-Bissau is seen in this natural color Landsat 9 image from February 8, 2022. Silt carried by the river into the Atlantic Ocean creates intricate patterns as it moves around the Bissagos (or Bijagós) Islands. The country’s capital, Bissau, can be seen on the north side of the estuary and appears as light brown.

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 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.

In the International Polar Year 2007-2008, Landsat 7 brought the coldest continent to life with high resolution satellite imagery.

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.

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.
