Latest in Landsat - October 2023 - Vol. 2 | Issue 10
In September, a new paper describing Landsat Collection 2 was published, a webinar was held to promote Landsat products and services, and updates were made to the Atmospheric Auxiliary data that are used in the processing of Landsat Level-2 products. Check these and other stories out below!
New Paper Promotes the 50-year Landsat Collection 2 Archive
Recognizing the need for consistently processed remotely sensed data, the USGS initiated collections-based processing to ensure superior radiometric and geometric quality through time and across all Landsat instruments. In 2016, the entire Level-1 data archive were processed as Collection 1. In preparation for Landsat 9, the USGS archive was reprocessed as Collection 2 in 2020.
Using the Power of Landsat and Digital Earth Tools to Understand Coastlines in Australia and Africa
How leading-edge Landsat based Earth observation products and tools are helping us to understand Africa’s and Australia’s coastlines. This is the first in a series of four articles showcasing the socio-economic benefits of Digital Earth Africa and Australia products and services, through user case studies and impact stories.
Atmospheric Auxiliary Data Changes Affect Landsat 8-9 Level 2 Surface Reflectance Processing
Landsat Collection 2 Level 2 product processing requires auxiliary atmospheric characterization data from multiple external sources. Landsat 8 and Landsat 9 surface reflectance data acquired on October 1, 2023, and onward will utilize a different source of atmospheric characterization data than what has been used previously.

Landsat Science Team Meeting Presentations Search
During Landsat Science Team meetings, members present their research that is relevant to the meeting topics, and are briefed by USGS and NASA staff on mission and program status. The Landsat Science Team Meeting Presentations search tool enables the search and discovery of all presentation presented at previous meetings.
EROS 50th History: Landsat Unites USGS and NASA
Inspired by early images of the Earth from space, the Department of the Interior and the USGS had a bold idea in the 1960s to launch a satellite to keep a constant eye on Earth. But they needed NASA’s help to pull it off.
EROS 50th History: Responding to Disasters
Landsat satellites captured vivid imagery of the massive fires blazing across Canada earlier this year: orange flames, ugly burn scars, thick smoke.
The U.S. Geological Survey’s Earth Resources Observation and Science (EROS) Center was ready to share relevant images and data as quickly as possible to agencies responding to the fires.
