Landsat Update - Volume 6 Special Update 2012

Updates to Landsat Product Metadata

Actual Release Date: August 29, 2012.

In preparation for the launch of LDCM, the USGS has aligned all existing Landsat product metadata, from Landsat 1 through Landsat 7.

A planned release on August 21, 2012 will bring forth changes to the existing metadata files; some fields are changing, although much of the information has been retained. Between all sensors, there are many unique fields that apply to only one or one type, of data. All fields that are common between sensors now have matching fields. We believe this will make easier the searching and analyzing of scenes across the entire Landsat archive.

Most users will not be affected by this change. However, any automated scripts using the metadata will be affected by these changes.

Examples of current and new metadata files are available to download and review.

Both old and new files will be distributed with each Landsat scene for a minimum of three months to ensure that users have time to make the transition.

If you have questions or concerns, please contact the Landsat Customer Service team at custserv@usgs.gov.

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
