Who is the LP DAAC?

The LP DAAC operates as a partnership between the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) and is a component of NASA’s Earth Observing System Data and Information System (EOSDIS). Data specialists, system engineers, user service representatives, and outreach staff work together to support LP DAAC activities and distribute data to the remote sensing community.

The LP DAAC provides land data products that are vital contributors to the inter-disciplinary study of the integrated Earth system to the public remote sensing community.

Process:  Once satellite data are received, they must be processed into a usable form. Some data, such as those from the ASTER sensor onboard NASA’s Terra satellite, are received and processed here at the LP DAAC, while others are processed before arriving to the archive.

Archive:  The LP DAAC actively archives a variety of land remote sensing data products from sensors onboard NASA satellites. The archive currently totals more than 1 petabyte of data (more than 1,000 terabytes or 1,000,000 gigabytes!) and distributes data to over 30,000 global users.

Distribute:  All of the data products in the archive are distributed free of charge to the remote sensing community via data access tools maintained by the LP DAAC. Data products are also available through NASA’s Earthdata Search and the USGS EarthExplorer search and download clients. Additionally, the LP DAAC supports data tools and services, which allow users to tailor the data such as being able to change data projection, subset the data, and more.

When and where was the LP DAAC established?

Located just outside Sioux Falls, South Dakota, the LP DAAC is located in the USGS Earth Resources Observation and Science (EROS) Center. On August 28, 1990, NASA and USGS established EROS as a Distributed Active Archive Center, or DAAC. A 65,000 square-foot addition to the building was constructed to support this new role for EROS, and was dedicated on August 19, 1996.
