The LP DAAC processes, archives, and distributes land data products to hundreds of thousands of users in the earth science community. Our land data products are made universally accessible and support the ongoing monitoring of Earth’s land dynamics and environmental systems to facilitate interdisciplinary research, education, and decision-making.
Process: Raw data collected from specific satellite sensors, such as ASTER onboard NASA’s Terra satellite, are received and processed into a readable and interpretable format here at the LP DAAC, while other data undergo processing in other facilities around the country before arriving to the LP DAAC to be archived and distributed to the public.
Archive: The LP DAAC continually archives a wide variety of land remote sensing data products collected by sensors onboard satellites, aircraft, and the International Space Station (ISS). The archive currently totals more than 3.5 petabytes of data, the equivalent of listening to 800 million songs, and distributes data to over 200,000 global users.
Distribute: All data products in the archive are distributed free of charge through NASA Earthdata Search and USGS EarthExplorer search and download clients. The LP DAAC supports tools and services, like the Application for Extracting and Exploring Analysis Ready Samples (AppEEARS), which allows users to transform and visualize data before download while offering enhanced subsetting and reprojecting capabilities.
Apply: Visit our Data in Action and Publications Table to learn about how LP DAAC data products have been utilized in various studies and applications of diverse disciplines; browse through our media wall to see pretty pictures of our data that you can share with friends and colleagues; interact with the land data science community on the Land Data Forum; and discover a suite of Tools and E-learning materials available to support a variety of research needs.
The LP DAAC is located just outside of Sioux Falls, South Dakota at 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.
Our diverse community of users includes scientists, researchers; federal, state, and local government, educational and commercial professionals, application users, and the general public.
The LP DAAC archives and makes data accessible through the NASA Earth Science Data Systems Program that are relevant to understanding Earth’s land dynamics and environmental systems.
New products can be submitted through the LP DAAC 产品介绍 Submission Form.
