Data Citation and Policies

Learn how to properly cite data, tools, imagery, and other information obtained from the LP DAAC.

Data Access

All data products distributed by NASA's Land Processes Distributed Active Archive Center (LP DAAC) are available at no charge.

Data Redistribution

All LP DAAC data and products acquired through the LP DAAC, with the exception of ASTER GDEM Version 2, have no restrictions on reuse, sale, or redistribution.

Before ordering ASTER GDEM Version 2 (ASTGTM V002) data users must agree to only redistribute data products to individuals within their organization or project of intended use, or in response to disasters in support of the GEO Disaster Theme.

Data and Data Tool Citation

The LP DAAC would appreciate receiving an electronic copy of your publication via DOI link and hearing about your work using data and tools from our website. Please feel free to contact us to tell us about your research. Your input will help us stay informed about data use and may be highlighted as a use case of the data.

The LP DAAC requests that any author using NASA data products in their work provide credit for the data, and any assistance provided by the LP DAAC, in the data section of the paper, the acknowledgement section, and/or as a reference. The recommended citation for each data product is available on its Digital Object Identifier (DOI) Landing page, which can be accessed through the Search Data Catalog interface.

Tools that have recommended citations are provided on the individual tool page that can be found on the Tools Landing page. Note: AppEEARS will also include a pre-filled out citation in the email that is sent to you upon completion of processing.

If you obtained information or an image from the LP DAAC website, for instance from Outreach Materials, then we request that you provide information that can direct your reader to the LP DAAC website. For example:

ASTER Mount Gariwang image from 2018 was retrieved from, maintained by the NASA EOSDIS Land Processes Distributed Active Archive Center (LP DAAC) at the USGS Earth Resources Observation and Science (EROS) Center, Sioux Falls, South Dakota. 2018,
