Discover NASA Land Processes Data with Web Services


Published: March 18, 2016


This is a LEGACY RESOURCE. It is no longer maintained but is usable with minor adjustments. This resource leverages NASA's Application for Extracting and Exploring Analysis-Ready Samples (AppEEARS). AppEEARS has been deployed in NASA's Earthdata Cloud space. You can access AppEEARS using the new link: For up to date information on using the AppEEARS API and examples, please see the AppEEARS API Documentation. If you have questions, please contact LP DAAC User Services (

The Big Earth Data Initiative was undertaken to facilitate work to improve data access capabilities for all users of NASA Earth Science data. The LP DAAC responded to the initiative by creating a new strategy for making land processes data available via web based services. The LP DAAC deployed data access services (OPeNDAP) to provide access to data, Middleware/Metadata services to provide information and details about the data, and then developed User Interfaces (UI) and Application Program Interfaces (API) to utilize and consume these services to provide the specific data that users desire. This presentation will show how these different levels of services were created and how they can function together as a tool for users to gain specific insight into the data provided by the LP DAAC. The LP DAAC’s AppEEARS point extraction tool capabilities will also be explored and explained.
