Welcome to the new OPeNDAP website!
OPeNDAP is used by data users, data managers, data providers, and software developers. See how our protocol and organization works to support collaboration and innovation.
OPeNDAP allows researchers and other users to remotely inspect data, subset specific portions, and download it to a variety of analysis environments.
Find out how OPeNDAP can simplify workflows for complex data projects, especially those with distributed teams and challenging or legacy datasets.
OPeNDAP reduces data costs and makes it easier for end users to retrieve and manipulate data. See how NASA DAACs and other providers leverage OPeNDAP.
See how developers can modify and extend our open-source code to create custom solutions for specific data transfer needs.
Ready to get started? Download the software now*, or check out our community-powered Support pages for tutorials, FAQs, and more. (Developers can head to Documentation to use our open-source code in their own projects.)
*The Hyrax data server is one of many servers implementing the OPeNDAP protocol. It’s free to use and fully open source.
