Open source Project for a Network Data Access Protocol (OPeNDAP) is a protocol for accessing and transporting distributed scientific data. It provides users (i.e., OPeNDAP clients) simple, remote access to large collections of data sets via the internet through HTTP.
OPeNDAP can be a particularly appealing solution for accessing large amounts of data due to:
- Ability to aggregate data from multiple files (e.g., time-series) in one transfer operation.
- Capability to retrieve and serve subsets of files.
- Does not require knowledge of native data storage format.
During this webinar users will be shown three different NASA Earth Observation System Data and Information System (EOSDIS) instances of OPeNDAP and learn how to leverage these implementations for accessing NASA Earth science data.
- Provides universal access to a variety of biogeochemical scientific data products.
- Provides ability to integrate distributed data products from multiple OPeNDAP services into your workspace (e.g. R) for analysis (demo)
- Middleware Services- Quick Overview
- Web-based - Extract data values from MODIS layers for point locations using AppEEARS.
Part 3: OPeNDAP, EOSDIS and Additional Tools - NASA's Atmospheric Science Data Center (ASDC)
- EOSDIS/OPeNDAP Collaborations - Big Earth Data Initiative (BEDI) and Earthdata Search
- Use Cases - Tools that can access OPeNDAP (Panoply, ArcGIS Pro, etc.)
