NASA Unveils Archived Satellogic Multispectral Data: A Comprehensive Guide
NASA's Commercial Satellite Data Explorer (CSDA) Program has recently made a significant addition to its offerings, providing researchers with access to high-quality, Earth observation data from Satellogic's NewSat constellation. This Level 1D product, equivalent to a NASA-defined Level 1C data product, is a treasure trove for Earth science enthusiasts and researchers alike.
Key Features of the Data Product:
- **Multispectral Camera: Each satellite in the NewSat constellation carries a multispectral camera, capturing images in four distinct bands: visible (red, green, and blue) and near-infrared parts of the electromagnetic spectrum.
- Spatial Coverage: The product offers images covering an impressive 25,000 square kilometers (km2) of the Satellogic archive, providing a comprehensive view of specific areas.
- Data Accessibility: Researchers can access this valuable data product through the SDX, NASA's powerful tool for searching, discovering, and accessing various Earth observation data.
How to Access the Data:
- **Authentication: Researchers will need to use their Earthdata Login credentials to authenticate and initiate data download requests.
- Metadata and Documentation: The product includes all associated metadata and documentation, ensuring researchers have the necessary information to understand and utilize the data effectively.
- End User License Agreement (EULA): The use of this data is governed by the USG EULA, which researchers must agree to before accessing the data.
About SDX:
SDX is a powerful platform that allows users to explore and access a wide range of Earth observation data, including GNSS, DEM, SAR, multispectral, and precipitation radar data acquired through the CSDA program. It offers:
- Streamlined Data Download: Users can easily download the data they need.
- Automated Quota Tracking: SDX keeps track of data usage, ensuring researchers stay within their allocated quotas.
- Coverage Map: A new coverage map provides a high-level overview of the spatial coverage of the data discoverable through SDX for any specified month and year.
Accessing Data from SDX:
To order data from SDX, users must:
- Create an account with NASA Earthdata.
- Log in to NASA Earthdata.
- Agree to the terms of the EULA.
- Note that all data requests must be approved by CSDA data managers.
About the CSDA Program:
NASA's Earth Science Division (ESD) established the CSDA Program to identify, evaluate, and acquire data from commercial providers, supporting NASA's Earth science research and applications. This initiative recognizes the potential of commercial satellite constellations to advance Earth System Science and benefit society.
