Cutting-Edge Hyperspectral from  Orbit

Core Imagery

Tanager’s planned core imagery data include calibrated radiance and atmospherically-corrected surface reflectance. These ready-to-use data products are intended for customers who want to utilize the full spectral range to extract application-specific insights.

Core imagery is planned to be available in HDF-5 format, unrectified or rectified. Imagery will be delivered through Planet’s APIs within 24 hours of image acquisition.

• Radiance - calibrated spectral radiance data for users interested in performing their own atmospheric corrections and custom analyses.
• Surface Reflectance - atmospherically-corrected reflectance data, processed using the ISOFIT family of algorithms, for users aiming to quickly investigate Earth's surface materials and properties.

Methane

Derived in partnership with Carbon Mapper, these products leverage state-of-the-art methane detection algorithms. Tanager’s planned Methane offerings includes Quicklook and Quality Controlled products described below.

Both offerings include GeoTIFF plume imagery, methane concentrations (in ppm-m), plume origin coordinates, and observation date & time.⁴

• Methane Quicklook - expected to be available through Planet’s APIs within 72 hours after acquisition with an initial emission quantification estimate for rapid leak detection and repair.
• Methane Quality Controlled - expected to be available through Planet’s APIs within 15 days after acquisition with reliable emission quantification estimates for improved environmental reporting.

⁴ Additional metadata includes emission uncertainty, wind speed, wind direction, and more.
