Product Processing

Pixxel provides satellite imagery in the following product bundle:

• L2A : Map-projected Bottom-of-Atmosphere (BOA) reflectance image (This is the default product unless otherwise specified).

Name	Description	Product Level
Bottom-of-Atmosphere (BOA) Reflectance	Radiometric, geometric, and atmospheric (aerosol and water vapor) corrected data. The imagery is orthorectified and projected in WGS84. Delivered in GeoTIFF format with accompanying metadata.Pixel values are scaled between 0–50000. To convert values to physical reflectance (0–1), divide all pixel values by 50000.	L2A

Atmospheric Correction

Isofit is the model used to process Pixxel’s hyperspectral imagery. It performs atmospheric and sensor correction to transform raw satellite data into accurate surface reflectance, enabling reliable analysis across various applications.

By modeling the interaction of light as it passes through the atmosphere and is captured by the sensor, Isofit ensures that the resulting imagery accurately represents real ground conditions—crucial for use cases in agriculture, environmental monitoring, and more.

Isofit is highly flexible:

• It can operate on both individual pixels and entire images
• It supports multiple atmospheric models and sensor types, making it adaptable to diverse datasets and conditions
