New Product Release: GRUS Surface Reflectance Product

January 31, 2023

We will be releasing a new product to our GRUS imagery.

During the past few months, we have been working really hard to improve our data offering, and we believe that the GRUS Surface Reflectance (SR) product will help you enjoy your experience with AxelGlobe even more.

So what is the GRUS Surface Reflectance Product (SR) all about?

The GRUS Surface Reflectance product is generated for every GRUS tile on AxelGlobe. The values contained in the surface reflectance product have been corrected with respect to the atmospheric conditions at the time of acquisition. The process of atmospheric correction converts top-of-atmosphere reflectance (TOA) to bottom-of-atmosphere reflectance (BOA).

We expect this product to improve radiometric consistency and produce more accurate multispectral indices, especially when working with multi-temporal datasets and calculating real-world attributes such as biomass or LAI. This is achieved by removing atmospheric interference which can affect reflectance values according to the specific conditions at the time of data acquisition.
