The current analytics platform will be discontinued after January 31, 2024, and will be replaced by new advanced processing functionalities. This change will affect projects, workflows, jobs, data blocks, processing blocks, and custom blocks. For more information, see the blog post.
Description
A data block that provides visually optimized Sentinel-2 images at processing Level-2A. These images are acquired by the twin constellation Sentinel-2A and 2B at a combined revisit rate of 5 days anywhere on the globe. The datasets are available starting with 2017.
See this block on the marketplace.
