Data Products

Dedicated processing chains will be designed, implemented, and operated to elevate the Tandem-L raw data to higher level products. The main information products under investigation are related to “Deformation” and “3-D Forest Structure”. Following tables list currently defined information products, mirroring the user needs and specified for area coverage, spatial resolution and accuracy of the derived product.
