+This is especially true for level 1 data which is typically raw radiance/reflectance observations.
 There are often many domain-specific transformations that can completely make or break the success of the ML task.
 `rs_tools` seeks to lower the barrier to entry cost for ML researchers to make meaningful progress when dealing with remote sensing data. 
 It features a standardized, transparent and flexible procedure for defining data and evaluation pipelines for data-intensive level 1 data products.
