Sentinel-3 and Sentinel-5P

[guillemc23]

Hi everybody!

I'm thinking of a way to display data from Sentinel-3 and Sentinel-5P, which come in .nc files with more or less complex format. Ideally, I wouldn't want to transform the raw data, but instead use it as is and build a TiTiler adapter to properly read them.

Has anybody done something similar? Any ideas how to proceed? Is it a good idea to perform these kind of on-the-fly transformations in TiTiler instead of preprocessing the products so they are already structured how TiTiler likes them?

My main concern is how geographical coordinates are stored within these netcdf files, since these products are not a straightforward use case. For example, when opening the PRODUCT group of a Sentinel-5P product, the variables are referred to a coordinate called ground_pixel, and latitude and longitude are just some other variables inside the product also referred to ground_pixel, iirc.

Thank you!
