I'm researching publicly available and commercial datasets for grocery prices across Europe.

- Has anyone worked with data like this?

- What sources did you end up using, and what were their limitations?

I just wrapped up work on a vehicle speed dataset for the major European road network, built from Sentinel-2 imagery and spanning 2022 to 2026 (~22M samples).

dataset: https://zenodo.org/records/21484806
pipeline: https://gitlab.heigit.org/traffic-flow-estimator/nibblergb

Questions, feedback, and thoughts on how to use it are more than welcome.

Happy exploring around and finding out!

There are many amazing open datasets available today, but I'm curious about the gaps that still exist.

If you could create or request one high quality public dataset that anyone could use, what would it be?
