* The Social Atlas of the metropolis of Nantes is a collaborative
project of social sciences (geographers, sociologists, architects and
urban planners, historians, etc.) with the aim of providing visibility
to the social realities of the city [FR]


* A map of all the telephony towers build with the data from
collaborative project OpenCelliD to demonstrate the compression of XYZ
tiles. It usies the brotli algorithm to make fast and high-performance
visualizations with huge data volumes via @RealIvanSanchez


* Measurements of the TOPEX / Poseidon satellite altimeter reveal the
hidden energy of the tides and the influence of the topography of the
seabed on the dissipation of its force
