Geographical grid systems often require different resolutions to address use cases at different scales, and it can be valuable to have a hierarchical relationship between cells at one resolution and those at the next. H3 has a hierarchical system where parent cells approximately contain their finer resolution children. In this talk during Uber open Summit 2018, H3 project lead Isaac Brodsky describes how this system is constructed, what use cases are and are not approximate, and gives examples of use cases enabled by a hierarchical grid system.

At Uber, we use data for nearly everything from influencing policy to building products and gleaning market insights. However, the data alone doesnt always tell the full story. Color, composition, and framing play a critical role in developing a narrative that helps connect emotionally and visually with your audience. During our June 2018 Visualization Night, Uber Principal Designer Erik Klimczak discusses how the Uber Data Design team leverages data throughout the organization to build better products.")
