Nice article. Couple of questions: 1. Curious about the H3 near the end. Why did you choose H3 resolution 10 for the tessellation? That seems very coarse for buildings. You end up with maybe 20 buildings per H3 index. I guess it depends what other data you want to join to your buildings and what resolution that is. 2. Would it not make sense to keep the WKT representation of the buildings, so that higher resolution spatial joins can be done as needed - rather than totally abstract to the H3 cell id? Thanks.
