I am asking because i know crawler robots exist and are in use since at least a few yearse. The more interesting aspect imo. is the automated image recognition which made huge improvements over the past years. For that it makes sense to have the analysis centralized within reason. E.g. pattern recognition against a larger database. There is local factors too though as materials, construction forms and so on often have historic local differences.
