Hi, I want to ask two questions about the “what part” and “where part” in placekey. I found that there are two formats of “what part”, 3-digits and 6-digits. And I want know which one is unique if we want to identify a company and find out its daily visit. Could you identify two companies if there are right next door to each other? If not, in what kind of situation can you distinguish two companies if they have the same 3-digits “what part”.
Another question is that in some cases, if I (1) only use address info; (2) use address info + company name, I will get placekeys with different “where part” in these two situations. And I calculate the distance of the two “where part” placekeys, the mean is 203 meters, the median is 134 meters, and the max one is 9km. Could you please tell me why this happens and which one should I choose to merge with Patterns data?
