I was looking at the Monthly Patterns - Free Historic Data for airport visits in Pittsburgh. When I query the data, I see the following three places:
The total number of visits to the airport seems missing in the data. Any help would be greatly appreciated!
Hi @mceldir, thank for writing in. I found this blog which might be helpful. Airports have a lot of parent/children polygon, and if they are fully enclosed they don’t include foot traffic. (I don’t know if this is the reason for your specific example, but it’s a guess!)
"Children that are enclosed (enclosed == True) are basically not distinguished from their parents. They do not have their own separate foot traffic data. Sometimes they have their own polygons, but sometimes they’re just a part of the parent polygon, although they may have their own latitude/longitude data.
Children that are not enclosed (enclosed == False) have parents but also act as independent locations. We track visitor data like visits_per_day separately for those locations, and they have their own polygon data in the polygon_wkt column."
Thank you @evan-barry-dewey! This is definitely helpful.
I am encountering an issue similar to the initial post here that is not addressed by the parent/children data structure. I was hoping to do a tally of visits to children location within Los Angeles International Airport with Advan data, but finding spotty coverage, I was hoping to get at least total visits to the airport.
I ran into the following issues:
- There is no visit count for the Los Angeles International Airports POI (at least for October/November 2023)
- Some of the POI included in Safegraph do not seem to be in the Advan data.
- In Safegraph, I found that many locations that should be children to the airport are not (e.g., restaurants inside the terminals) and that the parent/children relationship sometimes doesn’t make sense (Terminals are children of the American Airline Lounge, which is, itself, child to the airport). making it difficult to aggregate children locations.
I understand that airports are probably some of the most complex POI to deal with, but I would like to know if point number 1 can be addressed (i.e., getting visit count to the entire airport complex)?
