Safegraph and Advan data connection
We were working on the Safegraph and Advan data. We noticed that Advan has "RAW_NUM_CUSTOMERS" and Safegraph has "RAW_VISITOR_COUNTS". Are these two variables connected?
Understanding backfills
I am wondering how the backfills actually work in the weekly patterns foot-traffic data. I understand that they are generated monthly, whenever a new Advan POI is added to the dataset and that this basically constitutes a back-attribution of past traffic in that POI's polygon. Does this revise any of the visit counts for nearby POIs? For instance, say I have two businesses next to each other and one is newly identified as a POI. Does the algorithm re-attribute some of the visits that were previously recorded under Business A to the newly-added Business B?
Advan weekly pattern branded POIs
Hi Sir/Madam,
I hope this email finds you well. I appreciate it if you can share insights on three questions I have about branded POIs.
Data Definition Questions
-
I can’t understand what the difference is between these two variables, as they appear to share the same definition. Could you please help clarify?
WORK_BEHAVIOR_DEVICE_HOME_AREAS - This column is the same as work_hours_device_home_are as but only includes devices that dwelled for at least 6 hours and excludes devices whose visit is in the same gh7 as their home location.
DEVICE_DAYTIME_AREAS - This column is the same as work_hours_device_home_areas but only includes devices that dwelled for at least 6 hours and excludes devices whose visit is in the same gh7 as their home location. -
Regarding DISTANCE_FROM_PRIMARY_DAYTIME_LOCATION, does this intend to capture only local trips (i.e. errands) using the “work” location as the base, or, does this capture all trips (including commutes to/from home) utilizing the work location as the base? This is to say, if I am interested in understanding commuting behavior of people based on the location of their employment (not based on the location of their home), does this variable speak to that?
Advan definition of visits for visits by each hour
I was looking at the definition of visits in the Advan FAQ, which states that a single device can only contribute to visits once per day. How does that work ith the visits by each hour field?
Advan data errors starting in June 2023
I see a large number of POIs that had an enormous and usually permanent drop in visits/visitors starting in June 2023. This drop is especially prominent in NYC. I can't find any explanation for this.
Missing POI - Help
Hello, I am working with Advan data and looking for specific data for a POI. However, it is missing and I cannot triangulate it with lat/long data either.
Placekeys Found in Advan, not in POI Dataset
I'd like some clarification around discrepancies in placekeys between Advan and Safegraph.
