Hi Safegraph team, I was wondering if Safegraph would assign the same id to different stores at the same location. I noticed that Safegraph tracks many POIs of their monthly patterns of raw visit counts before the POI opens, and continues to track their foot traffic after they close.
This topic was automatically generated from Slack. You can find the original thread here.
If each store had a unique safegraph_place_id too, I was wondering what could be the reasons that Safegraph could have records for their visit counts/visitor counts before these stores open or after they close dates which are documented in local newspapers
Hi , please see this note under “Visit Nuances” in our docs:
> Relationship with POI opening and closing dates - Where the dates of POI opening and closing are known (see opened_on and closed_oncolumns in Core Places, no visits will be attributed to the POI before the opened_on date or after the closed_on date. If these dates are not known, it is possible for the algorithm to mis-attribute visits for those POIs (e.g., after a POI has closed in real life but where this knowledge has not yet been captured in our data).
In other words, even if stores have open and close dates documented in local newspapers, those might not be captured by our Core Places data and so visits could be mis-attributed in that case. That would explain what you’re seeing.
Hey ! Just confirming that we answered your question. I’m going to go ahead and close this thread out. If you have any more questions or follow-up questions, we’re always here to help! Just be sure to make a new post to safegraphdata, as we aren’t monitoring old threads at this time. Thanks!
