We discovered a few brand count fluctuations as a result of updated sourcing and other metadata bugs. These corrections resulted in significant changes in the total number of POI for each affected brand, but the new count is correct. For transparency, we'd like to list some of these corrections as examples in no particular order:
- Chase (
SG_BRAND_cd8e7918010a87cc619849e00265c9a6). Net POI count change: US: -530 CA: 0. Bug: Previously included ATMs.
- Cardsmart (
SG_BRAND_137e699c352a2a85). Net POI count change: US: -95 CA: 0. Bug: Previously included places w/Cardmsart section in store (not stand alone store).
- Park National Bank (
SG_BRAND_2b18e4fd0b6de0e2). Net POI count change: US: -77 CA: 0. Bug: Previously included ATMs.
- GUESS (
SG_BRAND_44fc6c9812b78f5e76f9b25892fe6ad9). Net POI count change: US: -153 CA: -48. Bug: Created additional child brands (e.g., Guess Factory, Marciano by Guess) which include POIs previously branded as GUESS. Also had duplicates with pre-existing child brand G by Guess.
- Calvin Klein (
SG_BRAND_ba56feb34cfc3912b55a4c2429a44319). Net POI count change: US: -82 CA: -4. Bug: Removed duplicates.
- Chase (
Our current scope of a "place" is anywhere consumers can spend time or money. This has not changed as a whole, but we've made an exception to start sourcing industrial POIs such as warehouses, distribution centers, and B2B equipment/machinery wholesalers. 🚧 🏗
As of this release, SafeGraph Places has ~8,500 industrial POIs across 20 brands including Caterpillar (
SG_BRAND_b36725e851150ae2a6e85ce2e48d8193), Amazon Distribution (
SG_BRAND_fc2573e1b20d6dd1), John Deere (
SG_BRAND_e16bb3b801ef62207574cb693cf57797), and International Trucks (
6,865 of these industrial POIs also have foot traffic data in Patterns
Category Fill Rate -- We monitor category fill rate with 3 metrics: (1) category fill rate across the entire dataset, (2) category fill rate for branded POI, (3) category fill rate in the brand_info file (brand-level categories). We want all of these numbers to be 100%.
(1) All POI category fill rate. Last month 98.8%. This month 99.2%.
(2) Branded POI category fill rate. Last month 100%. This month 100%
(3) Brand-level category fill rate (brand_info file). Last month 100%. This month 100%
See the August Release Notes for details on our new and improved category ML model. 🎉
We constantly ingest data from new sources, and many
safegraph_place_ids(sgpids) are intentionally dropped, but we are unable to track each and every dropped sgpid. In this release:
- We dropped 77,033 sgpids (20,908 branded and 56,125 non-branded).
- 22k due to stale sourcing and redundancy
- 2,784 dropped as a result of bug fixes for branded POIs
- 10,037 dropped as a result of deduplication 👯♂️
- 29,449 dropped due to permanent closures (dropped but not lost -- you will still see these POIs if you get the closed_on column).
The remaining drops are undesired failures to maintain a consistent sgpid between releases - known as bad sgpid churn (see discussion in March 2019 release). We are continuing to work on better metrics to distinguish good vs. bad churn.
We are thrilled to introduce two new Geometry columns! 🚨 🎉
building_heightis the height above ground in meters when a POI's polygon is a building. This column has a 25.1% fill rate and is not available in Canada. See the Places Manual to learn more.
enclosedis a boolean (true/false) column. When
enclosed= TRUE, it means the POI is completely enclosed indoors by its parent and is only accessible by entering the parent structure. This provides deeper context around spatial relationships, and it also sheds light on how we treat enclosed POIs when building Patterns. When a POI is determined to be
enclosed, we intentionally exclude it from receiving visits in Patterns and instead roll the visits up to its
parent_safegraph_place_idbecause the accuracy of mobile GPS data deteriorates within large, indoor structures. For the nitty gritty on how we derive the
enclosedcolumn, see the Places Manual.
📣 While OWNED polygons are preferred, it does not mean that SHARED polygons are inherently bad. It only means that the exact shape of each POI within the polygon is not discernible, but the general location can be identified by looking at the centroid (
Historically, we have measured
polygon_class = "OWNED_POLYGON" for all POIs that are both (i) branded and (ii) do NOT have a
parent_safegraph_place_id; we call this group "branded, no-parent".
With the introduction of the
enclosed column, we can refine this metric to measure "OWNED_POLYGON" for all POIs that are both (i) branded and (ii) have
enclosed = FALSE. When
enclosed = FALSE, it indicates that there are reasonable means to derive a unique polygon for the POI (even when
parent_safegraph_place_id is not null), and we should strive for 100% of these POIs to have polygon_class = "OWNED_POLYGON." See the Places Manual for more about
- Last month, the percent OWNED polygons for branded, no-parent POIs was 80.2%
- This month, the percent OWNED polygons for "branded, non-enclosed" POIs is 78.8%
- Here is how we're tracking on this metric across releases: OWNED vs SHARED Polygons in SafeGraph Places Release History.
- Centroid-Radius Polygons -- As discussed in March 2019 release notes. We internally track centroid-radius polygons vs precise polygons and strive for 100% precise polygons. You can measure this yourself using the
- This release, we improved to 95.9% precise polygons (95.5% last month)
- Here is how we are tracking on this metric across releases: Centroid-Radius Polygon Tracking.
In last month's delivery, SG Patterns had 4,091,868 points-of-interest (US only). This month, SG Patterns has 4,078,861 points-of-interest (US only) (net -13,007).
Last month, SG Patterns had 818,376,187 visits from 32,786,255 visitors. This month, SG Patterns has 868,811,661 visits from 35,455,162 visitors (delta + 50,435,474 visits, + 2,668,907 visitors).
