What is the Social Density Map?

General Information on Socal Density Mapping

  • To help community members ensure social distancing in order to limit exposure to COVID-19, we’ve built what we’re calling a “Social Density Map”

  • Areas of high “density” will show in deep purple color, while lower density areas will be a lighter shade of purple/pink.

  • The map uses data from the approximately 3,000 wireless access points across campus to provide a general idea of the density of people in a given area.

  • However, the data is imperfect for a variety of reasons:

    1. Point-in-Time - The data is a snapshot of a previous point-in-time (captured every 15 minutes), so it will not provide a real-time view of activity.

    2. Devices, Not People - The data shows devices, not people. People could have multiple devices connected to a single access point, which will appear as a higher density.

    3. Connected Devices Only - The data only shows devices connected to our wireless network (including guest). Devices not using the network (e.g. someone using their wireless carrier's data network) are not included.

    4. Locations - Due to the nature of WiFi, device location predictions are not precise and a variation of ~15 Meters is expected. This means that occasionally a device will be a floor above or below the location indicated.

  • The map includes high-traffic buildings, such as the ELC, and academic buildings.
