Unacast
- A company that captures and re-sells smartphone location data.
- Social Distancing Scoreboard
- 500,000 daily active users in Colorado, 2000 mobile apps
- 110 million MAU in US?
- 12 mo contract, $2500 per month, daily csv file ($30,000 per year)
- $3500 per mo for state, $9000 for US
- Tesh Patel
- Brian, Mo, Colin, Harris, Christy at BCPOS
- neighborhood level and device level
- data samples: neigh level 12/1/19 - 4/28/20; device level Monthy of May 2019, May 2020, and June 2020.
Data format and size
- Neighborhood level; attributed shapes stored in a single csv file; 7 - 10 mb for OSMP/BCPOS combined extent
- Device level; tabular xy coordinates in 50 csv files; 8-9 GB for the state, 100 million records; 4.7 million in our extent
Analysis 1: Trail heat
Analysis 2: March 2020 Distance to Home
Analysis 3: Device level
Analysis 4: Day in the life
Analysis 5: HCA travel
Analysis 6: SNAPP proposal
Data quality and limitations
- Proof of concept seems strong (can see patterns among trails, and trends in time)
- Signal breaks down for less visited places
- 10x underestimate visitation
- Includes BCPOS and OSMP
