From the Sensor Data Table, click on the icon below to view the participant's GPS data:
The table lists samples in reverse chronological order, i.e. starting with the most recent. Only the first 100 samples are displayed. To download the complete data file for the participant, click on the "Download CSV" link.
Notes:
- If your account is set up to only collect GPS at the time of survey completion then the GPS coordinates will be in the Rapid Report File along with the survey data.
- You may see more columns than are outlined in this guide. Different phones and services provide additional GPS data types. Here we cover the main ones.
