It sounds a little like homework, your bio suggests otherwise, but geographic data is very interesting, so I thought I'd give it a bit of a comment!
If you have location tracking in Google turned on, which the data can be downloaded, you can determine many things.
You will need to enrich your data with extra GPS data sets of locations of schools, shops, particular buildings, places of worship,
Some for examples of what can be determined ...
- During a 'work day' you can determine a 'normal place of work'.
- In the 'evening' (for most people) the gps locator will become static, this is a good indication of 'home'
- You can probably infer if a person has children if they go to a primary or secondary school at 9am and 3pm. You can guess at their ages depending on the type of school.
- By following the route between 'work' and 'home' you can determine, by the congruence of roads or rail networks, and the locations of bus stops / train stations, the mode of transport.
- If the data you have enriched is detailed enough, you can determine an individual's choice in lunch options.
- If there are periods of increased velocity, depending on the time of day, you can determine that they perform exercise, either by running or by pushbike. Further to that you might be able to determine the consistency of their fitness resolve by the frequency and duration of their exercise.
- You can start building a more detailed profile of the person, by looking at how often they eat out, if they attend church, if they go to sporting matches, what team they support, where they get their car serviced. All these things can give insight into an individual with regard to their lifestyle, habits, preferences, affiliations.
