I used to not activate location services on my phone because I thought that would conserve battery power. Lately, I've been leaving it on so I can have a log of everywhere I visit. I learned that you can retrieve all of your old location data from Google, so I wanted to see if there was any interesting trends I could suss out.
You can download all of the data that Google has collected on you here. I checked off the Location History (JSON Format), which I downloaded as a .zip.
Also following the post, I plotted a trajectory graph:
I was intrigued by the inclusion of altitude information, so I wanted to see what a 3d plot would look like:
I didn't think it was super helpful....
From here, I decided on the first things I wanted to look at: what was going on when I was higher in altitude, and where were my most commonly visited places.
I decided I would filter the location dataframe by when my altitude was greater than 500 and then plot those points against a map.
I know I've flown to Cleveland for school and then Cincinatti for work. It is interesting to see that I was high in altitude closer to home; I'm not sure what that exactly corresponds to. I've also flown to more places in recent memory, but probably left my phone off...
Weirdly, not sure what the random dot is above Virginia.
Most Frequent Locations
Based on the command below, looks like info has been collected since the end of 2013. I decided to use a frequency of 300 as a cutoff.
I used the count() function from plyr to check the frequency of coordinates being used:
