Eighteen months ago I wrote about redesigning my site’s front page and mentioned in passing that I’d also created a page for every day which aggregated many things:
I’ve created a page for every single day that pulls together the day’s bits and pieces. It doesn’t aggregate everything I’ve done — yet — but it’s worth it for me just to have a daily archive of my Twitters. Most dates on the site link to the relevant page; here’s an example of one.
I’ve now taken this a step further and added a map for every day which aggregates various pieces of location-based information about me. Here’s an example of that.
Here’s a screenshot for posterity:
I realised that I was generating a few bits of location data every day and so, without actively doing anything more, I could keep a rough track of where I’d been. There are three main sources of data, all of which are aggregated on the same maps:
Located tweets. If I tweet from my iPhone, and I’m out and about, I’ll usually have it send the current location. So, seeing as I already grab all my tweets to display in the sidebars of date-based pages on this site, it was easy enough to also grab the latitude and longitude, where present.
Foursquare check-ins. I’ve been using Foursquare for a while, without being entirely sure why. It rarely, if ever, results in serendipitously meeting friends. But I liked the graphs it generates which made me think the data might be useful someday. A while back I started having it send check-ins as tweets to a private Twitter account that I’m using for such automated things. (Thanks to Russell for that idea.) So now I’m grabbing and archiving this Twitter feed and using the Foursquare tweets for map locations.
Flickr photos. Whether I take a photo with my iPhone and use its location, or manually position a photo on the map after uploading to Flickr, all those photos make for a lot of location data. So they’re on the maps too.
All of which means that for most recent days there are one or more points that show where I’ve been. Here are some examples, showing good and problematic things:
14 March 2010, while I was in Austin, TX, for SXSW. A mixture of photos and located tweets, also showing how useless the iPhone’s positioning can be: point 4 should have been from the convention centre, rather than a park I’ve never been to. In case you can’t guess, the numbers indicate the order in which the events occurred.
15 March 2010, from the same trip. Point 5 (and 9) aggregates several tweets that were at the same location — at the moment I assume consecutive tweets/check-ins/photos within 0.00025 of a degree in both directions are the same point. This page also shows some confusion over days and time zones: Points 1 and 2 were actually the previous day in Texas. I’ve tried to ignore time zone differences from all these sources in the hope of preserving my sanity.
18 March 2010. After Austin I went to New York and, although I didn’t record and transmit any location information while there (data roaming charges being expensive, and wi-fi more scarce), the photos I took and subsequently positioned in Flickr provide a nice map of some of the places I went that day. Similarly for days like this in Morocco in May, although some of those positions were guesses a few weeks later.
7 August 2010. A Saturday in London, combining Foursquare check-ins and tweets. Point 4 aggregates a Foursquare check-in and a tweet that were from the same location but had very slightly different lat/long data. The rest of the page features plenty of other stuff I did online that day.
24 August 2010. When most of my London-based weekdays look pretty much the same, a few dots around Shoreditch, a map view makes unusual days stand out. This one shows me going to a few places (as a non-located tweet says in the sidebar, “a pleasant afternoon of flaneuring”) before popping to Heathrow Airport later. That’ll be nice to see and remember in the future.
This idea isn’t to highlight content that’s fascinating to other people — these date pages aren’t even particularly obvious on the site — but are a manifestation of aggregating whatever data I can about myself. Save it now as you don’t know what or when it will be interesting. Given that so many of us are constantly leaving footprints across so many loosely-joined online places I can’t help feeling it should be easier for people to (a) archive and save such data and (b) view it all in one place.
One further thought… I was surprised that although much of this data is available online already — my located tweets and photos are public, although my Foursquare check-ins are only visible to friends on the service — putting it all on daily maps made me feel uneasy. It suddenly felt much more transparent and “stalkerish.” Seeing a single point on a map, for a tweet or a photo, is one thing. Looking through my history and seeing where I’ve been regularly, and recently, feels odd.
As a result of this the site currently doesn’t show maps for the past week. This isn’t a huge change, and it’s not even particularly logical, but it does feel slightly better. As Tom put it, this emphasises the archival nature of the concept, rather than the “where am I right now?” idea. I’ll see how it goes.
Which is a demonstration of why privacy is such a really, really difficult thing to deal with. If I can’t even work out for myself when I’m invading my own privacy, deciding on policies for thousands or millions of very different people using a service is a big problem.
Anyway, there we go: a map for every day.
