There's an interesting article in Wired: Know Thyself: Tracking Every Facet of Life, from Sleep to Mood to Pain, 24/7/365

This gives a nice overview of life logging, something which I'm building GPSLog Labs to do. GPSLog Labs helps quantify a lot of your daily activity based on GPS tracks recorded with cheap and simple GPS data loggers. By simplifying the process of analysing these logs it's possible to not just get total mileage you've traveled, but also the amount of time you spend at different places and doing different activities.

While it can't yet come close to something as comprehensive (and nice to look at) as the Feltron Annual Report, the GPSLog Labs reports are heading in that direction. The summary of your collected data can be exported in CSV format if you're keen enough to want to make something that looks really good!

There's a new publicly accessible page that shows the total activity of all GPSLog Labs users, broken down by day of week, month, and time of day.

I've just added a new breakdown by time of day on the stats summary page. This will show your total activity logged by the hour of the day when the activity started. It also breaks out the times by tags and places, the same as the by day of week and month breakdowns. It is interesting to see how your commute times, exercise times, vehical usage patterns vary.

This isn't an option I particularly want anyone to use, but you can now delete your account via your profile page. It's your data so you get to decide what to do with it, and if you want to leave for whatever reason, we'll try and make it easy.

This will remove all your data from our servers so you'll probably want to download your logs and export your stats before doing that.

Of course, since there is an automatic signup via OpenID, you'll still be able to login, but what you see will be a new empty account.

The confirm stage of the upload process has been simplified. Now when uploading a log, you no longer have the option to "remove segments", just to merge segments. This is because anything you could do with remove can be done with merge and there's one less scenario to worry about now.

1. Clicking the checkbox in the Merge segments column will merge the two segments into a single segment
   
2. The row will go red to indicate the cut will be removed
   
3. The change will be applied when you click the Save Log File button.
   

More details can be found on the Inbox help page.

GPSLog Labs now supports OpenID to allow you to sign in with an account you already have, rather than trying to remember yet another user name and password.

As a bonus, there is now zero-registration required. Sign in and you can upload a log and get started straight away!

I've just added a new Heading vs Time graph to the log detail "Other Graphs" tab.

This is linked to the Speed vs Time graph, so that zooming the Heading vs Time graph will zoom the Speed vs Time graph to the same area.

You will need to click the "Reprocess" menu command to see the graph for logs that were uploaded before this graph was added.

GPSLog Labs reports now show a selection of date range filters: In addition to calendar years, you can now view the report for individual months, the last 365 days, the last month or the last week.

Here's something I've been playing with for a while that is now trivially easy using GPSLog labs: Merging GPS log files into a single KML file for viewing in Google Earth.

You can select a group of logs from any place where there is a tab of logs (a tag, a route, a date etc.):

1. Click the "Select All" link on top of the table, then click the yellow "Select All" checkbox that slides out under that.

2. Choose Google Earth (KML), and select the following options (you must select Merged otherwise you will get a zip file containing the individual logs):

Simplify: This will reduce the number of points in the file by throwing away any points that are not necessary to define the shape of the tracks. i.e points along a straight line will be removed leaving only the end points.

Points: Output a small marker at each log point.

Lines: Output a line connecting log points.

Floating: If this is ticked, then the points will "float" above the ground according to their logged altitude reading. If it's not ticked, all logs will be "clamped" to the ground level.

3. When you click Download Selected Logs you'll get a Google Earth file like the screenshot.

It's really cool to zoom in on a road you travel along a lot and see all the tracks woven together. You can also get some interesting variations by playing with the various KML generation options:

This blog will keep you up to date on the latest news for http://gpsloglabs.com. I'll post feature updates, tips, and some insights into the technology behind GPSLog Labs.

GPSLog Labs is a site where you can upload logs from your GPS tracking device and map, graph and analyse them.

It will let you track your exercise and training whether your a cyclist or runner, and can also be used to track your mileage and keep a diary of your activity.

The site is now in a preview release or public beta and I encourage anyone who is interested to sign up and try it out. I'll be fixing bugs, monitoring scaling issues on the back end, and adding more features before going into a more public release soon.

I appreciate all your comments and suggestions and hope you get a lot out of the site.
