Really cool data, Vipassana.. I currently have zero technology on my bike so I'm kinda behind in that area. You mind me asking what these images are from? Do you get all this with just a regular GPS unit? Comes bundled with software, I assume?
I'll definitely contribute to the thread when I get up to speed. The technology we all have available to us is just so damn cool.
I actually use a fairly old device called a MotoACTV. It came out in 2011 I think, but was super neat for the time. It has built in Bluetooth, GPS, and WiFi, water/dust resistance, and a screen which is highly readable in direct sunlight. It holds and plays music and has an android app that allows me to get notifications from my phone on the unit so I can see them while I ride (routes, texts, calls, weather). Like I said, it was very advanced for it's time.
I use it with the Motorola heart rate strap and their speed/cadence sensor. It has honestly always worked flawlessly for me, though I have nothing to compare it to. It never really got the appreciation I think it deserved because of it's high price at the time and the general lack of advertising. Most people who new about it were techy, non-athletic types I think. You can still pick them up really cheap now with their accessories being cheap as well, but it is getting pretty long in the tooth now and I think there are probably some better alternatives coming out with all these smart watches.
I'd also probably hold off on it because Lenovo recently bought Motorola and it's not clear how long they will continue to support the device or it's web portal.
But basically I use this device to track everything. It auto uploads the various workouts to the web whenever it finds a WiFi network it knows. Then I log into the webportal to view my workouts. They give you profiles and overviews, but I usually download the data and plot it myself in Microsoft Excel.
I've found some very neat websites that help you visualize/edit/convert all types of GPS files too. This is one of my absolute favorites:
