Step 2: 2.Converting Data With Processing.

Converting data to the format that cartodb can read.

2.1, Manually delete the NULL data for your GPS doesn't work sometimes.

You will get something like this

Step 3: 3.Map It With CartoDB:

I chose to do heat map with animation.

And some of the key parameters for understanding the animation is:

steps: divide the whole process into how may steps

durations: animation time
resolution: decide how isolate the cluster should be.
