These days I have some work on gps trajectories. I’d like to view those gps data on the map, so as to check whether some assumptions can make sense. After a little bit of searching, I find this work on github: essoduke/jQuery-tinyMap. Based on his work, I make a very simple demo which can plot several trajectories on Google Map.
This demo is very easy to use. Just open the index.html, you will get:
Usage
Input Format
The input format is as:
textarea = trajectory[;|\n]trajectory[;|\n]trajectory ...
trajectory = location|location|location ...
location = longitude,latitude
Every input may contain several trajectories seperated by ' or \n.
Every trajectory contains a serials of locations, which is separated by |.
Every location is composed with longitude and latitude in the form of longitude,latitude.
Buttons
The Points Button is to plot every gps point in the trajectories on the map. After plotting, the map will be centered to the geometry center of those points.
The Routes Button is to plot every trajectory with a blue line on the map. After plotting the amp will be centered to the last plotted trajectory’s geometry center.
The ClearAll Button will clean up all those plotted layers.
