tracing ability "people profile"

[Suhad Faisal]

Hello 

I wonder if gama has a tracing ability to make "people profile" for people movement and then clustering these people in groups according to their path profiles.

thanks

Hi,

Not directly, but you can easily save each location of an agent inside a list of point, and  build the corresponding polyline:

species people skills: [moving] {

      list<points> previous_loc;

       geometry trajectory;

       reflex move {

              do wander;

              previous_loc << location;

      }

      action build_trajectory {

              trajectory <- line(previous_loc);

      }

} 

Concerning the comparison of trajectories, I have no idea how to do that, but if you are able to build measures of proximity between trajectories, you can use the weka plug-in to do some clustering on it.

Cheers,

Patrick
