Topic: Heat map overlay for tracks
Good evening Wialon
Would you consider the inclusion of a 'heat map' visualization within track playback?
A heat map is a graphical, visual overlay over geolocation data that shows a scale of colour increasing from green to red as the clustering in particular area increases - in this case, indicating the plotting of GPS points. Refer to the below image as an example.
When tracks for multiple units are loaded with different track colours, it can sometimes be overwhelming to look at a 'busy' location, and hard to make sense of any information.
I see two situations this could be used in:
1. Where a client wishes to load a series of tracks over an extended period that will show a lot of dense tracks in a location, the colour of the overlay would increase from green to red. This immediate visualization will inform the client that a unit has been in that location for either a considerable length of time, or has visited that location on a number of occasions - based on the intensity of the red colour. This would also work for routing, too.
2 Where two units converge or become inter-related in a close geographic location, the colours could change from - say - pink to purple, showing immediate points on the map where the two units have been in close proximity with one another.
This feature would allow for:
Immediate reckoning of information through visualization,
More efficient track playback, when looking for data relating to either points 1 or 2,
Identification of units meeting at certain points on a route or track that they should not be meeting in
Allow for quick visual analysis of common routing, without having to establish route geofencing.
Thoughts? I certainly see merit in this visualization.
Happy to discuss further.
