GEOGRAPHY & CARTOGRAPHY CALCULATOR
Datamobility Entropy
A precise tool.
What is the Datamobility Entropy & How does it work?
Mobility entropy quantifies the unpredictability of an individual’s movement across a set of geographic locations. By treating each visited place as a state in a stochastic process, the entropy captures how evenly travel is distributed.
In cartographic analysis, higher entropy indicates a dispersed travel pattern, often associated with metropolitan commuters, whereas low entropy reflects routine, localized movement such as daily trips between home and work.
The metric is derived from Shannon’s information theory and can be combined with spatial weighting to reveal hidden structures in mobility networks, supporting urban planning and transportation modeling.
H = -\sum_{i=1}^{N} p_i \log_2 p_i

What is mobility entropy?
Mobility entropy measures the unpredictability of an individual’s movement across different places, indicating how evenly their travel is distributed.
How is mobility entropy calculated?
It is derived from Shannon’s information theory, treating each visited place as a state in a stochastic process.
What does high mobility entropy indicate?
High mobility entropy indicates a dispersed travel pattern, often seen in metropolitan commuters with varied movement.
What does low mobility entropy suggest?
Low mobility entropy suggests routine, localized movement, such as daily trips between home and work.
