Planningland Use Mix
A precise tool.
What is the Planningland Use Mix & How does it work?
Land‑use mix describes how different functions—residential, commercial, industrial, and open‑space—are distributed across a planning area. A balanced mix can reduce travel distances, support local economies, and improve livability.
One way to quantify this balance is by using Shannon entropy. Entropy treats each land‑use share as a probability and measures the uncertainty (or diversity) of the composition. Higher entropy indicates a more even distribution of uses, while lower values point to dominance by a single category.
Because the maximum entropy for n categories is ln(n), the raw value can be normalised to a 0‑1 scale, making it easy to compare sites of different complexity.
H = -sum_{i=1}^{n} p_{i},ln p_{i}
pi = proportion of land‑use category i

Frequently Asked Questions
What is Shannon entropy in the context of land use?
Shannon entropy measures the uncertainty or diversity of land-use distribution. Higher entropy indicates a more balanced mix.
How does this calculator help in planning?
It helps by quantifying how evenly different land uses are distributed, supporting decisions that reduce travel distances and improve local economies.
Can I use this for any area?
Yes, you can input data for any planning area to assess its land-use mix diversity.
What does a higher entropy value indicate?
A higher entropy value indicates a more even distribution of residential, commercial, industrial, and open-space uses.
How do I interpret the results?
Interpret results by comparing entropy values; higher values suggest a more balanced land-use mix.
Is this calculator suitable for urban planning?
Yes, it is particularly useful for urban planners looking to assess and improve the diversity of land uses in their areas.
Can I input my own data into the calculator?
Yes, you can input your own data on land-use shares to calculate the entropy for your specific planning area.
