What is urban morphometrics

Not anything new!

What is urban morphometrics

A study of urban form through the means of quantitative assessment of its constituent elements.

Conceptually similar to historico-geographical approach.

Methodologically embedded in spatial data science and geography.

Morphometrics in 2025

availability of data

evolution of software

performance

automatised pre-processing

all that pushes the limits of scalability

scalable urban morphometrics

Idea of a morphotope

Take home points

Times have changed. Methods have changed. Concepts? Those only evolved

Urban morphology can be deeply embedded in spatial data science

Urban morphometrics can support quantitative studies done at scale

We can ask questions like never before
