- •
Image interpretations of slums contain uncertainties which may negatively impact the accuracy of classification.
- •
We study deviations in slum identification and their delineations as observed from images of three cities.
- •
Existential and extensional uncertainties of slums are modelled in terms of random sets.
- •
Factors of the built environment that experts use to distinguish slums from non-slum areas are identified.
- •
Factors leading to deviations in slum identification and hence the reasons for uncertainties are explored.
