Worli Koliwada is a Koli fishing village on the Worli headland in Mumbai: 35.5 ha and 2,857 buildings. The project started as a 2018 urban planning studio at the Technical University of Crete and returns in 2026 as an urban informatics study of ten analysis boards and six proposal boards.

Synthesis. Six open datasets, resampled to a 100 m grid, produce nine built-environment metrics: Landsat 8 surface temperature, Sentinel-2 canopy, Copernicus terrain, and OpenStreetMap streets, buildings and services. Heat, access, flood exposure and crowding read together cell by cell. 12 of the 15 highest-need cells lie inside Koliwada, and the combined need averages 0.55 in the village against 0.21 in the 1 km ring around it.

Decision support. Each metric links to a municipal need and to the design move that answers it. The site averages 39.9 °C surface temperature, so the proposal plants 331 trees and 5.2 ha of green. Only 34 % of homes reach a clinic within a 10 minute walk; the proposal places services so every home sits inside a service radius. Against an 18 m² median building footprint, three block typologies give 12.7 m² per person on average, and 1.1 ha stays as working ground for the fishing economy.

Evaluation. The same metrics run again on the 2018 masterplan, registered to OpenStreetMap. Public green space grows from 4 % to 15 % of the site, vegetated cover from 5.4 % to 16.4 %, and homes within 400 m of a school, clinic or public use from 34 % to 100 %. Built coverage drops from 31 % to 23 %, freeing ground for public space. Homes within 300 m of green fall from 100 % to 90 %, and metro access stays at 0 %: it needs an off-site walking route and a feeder service.
