I propose a Transparent unified Infrastructure Investment Platform, consisting of:
A. Unified City Infrastructure Data Hub (postgresql + postGIS)
A minimal, standards-based data integration layer that consolidates Tallinn’s core infrastructure datasets
1. Built using open source solutions for assets, geometry, maintenance logs etc.
2. Designed for extensibility toward future sectors (parks, mobility, utilities).
We intentionally avoid traditional GIS software (e.g., ArcGIS, proprietary tools) because these introduce:
1. high licensing costs
2. complex workflows
3. vendor lock-in
4. irrelevant features for Tallinn’s needs (and majority of the cities!)
B. Investment Prioritization Calculator
A transparent, multi-criteria scoring engine that evaluates proposed investment projects using:
1. location context
2. infrastructure condition
3. user numbers and demographics
4. risk, cost, and timing
5. alignment with policies and long-term plans
This directly fulfills Tallinn’s need for an objective scoring basis (as stated on page 2 of the challenge document: “a score based on all available information regarding the construction site and its surroundings”.
