WP7·Dissemination and open science documentation

Open sources, stated limits.

The protocol commits to open access, FAIR data and a public story map. This site is a small version of the last; here is what it rests on.

What is shared

Shared here

  • Model observations per view, street segment and buurt, with the model and revision behind them.
  • The tables behind every figure, and the search index.
  • Code: GeoAI-VLM, open source.

Not shared, or only linked

  • Street images load from the City's own server. Hosted here, with attribution: one example panorama with its four views (WP3), the 47 before/after pairs (WP6) and an aerial poster (home).
  • No personal data: mobility is synthetic throughout; the City blurs people and plates before publishing panoramas.
  • No model weights are redistributed.
  • Survey answers (pilot): anonymous, in a PostgreSQL database (Supabase, EU) that visitors can only add to; published as totals only, never as rows.

Details
Provenance record
Known limits of the street-level data
  • One year (2025), on days the City's car drove, in summer daylight, seen from the carriageway.
  • Footways and paths are rarely recorded (8% of their length).
  • View direction follows the estimated driving direction, which can be some degrees off on sharp turns.
  • Model output is not measurement: each feature carries its agreement with a larger model, and three are not used (WP3).
