How this map is made

For civic points, OpenStreetMap features and public infrastructure, we follow two rules. Things that break: water points, toilets: are published only with the date someone went and checked, and with the name of whoever did when the source states it: today that is always an OpenStreetMap or fontanelle.org mapper, never us. Of 171 water points and toilets, 94 carry a name, and some of those dates are years old. We show the date rather than hide it. Stable things: a square, a bridge, a façade: are published once the source has been checked, and the source is named; they carry no author, because reading a database is not a walk. For curated professional profiles, a third rule applies: we verify professional details in official sources, with source and date shown; an on-site check is not required, and these details remain separate from OpenStreetMap/ODbL.

📋What’s published right now

• acqua: 109, plus 13 reported broken — on the map, struck through, at the bottom
• bagno: 41
• studio: 60
• vedere: 229
• utile: 582
• parco: 63

Checked by OpenStreetMap mappers and the fontanelle.org community (2010-07-22 → 2026-07-17). 94 points out of 1097 carry one.

Two routes, the same neutrality

There are two separate routes. A host point enters the map only when it offers a real free service with no obligation to buy. Curated professional profiles in “I need” may instead describe paid services: they use details read from official sources and remain separate from the OpenStreetMap/ODbL dataset. In both cases, presence and order cannot be bought: payments, partnerships, contacts and profile completeness give no priority.

Free host points appear in the same list as every other map point. The list is ordered by distance from your position when you give it to us, and from the city centre when we do not know it; then points whose check is more than three years old sink below fresh alternatives nearby, and points reported broken go last.

Local services and corrections

Local-service profiles use professional details read from official sources, with source and date shown; they are not part of the OpenStreetMap dataset. We publish a contact only when its source presents it for professional use. You can suggest a correction without giving a name, account, contact detail or free text: the server creates a daily pseudonymous HMAC code, deleted within 90 days. The report remains an operational fact until it is checked and never changes a profile automatically.

Weather and official sources

The situation strip is not a map layer and does not use your location. Our server asks for the fixed Pisa city-centre coordinates: MET Norway for the forecast, CFR Toscana for official weather and hydrogeological alerts in area A6, and INGV for seismic events that have already occurred.

MET Norway data is credited under CC BY 4.0. Every source keeps its official link and timestamp. If a source is stale, incomplete or unreachable, it is shown separately as “Source cannot be verified right now”: the guide does not turn an unknown state into “no alert”. INGV does not predict earthquakes, and perdiqua does not present its event catalogue as a forecast.

🚫What we don’t do

• No ratings, no rankings, no stars. We say what was there, and when.
• No cookies, no third-party trackers, no sign-up, no email collection.
• No third-party prices. Where a line says something costs, it says only that, never how much: a figure goes stale on its own. One exception, and it is declared: public transport fines, because they are set by a public act rather than by a business, and the operator publishes them in its service charter — which we link next to them. We don’t write opening hours either: we show OpenStreetMap’s, named as theirs, with the caveat next to them — and where the syntax isn’t readable we don’t say whether it’s open.

🔄What we give back

The point data comes from OpenStreetMap under the ODbL licence. A field correction becomes ours only after a real visit; once checked, our method is to publish it there with its date. Source checks and fieldwork remain visibly separate.

🌙When this map switches itself off

The most likely way a project like this dies is not a mistake: it is staying online after it is over. That is why every point carries the date of its check in plain sight, and the oldest ones sink to the bottom of the list instead of sitting at the top: if this map ages, you can see it, point by point.

Corrections already published on OpenStreetMap remain there with their dates if the project closes. Reusable public work that has actually been returned does not disappear with the guide.
