Fonti dei dati
Ultimo aggiornamento: 25 ottobre 2026
1. In breve
La maggior parte delle palestre su GYM3 viene da OpenStreetMap. Per alcune sale delle grandi città in Francia, Spagna, Italia e Tunisia, nome e posizione vengono da altre fonti aperte: Overture Maps, Foursquare OS Places, il censimento francese degli impianti sportivi (Data ES) e gli open data di alcuni comuni e regioni.
La pagina di una sala presa da queste fonti, o da OpenStreetMap, dice da quali viene, con il credito e la licenza che ogni fonte chiede. Qui sotto ci sono tutte, con il testo delle licenze dove la licenza lo chiede.
Una sala presa da queste altre fonti entra solo se la danno almeno due fonti indipendenti, o se l’abbiamo controllata a mano sul suo sito.
Nessuna di queste fonti è legata a GYM3, e nessuna approva il nostro servizio. Se trovi una sala sbagliata o chiusa, scrivici a ciao@gym3.app.
2. OpenStreetMap
Nomi e posizioni della maggior parte delle sale vengono da OpenStreetMap, la mappa libera fatta da chi la usa. Da OpenStreetMap vengono anche i confini di comuni e quartieri e, dove ci sono, via, orari e sito della sala.
© i contributori di OpenStreetMap. I dati sono disponibili con la Open Database License (ODbL) 1.0. Credito e condizioni: openstreetmap.org/copyright.
3. Overture Maps
Per alcune sale nome e posizione vengono da Overture Maps Places, release 2026-10-21.0, della Overture Maps Foundation. Il credito che Overture suggerisce: «Overture Maps Foundation, overturemaps.org».
In Overture ogni luogo porta la licenza della fonte da cui arriva. Nelle sale di GYM3 ci sono queste, come le scrive la pagina delle licenze di Overture:
- Data from Meta, Data from Microsoft, Data from BrightQuery: CDLA Permissive 2.0.
- Data from Foursquare: Copyright 2024 Foursquare Labs, Inc. All rights reserved. Apache 2.0. Overture aggiunge: «Foursquare data was transformed to the Overture schema. Changed: 2026-03-18.», con il link all’avviso di Foursquare (NOTICE.txt). Il testo della licenza e l’avviso della release del 2025 sono nella sezione 4.
- Data from AllThePlaces: CC0 1.0. Da sola non fa mai entrare una sala.
La CDLA Permissive 2.0 chiede a chi condivide i dati di metterne a disposizione il testo: eccolo.

4. Foursquare OS Places
Per alcune sale nome e posizione vengono da Foursquare OS Places, la release del 6 febbraio 2025. © 2025 Foursquare Labs, Inc. All rights reserved. I dati sono disponibili con la Apache License 2.0.
La licenza chiede tre cose a chi usa e modifica i dati: dare il testo della licenza, dare l’avviso di Foursquare per intero e dire cosa è stato cambiato. Sono qui sotto, e anche come file: LICENSE.txt e NOTICE.txt.
Cosa abbiamo cambiato
- abbiamo preso solo i luoghi di sport di 26 grandi città, e dei comuni vicini, in Francia, Spagna, Italia e Tunisia;
- abbiamo tenuto solo le palestre dove ci si allena coi pesi, e solo se un’altra fonte indipendente conferma la sala o se l’abbiamo controllata a mano sul suo sito;
- abbiamo unito i dati di Foursquare a quelli delle altre fonti di questa pagina: nome e posizione di una sala possono venire da una fonte diversa;
- abbiamo aggiunto il comune, dai confini di OpenStreetMap, e a volte il quartiere;
- dove due fonti recenti dicono che la sala ha cambiato nome, abbiamo scritto quello di oggi;
- abbiamo lasciato fuori gli altri campi di Foursquare: sul sito ci sono solo il nome e la posizione della sala.
Le modifiche sono del 25 ottobre 2026.

5. Data ES, il censimento francese
Per alcune sale in Francia nome e posizione vengono da Data ES, il censimento degli impianti sportivi del Ministère des Sports (equipements.sports.gouv.fr). Fonte: Ministère des Sports, Data ES, aggiornamento del 25 ottobre 2026.
I dati sono disponibili con la Licence Ouverte 2.0 (Etalab). Ne abbiamo preso solo alcuni tipi di sala (muscolazione, pesistica, boxe, corsi), e li abbiamo uniti alle altre fonti.
6. Open data dei comuni e delle regioni
Per alcune sale in Spagna e a Milano, nome e posizione vengono dagli elenchi aperti delle amministrazioni. Da ogni elenco abbiamo preso solo le voci di palestra o di sala pesi, e le abbiamo unite alle altre fonti: non sono gli elenchi completi.
