How this is built
Every number on a place page should be traceable to a free public source.
Coordinates and town attributes come first from the GeoNames cities5000 gazetteer (CC BY 4.0). If a place is too small to appear there, the builder asks the Wikipedia REST summary API for the coordinates published on that article, and the page says so.
Airports come from OurAirports airports.csv (public domain). The page names the nearest large or medium airport that has scheduled service and an IATA code, within 250 km, using a great-circle distance.
Named ports come from Natural Earth 10m ports (public domain). A port is shown only if it is within 60 km.
Monthly weather is a 2024 snapshot: daily mean air temperature and daily precipitation from the Open-Meteo Historical Weather API, summed or averaged by calendar month. That is one year of weather, not a 30-year climate normal, and it is air temperature, not water temperature.
The NGA World Port Index would add harbour depths and shelter. The official download at msi.nga.mil returned HTTP 503 on two attempts on 12 Nov 2026, so it is not in this version.
Booking links point at public marketplace destination or search URLs. Affiliate tracking IDs will be added only after a programme accepts the site. Until then the buttons are labelled as not affiliate links.
Pages are generated as static HTML. There is no user account, no server-side database, and no live price scrape.
