Where the data comes from

The geometry (coastline, provinces, rivers, Caminos, municipal boundaries) and much of the catalogue come from OpenStreetMap. The licence is ODbL, which requires two things: to credit —the map carries the attribution visibly— and, if a derived database, publish it under the same licence.

That does not prevent charging for a service built on top, and it does not force opening the site's code either: what is shared is the derived database, not the program. Worth being clear about before signing anything.

Names, coordinates, types, dates and the names in other languages. CC0 is public domain: no obligations. It is the most convenient source and that is why it is the basis of the catalogue.

The texts of the entries. It requires to credit and to keep the same licence in the reused text. Each entry says so at the foot, with the language of the article.

It is the most demanding source: if closed content were ever to be sold, the texts would have to be rewritten or replaced. The rest of the project is unaffected.

The photos. Each image has its own licence —usually CC BY-SA— and its author: under every photo you will find the name of whoever took it, the licence and the link to the original file on Commons. No copies are served: everything points to the original file.

Satellite heat spots (NASA, public domain) and cetacean records (GBIF and iNaturalist, open licences per record). They are live data and are not stored: they are queried and they expire.

The «Today» tab reads the open RSS front pages of Nós Diario, GCiencia, Faro de Vigo, La Región, El Correo Gallego, Diario de Pontevedra, El Progreso, La Opinión da Coruña, Atlántico Diario and Economía Digital Galicia. Only the headline and the outlet are shown, and the link always goes to the newspaper: no story is reproduced here and no text is stored.

The weather and the state of the sea —temperature, sky, wind, wave height, water temperature, sunrise and sunset—, licensed CC BY 4.0. It is queried live and not stored.

The symbol marking the Camino on the map is by Marco Perez Kistler (CC BY-SA 4.0), drawn from the official description published in the Diario Oficial de Galicia. It is not the work of this project.

The taxonomy of 16 categories and 84 types, the engraved icons, the tourist regions, the fame measure drawn from Wikipedia visits, the trip plans and the software itself. That is original work and comes from no outside source.

A today's aerial view is the most up-to-date PNOA from the IGN: 25 centimetres per pixel over most of Galicia. Underneath it lies the worldwide mosaic Sentinel-2 cloudless by EOX (CC BY 4.0), which covers what the PNOA does not reach —Portugal, the sea— so that there are no gaps.

Both are served from their own servers, with the attribution visible on the map. They are neither downloaded nor rehosted.

The view of Galicia in 1956 are the orthophotos of the American Series B survey, which the United States Army Map Service flew over Spain between 1956 and 1957 and which the IGN publishes openly through its historical PNOA service. They are served straight from its servers, with the attribution visible on the map.

They are neither downloaded nor rehosted: if the IGN changes or withdraws the service, this view stops working, and that is as it should be.
