  6. Questions about these credits

The maps and aerial imagery in Gartenkern are not ours. They come from the German state survey offices, from Austria and Switzerland, from the federal government and from open mapping projects, and every one of those sources requires being named. This page names them.

It complements the privacy policy, which says which of these services your browser contacts and what is transmitted in the process. This page is only about where the data comes from.

What these credits cover

A source notice belongs to the data, not to the tile you happen to be looking at. When you trace your plot over an aerial image in the garden editor, the result is an adaptation of that data. The licences tie the duty of attribution to exactly that (Data licence Germany attribution 2.0, § 2 paragraph 3; Creative Commons BY 4.0, § 3 a 1 B).

The credits therefore travel with your layout wherever it goes: the editor, the garden view, PDF and image exports, a publicly shared garden, and every screenshot taken from it. If you pass your layout on, pass the matching notice from the table below along with it.

Where the aerial imagery comes from

One service per row, with the three pieces the licences ask for: the provider in the spelling it prescribes for itself, the licence with a link to its text, and the way to the dataset. The table is generated from the same provider list the map uses to fetch its tiles. What you read here is what is actually loaded.

The boundaries in the last two rows are not something you see as a picture. They decide, behind the scenes, which service your map asks, and are shipped to every browser for that purpose. Used means named, even for a file nobody looks at.

Base map and address search

The street map underneath the aerial imagery, and in every other map, comes from OpenFreeMap, a freely operated tile service (openfreemap.org). The geodata behind it comes from OpenStreetMap and its contributors, published under the Open Database License (ODbL). The notice for it reads: © OpenStreetMap contributors.

The address search works on the same data, through Komoot's open geocoder Photon. The outlines of allotment sites in the club finder also come from OpenStreetMap; they carry their notice on the map that shows them.

If the map shows no aerial imagery

All sixteen federal states appear in the table above, plus Austria and Switzerland. If your garden sits in another country, there is no official service for it in our list, and the street map stays in place. That is not a fault in your view.

Photos in the demo garden

The demo garden that every new garden account receives shows photos from Wikimedia Commons. They are under free licences or in the public domain. We scaled them down and recompressed them, otherwise unchanged. Who took them and under which licence:
