Data sources & licences
ShowMeOnMap never fabricates or pre-loads values — every number and coordinate on a map is fetched live from one of the sources below, and each map carries its own citation. This page is generated from the same registry the app and its automated health checks read, so it cannot drift out of date independently of the code.
75 of 98 sources have had their licence terms read and recorded. The rest are marked licence review pending — they are listed rather than hidden.
If you own one of these datasets and believe ShowMeOnMap is using it outside your terms, email franklan010@gmail.com and we will remove or license it.
