Sources and licences

Each layer keeps its source's licence; our code is MIT; our own compilations are CC BY 4.0. This page is generated from the metadata of the published layers (7 data sources), so it cannot differ from the data.

Base map

The background map is drawn from vector tiles served by OpenFreeMap, built from OpenMapTiles with data from OpenStreetMap contributors (ODbL). The map style is our own. It carries no administrative boundaries: borders on the map come only from the boundary set above.

Boundaries and points of view

Boundaries follow the US government's point of view and do not express a position of the project. Areas that belong to no country in this view are drawn with a neutral fill.
