NPMap can consume base map tiles from many different sources, although not all of these tilesets are available under an existing National Park Service license agreement. The table below lists some of the base maps supported by NPMap and includes information on whether National Park Service users can legally access tiles served from the different vendors.
This list changes as projects fund access to new services and support for providers is added to the library, so please check back here regularly to ensure compliance with current NPS policies. You can also subscribe to our blog's feed or our mailing list to keep up-to-date.
