Viewing Program Locations in Rocky Mountain National Park, Colorado

We just released a new version of the state page maps for each of the NPS.gov state pages. These maps are intended to demonstrate the breadth of the impact the National Park Service has on communities across America. They include National Parks as well as locations from various NPS programs like the National Register of Historic Places, Federal Lands to Parks, the Rivers, Trails, and Conservation Assistance Program, and more.

Park Tiles

The previous version of the state page maps used out-of-the-box Bing tiles. The maps now use our custom basemap, Park Tiles. The design of Park Tiles pushes National Park unit boundaries and program locations to the forefront of the map.

About the Technology

NPMap.js is built on top of Leaflet and uses the Leaflet.markercluster plugin internally to support marker clustering. This makes it possible to display the more than 100,000+ program locations across the country while maintaining good performance across all platforms and browsers.

The point data for each of the maps is stored and served directly from GitHub using GitHub Pages.

Take a Look

You can access the state pages directly from the NPS.gov home page. Simply select a state from the dropdown at the top right-hand corner of the page.
