Park Tiles

2016–current. Vector web map published using Mapbox Atlas. Data compiled in QGIS and PostgreSQL/PostGIS.

Park Tiles is the general-use, visitor-oriented web basemap for the National Park Service, and is used in a number of maps on Example live versions can be viewed on the NPS maps page, the Yellowstone Live Roads map, and Golden Gate NRA, among many others. Read more about Park Tiles and the closely-linked tools my team develops and maintains to bring web maps to the National Park Service website.

Yellowstone Live

The Yellowstone Live project is comprised of a series of wall monitors, interactive kiosks, and web maps that convey current conditions at the park to visitors. An initial version had been in operation for a couple of years when, in the spring of 2017, park staff determined that some of the colors used in the application might not be accessible to color-blind viewers. In addition, colors selected to convey "open" vs. "closed" were not used in a consistent way across the various displays. Specifically for the road status map, park staff also requested a unified set of road symbols that would elimniate the need to toggle different map states with radio buttons. I assessed current conditions using the Color Oracle simulator and developed alternative color and map symbols schemes, which I helped implement in the code base once designs were finalized. I adapted the slide deck above from my presentations to park staff and the project team. Use these links to access the live maps for roads and campgrounds.

NPS System Map

2018. Adobe Illustrator/Avenza MAPublisher. Data compiled in QGIS, including raster data manipulation.

In 2017, I took over management of my division's comprehensive map of all National Park Service units, regions, affiliated sites, national trails, national rivers, and national heritage areas. In doing so, I shifted the workflow over to MAPublisher to give me greater flexibility for cartographic symbolization and overall layout design.

In 2021, a version of this map was included in Mapping America's National Parks, published by Esri Press.
