Crater Lake National Park


Digital maps for the National Park Service


We maintain a set of tools that are custom-built to address the National Park Service's web mapping needs. This toolset evolves as new technologies are integrated and old technologies are phased out.

We know these tools work because we use them everyday in our own projects. They help us build accessible, usable, and stable maps that fit into the rich graphic tradition of the National Park Service. They also help ensure longevity for our maps, as building maps with a set of consistent and tried-and-tested tools means we aren't building one-offs that require individual attention and maintenance. Because of this, maps built with our tools today will continue to improve as our toolset improves.

Anyone in the National Park Service can use our tools. They support a wide variety of platforms and technologies, and are extremely flexible and powerful. If you are new to web maping, you'll probably want to get started with the NPMap Builder. It wraps our standalone tools in a graphical interface that walks you through the process of building and deploying a web map step-by-step. If, however, you are a developer or are more technically-inclined, you can use our tools individually to jumpstart your project.
