OpenTrails Tools

Create open data for your region's trail system, ready for use across the web.

This tool is incomplete and under active development. Learn More on Github.

Help is Available

When you begin the process of converting or validating your data, we will create a unique URL. If you run into any issues, you can revisit that URL, or share it with your colleagues.

Moreoever, the Code for America team is available to provide assistance if you run into any problems. Once you begin the conversion process, a feedback form will appear in the bottom-right hand side of your screen.

About OpenTrails

The Open Trail System Specification (OpenTrails) provides a uniform “exchange format” for publishing machine readable data on the extent, attributes, and use of our nation’s trail systems.

OpenTrails is designed for park agencies that want to get reliable trail maps into the hands of their visitors. OpenTrails data is ideal for use on agency websites, in mobile apps, and for consumption by third-parties that offer trail maps in many locations. OpenTrails is GeoJSON and CSV open data format ideal for web and mobile applications.

You can learn more about OpenTrails, its primary use-cases, the ecosystem of services, and more on the OpenTrails home page.

Shapefiles > OpenTrails

OpenTrails is designed with park and public land manager in mind. The vast majority of park and trail stewards in the United States use GIS tools from ESRI. Many park agencies maintain their data in the PRORAGIS model, promoted by the National Recreation and Parks Association, that relies on ESRI file formats. As a result, the converter tool is designed to accept GIS data maintained in shapefile formats.

We'd like to thank ESRI, the NRPA and PAD-US and many others for their critical advisory role in the development of the OpenTrails specification, and their support for these tools.

We're Under Construction!

Currently, the tool only supports conversion of trail segment data, i.e. the polyline features that describe the alignment of trails.

Ultimately, OpenTrails consists of the following files:

Functionality for converting shapefiles representing both trailheads (points) and areas (boundary polygons) is forthcoming.
