About the Network
The National Trails System GIS Network was formed in 2011 and includes representatives from agencies that administer national trails as well as members of trail associations, scholars conducting trail research, and affiliates from educational institutions. Our mission is to connect the diverse array of staff and partners who use Geographic Information Systems (GIS) and mapping products in their work as well as to facilitate the sharing of information and tools that help us do our jobs more efficiently and innovatively. The network is open to all who are interested.
Monthly Webinar Series
Join fellow GIS Professionals and Trail Advocates from across the country on our monthly webinars hosted on the third Tuesday of each month.
Presentation: Matt Robinson, GIS Specialist, Appalachian National Scenic Trail
Update on National Trails System Web Map and 50th Anniversary Map
An update and discussion on the present National Trails System web mapping effort and 50th Anniversary Map. Please review the web map and be ready to discuss and provide feedback. The web map can be viewed at: https://nps.maps.arcgis.com/apps/webappviewer/index.html?id=d89951079a374f28ab4a3b9fc41025dd
Presentation: Rob Chohan, Mobile Architect, 𝘦π Maps
Creating Mobile-first Offline Maps using Authoritative Trails Data
𝘦π Maps are designed with mobile in mind from the beginning. “Mobile-first” means that the customers experience is great once they download the app. And if the application is backcountry or search and rescue, then the customer is ready to “go well prepared”. We build our maps using Authoritative Trails data from the US Forest Service and US Geologic Survey. We take care to use shaded relief and 40 foot contours from the USGS. We also adhere to the National Park Service iconography for a consistent experience. We will also discuss some of the image compression and data reduction techniques that we use to fit the entire map fits in the mobile app.

Producing Half Mile Scale Hiking Maps for the Continental Divide Trail
The CDTC has never produced a map set suitable for hiking the CDT that highlights the NST route. The existing 3rd party produced maps that have either a high cost to trail users or provided hiking information that is not always consistent with the intent or management direction of the CDT. Our goal was to produce a free community resource for the CDT using modern and authoritative data in a manner that was easy to maintain and update for the future.
Presentation: Brian Riordan, Customer Success Lead, Strava Metro
Big Data for Monitoring Trails and Recreation
This is presentation is an exploration of an app-based big data solution to see how groups have been using Strava to gain insights into bike/ped movements on trail networks. It looks at how big data is being used and why it is so key for this data to be used in new ways by groups with large regions of land and trail networks. We will dive into the growth of Strava, Geo functions around the company and how Strava Metro is being used now to monitor trail systems. We will also discuss the future of app technology and explore how to use the information to make the best planning and investment choices. Here is a chance to learn about a 5+ trillion point GPS database and get feedback to the top of Strava. Understand what is available now to help with mapping, editing, elevation and trail use.
Discussion: Sarah Quinn, External Renewable Energy Program Lead, National Park Service; Jill Jensen, Archaeologist, Old Spanish Trail, National Park Service
Balancing Public Data with Resource Protection
How can we create maps and provide data easily while protecting the resources of our National Trails? How can we best and responsibly represent trail resources? Join us for a discussion with representatives from the National Park Service’s Environmental Compliance, Renewable Energy, and Resource Protection on the benefits and risks of mapping and how better maps can lead to better resource conflict avoidance and protection.
Presentation: Chelsea Bodamer, Partnership for the National Trails Sytem
NPS ArcGIS Open Data
The Partnership for the National Trails System has recently developed a new online forum. Before its official release to the public, Chelsea would like to present the new interface, and open the discussion up for feedback and advice from the NTS GIS community.
Presentation: Paul Voris, National Park Service
NPS ArcGIS Open Data
NPS ArcGIS Open Data is a public facing website where data can be discovered and shared with users or referenced in IRMA and can be easily downloaded in a variety of formats. The site collects data from groups designated as Open Data within our organization and presents it to the public in an easy to use interface. The data can be used directly from a service such as a hosted feature service or map service or it can be downloaded as a Shapefiles, File GeoDatabases, or accessed through the GeoJSON API.
Presentation: Lisa Johnson, Boise State University
America’s Public Parks and Protected Areas: Introducing the Improved Protected Areas Database of the United States (PAD-US)
America’s tremendous asset base of protected areas is critical for conservation planning, natural resource management, outdoor recreation, public health and more. These include national parks and forests, wildlife sanctuaries, state beaches and parks, county open space, city parks, land trust preserves, conservation easements, marine protected areas and more. Altogether, over 3 billion acres (with overlapping designations) are managed by thousands of public agencies and non-proﬁt organizations that serve current and future generations. A complete and current database of these places is a critical tool to achieve organizational missions across jurisdictions. The 2016 PAD-US update (1.4), published by USGS, includes the best available geospatial representation of federal, state and other protected areas with descriptors like owner / manager name, designation type, unit name and other information useful for various applications. Join us to learn about America’s oﬃcial inventory of protected areas, applications, relationships to National Trails data, our strategy to complete the inventory by 2020, viewers, tools and opportunities to engage.
Discussion: Matthew Rowbotham, North Country Trail Association
Developing a Web Forum for National Trails System GIS
Topics for discussion may include: included content, strategies for implementation, web hosting, and a discussion of examples. Your participation is welcomed and encouraged!
Discussion: Peter Bonsall, National Park Service
Developing a comprehensive National Trails System GIS data layer and web map
In September, a concerted effort was made to aggregate a National Trails System GIS layer for use in Argon National Laboratory’s energy corridor assessment tool. As a result, all of the National Trails System data is now aggregated in one location. The next step is to discuss how we can come to a consensus and make a public GIS layer, especially in light of the National Trails System Act 50th Anniversary. Topics for discussion may include 1) Strategy for implementation; 2) FTDS attributes; 3) Hosting the data; and 4) How to address sensitivity issues.
Presentation: Ryan Abrahamsen, Terrain 360
Virtually Touring the National Trails – Providing 360° Imagery and Interactive Panoramic Maps along National Trails and Waterways
Terrain360 has been commissioned to map the waterways of the Captain John Smith National Scenic Trail. We will discuss our process, data management, challenges for large scale projects and ways to use and incorporate and disseminate this data. We will also discuss other projects including using machine learning object detection in our imagery, crowd sourcing imagery and GIS data for hiking trails and possible partnership with REI (adventure projects) to map National scenic trails and national parks.
