Maintaining Trail Data in Alaska Region Parks
After working with Trail Specialists and Facility Managers in Alaska parks, the Alaska Region GIS Team designed a regional Trail Spatial Data Standard in 2013 intended to streamline field data collection and work as seamlessly as possible with the NPS Facilities Management Software System (FMSS). In the six years since initial implementation, we’ve learned many lessons that have helped us make continual improvements to the design and workflows surrounding data collection and maintenance. Please join us to learn more about this journey.

Increase Access and Expand Recreational Opportunities on the Nation’s Public Lands by Connecting Trail Systems
Our Nation is home to a vast network of recreational trails traveled by millions of citizens. This trail network varies in age from hundreds of years old to brand new and varies in purpose from recreation to providing critical transportation routes. The trails also vary by managing organization. Because of this varied legacy, existing trails do not form a coherent, connected network. The overall objective of this project is to increase the connectivity within this network.

A new citizen science tool for mapping and monitoring the National Trail System with the GLOBE Observer mobile app
Citizen science is a great way to help trail users to connect with and learn about the environment while making useful contributions to science and land management. In this presentation, I will introduce the GLOBE Observer (GO) citizen science project and explore how it could be used for the mapping, measuring, and monitoring of the National Trail System.
What is GLOBE Observer (GO)?
With the free GLOBE Observer mobile app, recreationists use their smart phones to make observations with photos and text about the environment, wherever they find themselves. These data are geographically linked to satellite images and provide more details of Earth’s surface than we tend to get from satellites. They can compare their observations to those of others around the world. Importantly, land managers can use the submitted data to improve their own geospatial data, outreach activities, or engage new trail users. Scientists are using this data to improve maps of forest recovery after fires, tracking invasive species, and monitoring trail conditions.
The Global Learning and Observations to Benefit the Environment (GLOBE) Program is an international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment. It is sponsored by the U.S. National Aeronautics and Space Administration (NASA) with support from the National Science Foundation (NSF), National Oceanic and Atmospheric Administration (NOAA) and Department of State. . The app is free from the App Store and Google Play. Once downloaded, data can be collected while offline. https://observer.globe.gov/

Applications of Unmanned Aircraft Systems (UAS), Photogrammetrics, and Machine Learning to Record Archaeological Sites and Historic Trails.
Archaeologists have two goals, to record known sites and locate new ones. In 2018, the Boise National Forest began thinking outside the box to accomplish these objectives. We signed an agreement with Northwest Nazarene University (NNU) to begin using Unmanned Aircraft Systems (UAS or drones) to record and find archaeological sites. Over the summer of 2018, we recorded over 2,000 acres of National Forest Land with a UAS. While most of the work was done on historic mining sites, we also recorded small sections of historic railroad grade. Sections of the Oregon Trail were recorded in 2017. In addition to recording sites, undergraduate students at NNU have developed Machine Learning algorithms to locate archaeological artifacts and features. One of these algorithms can locate historic metal fragments (cans, stoves, sheet metal, etc.), and another can locate linear features, such as roads and trails. The techniques of UAS data collection and Machine Learning algorithms, being developed by NNU and the Boise National Forest, will help federal agencies and private organizations locate, record, and manage archaeological sites and historic trails. Our presentation focuses on the genesis of this partnership, methods for data collection, and the results.

Creating an Authoritative Data Source for the Arizona National Scenic Trail
This presentation will share the strategy developed under an Esri EAP agreement to create an authoritative data source for the entire AZ National Scenic Trail: its geography and associated attributes. The workflow will allow partner agencies to submit proposed alignment changes via ArcGIS Server Feature Services. Data governance is to be provided by USDA Forest Service Region 3 data stewards as described in the Arizona National Scenic Trail Alignment Data Governance. Follow-up discussion reiterated Esri’s finding, “Although this geodatabase environment and workflows were designed for the AZNST alignment in mind, they could generally be used for any national trail. Standardizing the ways proposed updates are sent to the managing agency and the workflows that include data governance could be useful for other national trails or other kinds of projects where GIS data updates come from multiple sources.” Sharing the authoritative data is to be accomplished via a map service in ArcGIS Server with download capability enabled.

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.

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.
