Background
This trail database system was started in late 2018 as a unique feature of the original Wild West Jeep Club website. The goal was to provide easily accessible trail data for Nevada and surrounding states, specifically for those trails frequently run by the club.
Over the years, it has become somewhat of a hobby of mine, and has evolved beyond what I originally planned for it. It's become a highly interactive, community driven resource for the western US offroad community.
Following the dissolution of the club in early 2024, I decided to re-home the entire database and all its features to its own domain, thus the creation of Wild West Offroad Trails, a name that's familiar to those who have enjoyed its use before, and intriguing to those who are finding it for the first time.
Tech Info
Mapping & Geocoding Services
All interactive maps and static map images on this website are provided by Mapbox (www.mapbox.com) using their GL JS and Static Images APIs.
Geocoding services (used to convert geographic coordinates into a human-readable address or location description) provided by a combination of Positionstack (www.positionstack.com) and Mapbox Geocoder APIs.
Weather
Weather data is retrieved using APIs from either the National Weather Service (www.weather.gov) -OR- OpenWeather (www.openweathermap.org).
Visual Graphs
Visual graphs are generated using a non-commericial license of CanvasJS (www.canvasjs.com).
GPX Upload Processing
When a GPX file is uploaded to this site, onboard custom scripts scan the file for validity, then iterate through the waypoints and track/route segments, extracting necessary data, which is then stored in geoJSON format in a database. The original uploaded file is stored for diagnostic purposes, but not used again by the system.
Elevation Data
During upload processing, each GPX file track or route point is checked for elevation data. If an elevation value is missing from a location point, it is added automatically using lookups from onboard data from NASA's Shuttle Radar Topography Mission (SRTM). Currently, I am using SRTM data with a resolution of 3 arc seconds (about 90 meters). I plan to update this to a higher resolution, starting with the more mountainous areas.
Static Track Previews and Thumbnails
Thumbnails/track previews are generated using slimmed down versions of the full track. Mapbox's Static Images API has a maximum query length. First, the coordinate point array is run through a script to delete every other array element until the array contains less than 1,000 coordinate points. Then, the array is converted to a Google Maps Encoded Polyline, then URL encoded and passed to the API to generate the map image with the track overlay.
File Downloads
When a user downloads a file for a trail, internal scripts dynamically create the file from the database each time a download is requested. This ensures that the user is getting the absolute latest data. The scripts construct files in compliance with the GPS Exchange Format, Keyhole Markup Language XML and GeoJSON RFC 7946 schemas.
Water Flow Data
As of June 28, 2024, we are experimenting with capturing and storing water flow rates for rivers/streams that intersect or closely parallel the trails. The way this works right now is every hour, on the hour, data is downloaded from DreamFlows (www.dreamflows.com) for target rivers and stored in our database. There is a historical graph on some of the trail info pages with associated flow rate data that can be interacted with.** This is experimental. The methods we use to capture data may change as this evolves. Right now, we are only pulling data that is updated twice per hour, and in some cases, not at night.
