Idaho Recreation Trails

Hosted Feature Service The heart of the Idaho Trails Experience web app is the geographic data served by the Idaho Recreation Trails collection of Hosted Feature Layers. The Hosted service can be updated more frequently and on-the-fly than the previous technology used to maintain Idaho Trails-- changes now appear on the App and through the Feature Service in real time. The newest web presentation technology under AGOL, Experience Builder, served by this dataset, will make possible several extended features in the Web App. Under the hood Linear routes, closure routes and areas, and boundary area Hosted Feature Layers can be directly consumed from the Service via REST and are the source of features displayed in the Idaho Trails Web App. In addition to view settings for attributes popups set in the Web Map, additional visibility option not managed directly in the Hosted Feature data or controllable in the Web Map are further processed in the Idaho Trails Experience App presentation. Underlying Classes in the Idaho Recreation Trails dataset: One single linear class "Idaho Routes" contains all road and trail features (57,000+ route segment features): Routes characterized as recreational in nature include: High-clearance (previously "Jeep" treated as a road type, now as a full-width "trail" type), Special Vehicle Designation (mostly OHVs >50"), OHVs 50" and under, and single-track motorized (each width class separated by open year-long and motorized-seasonal); E-Bike (Class noted in Narrative); and, non-motorized and non-mechanized trails. Routes where vehicles either must be highway-legal (i.e., OHVs prohibited, typically paved roads), or routes requiring Restricted plate for legal OHV travel (mostly JURISDICTION = County); combined from previously-separate Layers: Highway-legal, Automobile, Other Roads (each with subcategories for seasonal access restrictions). (Note: Different route types are no longer kept in separate layers as with the legacy Map Service dataset. Route symbology, and selectable visibility is filtered based on the value in the SYMBOL attribute from the above linear class within the Web Map and Experience App. If dynamically consuming the Feature Service (REST), provisions will need to be made to filter to select visibility by road and trail types based on the value in the attribute field SYMBOL.) "Points of Interest" (point type data) is comprised of a layer previously titled "Trailheads" and now includes the flexibility of other types of lat/lon point-based information such as links to external maps and "attractions" information such as site seeing destinations not previously included in IDPR's map presentation. "Emergency Route Closures" contains linear route Closures (overlays any route where a Closure Order applies in web map) "Area Restrictions" is added for areas such as defined by human exclusion Orders (polygon; usually planned annual human or vehicle exclusion areas, but can be emergency closure such as for wildfires as well) Multiple "Boundary" polygon classes contain boundary outlines and attributes information for IDPR Regions (3), Counties (44), Wildernesses (42), National Forests and Ranger Districts (39), and BLM District and Field Offices (12), and BLM land units (700+). These separate classes reduce the data footprint of the Routes data and are joined in App popups by geographic Intersection logic. Bonus Material: Added to the web app are several optional, dynamic layers via publicly-available REST services selectable for visibility: NIFC Current and Historic Fire primeters Idaho Department of Lands- Lands Available for Recreational Use (visible by-default) Idaho Department of Fish & Game Hunting Units boundaries and numbers BLM Surface Management Agency layer for all local, state, and federal agencies which manage public lands (accessible, and not) US Forest Service Motor Vehicle Use Map, National Dataset (mirrors local MVUM paper and GeoPDF maps, where data available, lags local data when changes are made) National Park Service (NPS) Parks and Monuments areas and boundaries NOHRSC Snow Depth Other REST Services to be added based on utility in researching recreational access This dataset is published for the use of the individuals who fund this Program. Organizations wishing to consume this Feature Service into their own application should inquire to IDPR to obtain a use agreement and schema information to aid in development.
