This is a project file containing geospatial coordinate system information for the Arrowhead State Trail (AST) Ash River Trail Reroute Wetlands project, supporting a rare plant survey contract opportunity with the Minnesota Department of Natural Resources (MN DNR) Parks & Trails Division. The project involves surveying a 6.2-mile corridor along a proposed re-route of the Arrowhead State Trail in the Tower Area to identify rare plant species before trail construction and surface upgrades for all-season ATV use. The survey area extends 50 feet from the trail centerline on both sides and encompasses a mixed landscape of constructed trail/road areas, clear cut forests, clear cut re-growth, and mixed deciduous/coniferous forest. The file itself is a projection file using NAD 1983 UTM Zone 15N coordinate system parameters, which defines the geographic reference framework for mapping and spatial analysis of the survey area.

The projection file establishes the technical specifications necessary for accurate geospatial data collection and analysis within the project area, utilizing standard North American cartographic parameters with transverse Mercator projection centered at -93 degrees longitude. This coordinate system ensures consistency across survey data and environmental assessments required for the trail reroute planning and rare species protection compliance.
