This file is a projection definition document associated with a rare plant survey project for the Minnesota Department of Natural Resources (MN DNR) Parks & Trails Division. The document defines the geographic coordinate system and mapping parameters used for the Arrowhead State Trail project, specifically establishing NAD 1983 UTM Zone 15N as the spatial reference framework. The file utilizes Transverse Mercator projection with a central meridian of -93 degrees longitude and is calibrated for measurements in meters, indicating it serves as a technical specification for geospatial data collection and analysis related to the survey area.

The underlying project involves a rare plant survey along a 6.2-mile corridor of a proposed Arrowhead State Trail re-route managed by the Tower Area. The survey area extends 50 feet from the trail centerline on both sides and encompasses mixed habitat types including constructed trail and road areas, clear-cut forests, regenerating clear-cut areas, and mixed deciduous and coniferous forests. This survey is designed to identify any rare plant species present prior to the trail's re-routing and upgrading for all-season all-terrain vehicle use. The coordinate system definition provided in this file ensures that all survey data, mapping deliverables, and spatial analysis for the project maintain consistency and accuracy across the designated corridor in Minnesota.
