Service Description:
Part of the digital collection "Cowling Arboretum Collection" in the Carleton College library, https://contentdm.carleton.edu/digital/collection/Arb/id/4111/rec/58.

The 2012 Carleton College Arboretum map is georeferenced to the NAD 1983 UTM Zone 15N spatial reference in ArcMap 10.7.1 using mainly road intersections as control points with the first order (Affine) transformation. Total root-mean-square (RMS) error is 1.49 meters with individual residuals ranging 0.22 m - 2.37 m. Using Public Land Survey grids as control points was attempted but the result was poor.

This tile layer is re-projected to the spatial reference used by ArcGIS Online map viewer.

Quality of alignment was visually assessed using roads, railroads, trails and campus buildings visible on aerial photos at the scale of 1:2,400. Quality outside Carleton College property was not considered.
