Service Description: Part of the digital collection "Cowling Arboretum Collection" hosted by Carleton College library, https://contentdm.carleton.edu/digital/collection/Arb/id/4212/rec/117.
The 1990 map of Carleton College Arboretum is georeferenced using mainly the Public Land Survey grid boundary and trail intersections with the spline transformation. Quality is assessed at the scale of 1:2,400 using trails (GIS line features, or 1999, 2000 or other aerial photos), highways (1999, 2000 or other aerial photos), and Arboretum planting units (GIS polygon features).
For uses that require accurate delineations of vegetation types, use the map with aerial photos taken around the same time.
The alignment outside Carleton College is poor.
