Service Description: Source Dakota County and Goodhue County map images are downloaded from the collection "David Rumsey Historical Map Collection" at David Rumsey Map Collection site. 

Dakota County map:
Source - Map of Dakota County, Minn. Alfred Theodore Andreas.  A.T. Andreas, Lakeside Building, Chicago, 1874.
Scale -  1:150,000. 
Georeferencing - 2nd order polynomial transformation using mainly county and township boundary intersections as control points. Total RMS Error 63.5 meters, with individual residuals ranging 15 m - 120.9 m. Larger residuals are a result of control points along Dakota and Goodhue county boundary for more seamless alignment of the two county maps.

Goodhue County map
Source - Map of Goodhue County, Minn. Alfred Theodore Andreas.  A.T. Andreas, Lakeside Building, Chicago, 1874.
Scale - 1:170,000. 
Georeferencing - 2nd order polynomial transformation using mainly county and township boundary intersections as control points. Total RMS Error 35.4 meters, with individual residuals ranging 5.3 m - 59.2 m.
