This book contains 200+ pages of never before published information detailing how to retrace a highway, road, easement or other controlling centerline. This book includes a new analysis method titled "Crume's Transformation" that was developed by the author based upon 25+ years of experience of performing highway centerline retracements. The trick to using Linear Regression for tangent line analysis and curve fitting is explained. Details are shown for integrating CADD, COGO, Google Earth, KMZ files to display survey information and setting up spreadsheet programs to perform the analysis.
