This layer represents contour elevation lines as of the spring of 2017. The contours are derived from LiDAR data, collected in the winter of 2017/2018. Contours were generated using Global Mapper, sample spacing used to create the contours is consistent with the Nominal Point Spacing (NPS), of the source LiDAR dataset from which it was derived. Lines were automatically smoothed while being generated by Global Mapper.
