Figure 3. Comparison of the structure contour maps on the base of the Mfp generated using two methods of data collection for the area in the southern Nashville dome. These maps were constructed using identical parameters with the exception of the data collection methods across an area of 32 quadrangles [6-37]): (a) was constructed by manually picking ~4,000 data points (gray circles) and (b) was generated from ~82,000 auto-picked points (gray dots that appear as a dendritic pattern along outcrop surfaces, the density of points were too high to display correctly at this resolution) using the methods developed during this study. These maps appear very similar regionally, but many more sub-quadrangle-scale features are visible in the higher-resolution auto-picked map that are not present in the lower-resolution manually picked map. The white areas indicate areas where no outcrops for this contact occur.
