Summary

This dataset is the output of a python script/ArcGIS model that identifes dikes as having a difference in elevation above a certain threshold. If the elevation difference was below a certain threshold the area was not considered a dike; however, if the difference in elevation between two points was significantly high then the area was marked as a dike. Areas continuous with eachother were considered part of the same dike. Post processing occured. Users examined the data output, comparing the proposed dike locations to aerial imagery, flowline data, and the DEM. Dikes that appeared to be false positives were deleted from the data set.

Purpose

The dike locations were collected because their identification is an important part of characterizing the physical attributes of the region. Since dikes were, historically, used to dry out wet areas for planting row crops and to prevent flooding, it is fruitful to examine where dikes may be removed as this could aid in restoring wetland-functionality to a given area.
