The resulting four maps can be compared to find patterns of human activity that occur around coastlines of Oahu and Kauai. The maps take into consideration the frequency of human activity/development on the islands as well as the magnitude to which these occurrences would affect the coast. Oahu has a higher population and more urban areas than Kauai which would insinuate that Oahu is at greater risk for coastal erosion caused by human variables. These maps may give insight as to whether this assumption would hold true. Some activities/development, such as dams, which occur more frequently on Kauai may be more impactful to coasts than other activities such as road and urban development. The analysis of these variables, the strengths and weaknesses of the project, as well as any data limitations will allow for the identification of areas that should be focused on for future research. The results of this study are also compared to historic records of shoreline change on Oahu and Kauai, compiled by the Coastal Geology Group of the University of Hawaii. This allows for further ananlysis and comparisson of areas that experience coastal erosion.
