LANDSAT data was used to create the base layer of this map, and was downloaded from the Hawai`I State Office of Planning. The tsunami zone shapefile was downloaded from the same source. Historical shark attack point data was obtain from Esri’s online shark attack map. I opened the interactive large-scale map in ArcMap and created a layer of shark attacks in the island of Maui only, then overlayed with the basemap and tsunami zone. The purpose of using LANDSAT imagery to create this map was to show the island in a more three-dimensional way, which helps to explain the narrow extent of the tsunami zones and also give a better sense of the topography of the island. Also, the LANDSAT images are more visually appealing and interesting that a simple polygon.

Original map is 8.5 x 11 inches. Click here for full-sized pdf.
