The above sequence of images and maps took about 1-hour to construct using the USGS Hawaii Data Clearinghouse data, Global Mapper and Marplot. Normally the shoreline would have required many hours to digitize. And forget about the hypsographic layer. I don't have the expertise, resources, time or inclination. However, like any map-aholic, I love the addition of hypsographic data. Especially using mapping software that lets you easily switch between layers of information.
What I could have done to enhance the map would be to separate the hypsography layer into specific elevation levels (100-m, 200-m, etc.). I can't get over how easy it was to construct the above maps. When the data is available and you have the software that is easy to use, maps follow quickly. Happy mapping!
