Throughout this first project, we looked at Network Analysis and how it can be used to prepare the citizens of Tampa Bay from a Hurricane that's about to make landfall. Since this first assignment was the prepare week, the main objective was to acquire the data necessary for a base map and further analysis. The data was all provided by UWF, which includes: a Digital Elevation Model (DEM), streets, point data files for fire departments, police departments, hospitals, a National Guard Armory drop location, and schools designated as shelters. All of this data was used in compiling the base map shown below. The biggest aspect to this weeks project was preparing the potential flood zones. This was done by reclassifying the original DEM into appropriately usable elevation increments. The reclassified DEM was then converted into a polygon feature class for easier processing. It was discovered that all areas that have less than 6 feet of elevation will most likely have flooding. To show this even further, a "Flood Zone" feature class was created to display the areas that are at risk for flooding. The Flood Zone layer is shown with low opacity to better display the variations of elevation.
The map below shows the Tampa Bay area as it relates to most likely flood zones, with transportation arteries that would be affected.
