Applications in GIS - Module 4 - Coastal Flooding

This week's module for Applications in GIS we were tasked with conducting three different coastal flood analyses. With the use of digital elevation models we delineated coastal flood zones. These analyses utilized both raster and vector data to ultimately achieve our desired result. This lab proved to very challenging for me as I had some issues early on that prohibited me from completing all the steps.

The initial analysis consisted of creating a raster of coastal New Jersey post hurricane Sandy showing erosion and buildup. Below is my map for this analysis where the darkest red shading represents the greatest erosion and the darkest blue represents the areas of the most buildup.

For the final portion of the lab we were tasked with analyzing storm surge in Collier County, Florida. Two DEMs were initially used one by the USGS and another LiDAR derived used to create 1 meter storm surge models. These were to be used to analyze and determine the number of buildings that would be affected by a 1 meter storm surge. Unfortunately, I was unable to complete this objective in its entirety. I was unable to understand the Region Group tool so I skipped it so my data isn't as accurate as it should be. Below is a map showing my two storm surge models.

Overall, this was a challenging model for me because I had some issues understanding some instruction starting in analysis 2. After getting behind I struggled to regroup after becoming frustrated. That said, I was able to get back on track and make some progress with analysis 3 even though I was unable to complete it in its entirety.
