Module 4: Coastal Flooding

 This lab followed had many moving parts which required the manipulation of raster via reclassifying and converting to vector data.

Analysis One

This analysis used used LiDAR data from before and after a storm. After converting the data a final raster was create showing the difference or extent of impact. Shown below 
its easy to identify the areas which experienced the greats impact, denoted in red.
 
Storm Impact

 

Analysis Two

Here the lab provided data to quantify the overall impact to a geographic area. This required converting the a raster into a vector after reclassifying to a specific value.

Analysis Three

This built on the previous to analysis which compared the impact on building in Collier County, Florida based upon two different digital elevation models (DEM). One being a derived from high resolution LiDAR and the other a standard USGS DEM. 

Give the extend of the study area and required detail showing to a neighborhood level creating a single map on a 8.5 x 11 document is nearly impossible. Which is when a map series comes in handy. I have create hundreds of map books using this feature with ArcGIS Desktop (a.k.a ArcMap) but never with ArcGIS Pro. Nothing with the process has change just things in different locations. The series only contains the location in the grid which intersects an area from the LiDAR floodzone and buildings. This excluded areas which do not show any impacted building within the study zone. Nonetheless, the series contains 69 maps, totaling 70 pages with a title/index page that include the tabular data expected by the lab.

Enjoy!
