In this module, we delved deeper into the impact of Hurricane Sandy, focusing on damage assessment. To complete this task we learned how to create raster mosaics for pre and post hurricane, created attribute domains to categorize damage, and utilized our skills to decide how to summarize the data from the damage assessment.
To begin we used meteorological data to create a storm track map showing Sandy's progression from below the Caribbean islands on October 22nd, 2012 until it made landfall on the northeast coast of the United States as a Category 1 hurricane on October 29th, 2012.
To complete our damage assessment we used our pre and post imagery to assess the damage to structures in our study area. Each property in our study area had to be identified and categorized according to the domains that we created. Each domain provided a choice for what level of damage each property appeared to have based on our remote imagery. After assessing the damage and symbolizing the data we were tasked with creating a polyline feature class representing the pre-storm coastline. I then created a multi-ring buffer establishing a 100m, 200m, and 300m buffer. This was used to summarize the data and help discern and identify patterns. Below are my results:
