GIS 4048: Applications in GIS Module 4

Module 4:  Hurricanes

This week’s lab involved the creation of two maps related to Storm Sandy that hit the New Jersey shore in October 2012.  The lab covered the use of Excel data, creation of custom symbology, advanced labeling, map grids, the effects toolbar, setting geodatabase attribute domains, and editing features using domain properties.

The first map depicts the status and path of Storm Sandy as it hit the New Jersey shoreline.  The path was created by using the Points to Line Tool in ArcToolBox thus creating a polyline feature class from a points feature class containing data for Storm Sandy.  The hurricane specific symbology was created with Character Marker Symbols and saved to my user profile for future use.  The meridians and parallels were added to the map by setting a new grid under the data frame properties.  Maximizing map space became a little challenging as the longitude and latitude markers take print area space.  I was able to re-align the latitude readings vertically to save space.

The second map depicts structural damage to one side of street in the Tom’s River Township based on pre and post storm imagery.  The Slider Tool of the Effects Toolbar was used to swipe (peel on/off) the imagery to determine structural damage based on the before and after imagery.  A new point feature class was created along with Attribute Domains to limit possible values for the various damage assessment fields thus reducing data entry errors. 

Below are the two maps depicting Storm Sandy’s path and damage assessment.
