My approach using GIS

• I have used GIS to draw the tracks of Various
  Hurricanes.
• Acquiring Data
• National Hurricane Center
• Data Used
• 1995-2002

7
Steps Involved

• Downloading the data into a Microsoft Excel Sheet
• Sorting the data to fit the GIS formats
• Getting the World Map

8

• Importing the Excel sheets into GIS
• Creating a Shape file
• Creating a New Geo database
• Clipping the Part of World where Hurricanes
  Strike
• Extracting the US Cities struck between
  1995-2002
• Generating a Time Series
• Showing the Time series Variation Using Tracking
