My Customized Google Map for Tornadoes

The data my map is displaying is the starting points for tornadoes that touched down in Oakland County in the state of Michigan. The data is between the years of 1953 to 2015. I found the data on the sit, data.gov. This data is credible because it was provided by the National Oceanic and Atmospheric Administration, the OCIT, and Matt Malone of Farmington Hills GIS. The location marks on the map represent each tornado that has gone through the county. The colors represent how strong the tornado was on the Enhanced Fujita scale. The red color represents a tornado that is an EF0 level. The yellow color represents an EF1 and the green color signifies an EF2 tornado. The light blue color was an EF3 and the purple color represents an EF4 tornado. The Enhanced Fujita scale does go all the way to an EF5 tornado. However, Oakland County has never had an EF5 tornado since the records started being kept in 1953. I think this map is important to show to my audience because it is interesting to see how many tornadoes have been through a particular area over a long period of time. Even in a place as far as Michigan, where we don't think tornadoes should really happen, there have been numerous in the area over the last 70 years. Also, having them color coded by how strong the tornado was shows my audience the impact these communities faced from these storms. I used Google Maps to display my data because I believe it was the easiest way to show the data and would give a pinpoint location on where the tornadoes happened.
