Justine's GIS Blog

For this week's blog post we were asked to recreate our Assessment maps from Thursday's class. The maps required: 1. Counties color-coded by 1942 collegiate football conference and the boundary of each conference. Label each conference on your map. Do not include the original map. 2. The number of conferences within 100 miles (Statue Miles) of each county. Include the conference boundaries. 3. The 1940 population by county for only the counties within 50 miles of a collegiate conference. Include the conference boundaries. My first map I georeferenced the map provided and then used polygons to create the boarders of each conference. I think spatial joined the conferences (and names) to the counties layer. This allowed me to run a "select by location" which I intersected the boundaries and counties, which allowed me to color coordinate the conferences. The second map required me to find how many conferences were within 100 miles of all the counties. To do this I ran a s...

For this week's blog I decided to look at the hurricane paths in the United States between 1970-2010, by decade. What I was hoping to look at was the path of the hurricanes on land, the counties affected within a 25 mile buffer, the black population in relation to these hurricanes, any patterns over the forty years, and lastly look at tornado patterns during the same timeframe. I ended up with four map for three different inquiries. What I was hoping to track was first the historical risk over the span of forty years. Second, if the black population was continually more impacted by hurricane and tornadoes. Lastly, the historical risk of tornadoes across the US; and answer the question on if the risk has increased, decreased, or remained consistent. Map 1 shows the hurricane land fall paths and the 25 mile buffer of impacted counties. The impact zone buffers are broken into two colors. The counties boarded in black are all the counties that were impacted. The counties boarded in pur...
