City Growth and the Viz Wall

For the first official week of Urban Environments, we went to the Viz Wall in the new Petit Science Building on campus. Dr.Hankins lead a presentation about city growth in the context of Atlanta. There has been an ongoing project going on for a while in which 1600 (?) old maps from Atlanta are being digitized and geo-coded to be overlaid onto current GoogleEarth maps, allowing users to view change over time. I find this stuff fascinating, and I am very excited for it to go public in the very near future! Here are some photos from the day:

Interesting things I learned about Atlanta's formation:
- Atlanta is one of very few cities in the world to be located nowhere near a body of water or major waterway. It instead grew from the intersection of two major railways.

- The early city was bisected by these rail lines, so they built numerous viaducts over the railroad tracks which are still in use today.


- Until the 1930's, Atlanta's major form of transportation was the streetcar, which has completely disappeared today. (Plans for new streetcars are in development.)

- A new "bisection" of neighborhoods arose with the implementation of the federal highway system starting in 1956.

- Trends of urban renewal and slum clearance have greatly shaped Atlanta, and have destroyed many former neighborhoods with racial bias. For example, the section of town which now houses the Atlanta Civic Center was once a predominantly African-American neighborhood called Buttermilk Bottoms.

- Freedom Parkway was originally intended to be a major highway called I-485, extending to Stone Mountain, but it was rejected.

- Atlanta ranks far behind many other cities in terms of greenspace, but the Beltline project is working to expand that dramatically.

- Fulton County Stadium was a purely speculative project bought with federal slum dollars, built on land not owned by the city, for a baseball team which had not yet been secured by purchase from Milwaukee.

Information about Contemporary Urbanization & Environmental Dynamics
from our text, Cities & Nature: (pg.65-95)
1) The three new trends in urban dynamics are:
    a: throughout the twentieth century, the world has become increasingly urban
    b: cities have continued to grow larger
    c: the creation of giant urban regions and megacities
2) In the megalopolis of the American northeast, the quantities of human use of materials have dramatically risen. The number of cars has almost quadrupled, releasing tons of exhaust. Water withdrawals have increased by over 150% in fifty years. The city of New York generates approximately 100,000 tons of garbage daily. The consequences of this are found in "increasing population growth in association with increased affluence and spiraling consumption producing a greater environmental footprint and increased strain on the natural systems that sustain and nurture life" (Short 73).
3) The five new forms characterizing cities now are:
    a: waterfront redevelopment
    b: superfund sites / brownfields
    c: sprawl
    d: the new industrial city
    e: shantytowns
Atlanta exhibits signs of sprawl and superfund sites / brownfields, and perhaps even shantytowns.

a blog is born

Hello, everyone! My name is Ben Nicoara, and welcome to my new blog!
I am a senior at Georgia State University, and I am finishing up my undergraduate studies in Geographic Informations Science. (a.k.a. GIS)
Honestly, this blog is a part of my requirements in a very intriguing class I just started taking entitled 'Urban Environments,' but I think I could actually see this blog surviving and growing long past the end of this semester, and even graduation!

I've always been somewhat of a map geek, ever since childhood, but since being at school in a huge, dynamic world city like Atlanta, my interests have definitely expanded. Histories and concept ideas for former and future urban planning/redevelopment projects are an area of focus for my extra-curricular interests. Also, mass transit network expansion (generally referring to heavy-rail and light-rail) definitely catches my attention too. I enjoy researching news about other cities across the globe, and how they are dealing locally with their issues concerning: population boom, transportation infrastructure, livability and greenspace, resource/food scarcity, public health and epidemics, etc.

my favorite city on earth: Paris, France
exploring Zurich, Switzerland
I really hope that somebody out there will find my thoughts interesting. Feel free to read, comment, and share anything and everything you find interesting on the topic. I am definitely open to learning more and more! Blog posts will appear at least once weekly, but hopefully more than that If I find the time for it.


- sincerely, Ben
