Final Project Map-Habitat Types in the Ocmulgee Oil Fields


This map was developed using existing data found in "The Impacts of Highway Construction in the Ocmulgee Old Fields Reserve and The History of the Ocmulgee Old Fields Reserve in Carbon-Dated Peat Soils" by Dr. Brian Rood and Dr. Laura Lackey. The original study, compiled in 2001, contained a similar map showing various habitat types along three transects running from I-16 into the Old Fields. In order to modernize the existing map, a satellite image was combined with a topographic map via georeferencing, which proved to be much more difficult than originally anticipated. Individual layers were then added to represent the 11 different habitat types, with the end result displayed above.*


*Ideally, information contained in a metadatabase could have been added showing types of soil and plant life along the same transects, however this process would have been long and arduous and would not have been complete by the due date. Additionally, because the topographic map contained purple coloring over the buildings, some structures in the map still appear to be purple, potentially distracting from the various multi-colored habitat types.

Geocaching

Geocaching is a high-tech treasure hunting game played throughout the world by adventure seekers equipped with GPS devices. The basic idea is to locate hidden containers, called geocaches, outdoors and then share your experiences online. Geocaching is enjoyed by people from all age groups, with a strong sense of community and support for the environment. Hunters can search for 3 different types of geocaches:
-Geocoins: Collectible Geocoins come in all shapes and sizes, and can be tracked in the same way as Travel Bugs. Here you can log a geocoin you found, activate a new geocoin, locate geocoins near you, and find out how to create your own.
-Travel Bugs: A Travel Bug is a trackable item that moves from place to place, picking up stories along the way. Here you can add your own story, or live vicariously through each bug's adventures.
-Promotions: From time to time Groundspeak will host various promotions involving trackable items. Here you will find information on all of the past and present promotions involving Geocaching.com Trackables.
-How to Start Geocaching:
1)Register for a free Basic Membership.
2)Click "Hide & Seek a Cache."
3)Enter your postal code and click "search."
4)Choose any geocache from the list and click on its name.
5)Enter the coordinates of the geocache into your GPS Device.
6)Use your GPS device to assist you in finding the hidden geocache.
7)Sign the logbook and return the geocache to its original location.
8)Share your geocaching stories and photos online.

Maps with hidden agendas:

Notable Cartographers:

John Paul Goode- From encyclopedia.com: "John Paul Goode...taught geography at the Univ. of Pennsylvania (1901-17) and at the Univ. of Chicago (1917-28). Goode is noted for devising the interrupted homolosine projection, which combines the best qualities of the homolographic (or Mollweide) and sinusoidal projections; it is widely used for maps that portray global distribution. Goode edited many maps and books on geography, including the well-known Goode's School Atlas (1923; many later editions), now entitled Goode's World Atlas."

Erwin Raisz- From http://www.raiszmaps.com/: "Raisz Landform Maps were created by Erwin J. Raisz (1893-1968) an internationally renowned cartographer. They are minutely detailed, hand drawn, pen and ink maps, based on field observations and aerial photography presenting a real portrait of the face of the earth."

George Jenks- George Jenks is best known for developing the Cartography program at the University of Kansas.

Waldo Tobler- Tobler created what is known as "the first law of geography which states that "everything is related to everything else, but near things are more related to each other."

Pioneer Universities in Cartography:

University of Wisconsin
University of Kansas
University of Washington
University of South Carolina

Interesting Facts:

It is commonly believed that the world's oldest map is from Ancient Babylon and dates back to the 6th century b.c. However, archaeologists have recently discovered what they believe is man's earliest map, dating from almost 14,000 years ago according to the British newspaper The Telegraph: http://www.telegraph.co.uk/news/worldnews/europe/spain/5978900/Worlds-oldest-map-Spanish-cave-has-landscape-from-14000-years-ago.html

Quiz 1

Question 1- In order to be a good cartographer, one must first understand that maps are constructed by overlapping layers of information on top of one another. Therefore, the cartographer must possess excellent analytical skills to be able to anazlyze data, create the necessary layers, and organize them into a map that anyone should be able to view and understand. Also, the cartographer must have a sense of what works visually in order not to create a confusing mix of colors, shapes, and words. Finally, the cartographer must be able to understand the needs of his client and be able to translate those needs into an easy-to-use visual representation.

Question 2- A good map must first be easy to look at. While this sounds simple, it is imperative that the user be able to identify what information he is looking for on the map. Also, a good map contains features pertinent to the map topic (i.e. elevation markers on a topographic map) and corresponding attributes related to those features presented in a user-friendly way, as well as iconic imagery to make things readily identifiable. A bad map is one that is not user-friendly, perhaps by using color schemes that are hard to look at, making it hard to read words and data contained in the map. Also, bad maps may have incorrect layering and jumbled or confusing features or no labeling of important data.
