Comparisons of Data Classification Techniques


Personally, I think that George Jenks' map style/data classification technique of Natural Breaks is the one best used here. We used Escambia County, FL's census data to demonstrate the population of black people in the area. I feel that the Natural Breaks most accurately depicts trends and such.

Famous Contributors to Geography and Cartography

John Paul Goode (1862-1932) was one of the key American geographers early on. He spoke out against the “Evil Mercator” in 1908 at the meeting of the American Association of Geographers. He developed the Goode’s Homolosine projection that aggravated the world by not having America at the center of the world (Goode’s map). Along with a few students, Goode developed Goode's World Atlas, published by Rand McNally even today in it's 22nd edition.

Erwin Raisz (1893-1968) was one of the first cartography students in the United States, and was in charge of Harvard's map collection for twenty years and taught during that time. He is well-known for his intricately detailed pen-and-ink, hand-drawn maps. To this day, his family continues to publish his work through Raisz Landform Maps. He is also known for the first cartography textbook in English (General Cartography) in 1938.

George F. Jenks was a researcher from the University of Kansas who looked into the statistical importance of maps, and he discovered that contemporary maps at that time were significantly lacking. He wanted to teach simple map-drafting and getting back to the basics to ensure that future cartographers produced quality work after the so-called "golden age" in World War II that brought cartography out as a real discipline. He also pushed for new inks and techniques that would better show our world.

Waldo Tobler (born 1930) is an influential geographer and cartographer that developed the first law of geography: "Everything is related to everything else, but near things are more related than distant things." It is related to to Newton's Law of Universal Gravitation. It lead to the creation and still influences geostatistics. He currently teaches at UC-Santa Barbara, and more information can be found about him here.
