Geog 222 Lecture Outline: Course Conclusions
Update: 12/9/14

The Power of Maps...



Maps, Visualization, GIS

1. Knowing our Surroundings

2. Visualizing the Human and Physical Environment



Mental Maps

Building our mental maps, characteristics, applications; psychogeography & sensory mapping



Cartographic Maps

1. Basic Components of Cartographic Maps

2. The Cartographic Process: Map Making and Map Use

3. Map Making: Mapping Constraints: factors which influence how and why a map is created

4. Map Use



Exercise 2: Finding 'Real' Maps: with a focus on maps of 'home.'



A Cultural History of Cartography

One facet: development of locational accuracy

Another facet: linked to cultural characteristics: religion, belief, exploration, trade, colonization; scientific interest and economic factors



Geographic Data and Data Sources

1. How do we acquire data?

2. How are the data organized?

4. How are the data inventoried?

5. How is data derived?

Exercise 3: Geographic Information on the WWW



Computers and Mapping

Exercise 4: Mapping & GIS Tools



Map Projections

Exercise 5: Map Projections (on final)



Map Locational Reference Systems (Coordinate Systems)

Five different map coordinate systems

Coordinate systems primarily used to locate POINTS

Coordinate systems primarily used to locate AREAS



Map Abstraction

Map (or cartographic) Abstraction: "the process of transforming geographic data, which represents the actual human and physical environment, into a map

1. Map Content: given the infinite detail in the physical and human environment, what is selected to be mapped and at what scale?

2. Map Scale: "the extent of size reduction from the environment to the map; the ratio of map distance to ground distance"

3. Map Generalization: the systematic process of removing detail from (and sometimes adding detail to) the objects and phenomena to be mapped

4. Map Symbolization: the systematic process of creating graphic marks which represent the objects and phenomena to be mapped



Exercise 7: Mapping Your Own Data


...and finally, the final!




What the future holds...


Geographic Information Systems: Big GIS - higher costs, higher skills...


Virtual Globes: GIS for the people...


Map Hacking / Mashups: More GIS for the people...


Getting more and more data: location aware devices everywhere: Global Positioning Systems
