1. OBJECTIVE
TWW compare and contrast map scale and geographic scale in order to evaluate why a geographer would analyze any phenomena at various scales

2. Free Response Question (6 pts.)
Technological Innovations have greatly influenced the methods in which geography can be done today.
Describe three technological advances that have dramatically changed the capabilities of the discipline of geography
Provide an application for each type of technology

3. GIS – 2 points
DESCRIPTION - Take the phenomena of various thematic maps and combine/layer that information into one “map” so to analyze the relationship amongst the data
APPLICATION - Governments hire geographers to zone and plan the use of land. GIS would allow the geographers to easily see the relationship of various phenomena to make the best possible choice for the use of the land.

4. GPS – 2 points
DESCRIPTION – a satellite based system, maintained by the US Air Force which gives precise location and time of any position on the globe.
APPLICATION - For years, geographers have utilized longitude and latitude as a means of giving exact location. The GPS removes any of the geographical error that might have been involved in the traditional method of cartography.

5. Computed Generated Maps – 2 points
DESCRIPTION – traditionally, maps were hand drawn utilizing scaling methods, which were subject to human error. This allows the geographer to input the information and the computer generates the map.
APPLICATION - a computer generated map minimizes the human error involved in traditionally map making. As geographers help to solve border disputes between countries, a computer generated map would give the precision to prevent further disagreements.

6. Analysis #1 Compare the two maps below.
What conclusions could you draw about the information presented?
How could advances in technology increase the geographer’s understanding of the information?

8. SCALE  Two Levels of Importance
Map Scale  Distance on a map
Geographic Scale  Interpretation of Geographic Phenomena

9. Map Scale: Distance on a Map
Measured/Displayed in Three Different Ways
Fraction: 1/24,000 ft.
Ratio: 1:24,000 ft.
Sentence: 1 inch equals 24,000 ft.

10. Geographic Scale
Spatial Perspective: observing variations in geographic phenomena across space
Phenomena may be environmental, cultural, or economic

11. Scale: Geographic Interpretation
Varying levels of scale changes the spatial perspective of the geography

12. Would this map be helpful to Barack Obama’s Campaign Manager?

13. How could you “re-scale” this map in order to make it more useful for Obama?

14. How would this “re-scaling” be extremely helpful to Obama?
