1. I. Spatial Interaction & Distribution

2. A. Location, Direction, & Distance
1. absolute & relative location:
absolute location: a physical place measured by latitude and longitude (the address of a house is also an absolute location)
relative location: location in relation to other places
Real-time GPS Tracking systems

3. site & situation:
1.site: the physical and human characteristics of an absolute location.
2. situation: the relationship of a place to other places.
Singapore
lower Manhattan Island

5. 3. absolute and relative directions:
absolute direction: north, south, east, west
relative direction: “the middle east,” “west coast,” “deep south”
4. absolute and relative distance:
absolute distance: cm, km, miles
relative distance: measured by time

6. B. Size & Scale What is map scale?
--a consistent relationship between size on the map & size in real life
1:24,000 scale (one inch = about 0.4 miles)
1:100,000 scale (one inch = about 1.5 miles)
Does a large-scale or small-scale map show a larger area of land?
small-scale= big area, little detail. Maps of the world which fit on two 8 1/2 by 11 inch pages are very small scale, about 1 to 100 million.
large-scale=small area, lot of detail. Large scale maps will have a RF of 1:50,000 or greater (i.e. 1:10,000).

8. National Level... Deaths from Cancer
Lowest Level

9. State Level... Deaths from Cancer
Highest Level

10. Local Level... Deaths from Cancer

12. C. Interrelationships Between Places
The ideas of relative location & relative distance leads to
a fundamental spatial reality:
A. Places interact with other places in structured &
understandable ways through the following:
Accessibility: ability to interact with a particular location
Connectivity: interactions between several locations
Spatial Distribution:
density (measure of the number of something in a defined area)
dispersion (amount of something is spread out in space; types: linear, clustered, or scattered dispersion)
pattern (the geometric arrangement of objects in space)

13. Pattern of a distribution to uncover sources of disease?

15. Spatial behavior of people: population

19. B. Regions region: earth areas that display some sort of uniformity
3 types of regions:
formal regions: an area which has one or more common distinctive characteristics, such as language or economic activity
i.e.: Florida state boundary; US-Mexico border

21. functional regions: an area defined by its function (interactions & connections)
i.e.: a downtown area

22. Formal & Functional Regions
The state of Iowa…formal region
Areas of influence of various television stations?

23. perceptual (or vernacular) regions: emerges from people's “sense of a place” (all about feelings & images of a place)
i.e.: The South, “the hood,” Chinatown

24. FORMAL, FUNCTIONAL, OR PERCEPTUAL?
