Starter How do maps positively impact our lives? How do maps negatively impact our lives?

Review of Scale Small-Scale Large-Scale What does scale tell us?

Identifying Places 1. Place Name toponym - Names derived from people, religious affiliation, physical features, or origins of its settlers 2. Site - the physical character of a place Characteristics include climate, water sources, topography, soil, vegetation, and elevation. 3. Situation - the location of a place relative to other places Relative location

Utah is made up of mountains, valleys, and sagebrush Site or Situation? Utah is made up of mountains, valleys, and sagebrush

Provo is south of Salt Lake City Site or Situation? Provo is south of Salt Lake City

3 Properties of Distribution 1. Density: mass/volume; the amount of something in a set area High density area is going to refer to metropolitan cities as they will have high amounts of people in a small amount of physical space 2. Concentration Clustered, dispersed 3. Pattern Linear, circular, random, etc.

Density High Density Low Density

Density = Mass/Volume = ♥ Back to the Future - You Are My Density

Concentration (not density!) Clustered Dispersed

Pattern

Top: Lower density Top and middle: Both dispersed Middle and lower: same density Lower: More clustered

Christaller’s Central Place Theory Cities exist because they have services and then suburbs develop around them

Sense of Place When a location has a strong identity and character that is deeply felt by local inhabitants and by many visitors Does Utah have a strong sense of place? Salt Lake City? Price? Paris, France?

Distance Distance is the measurement of how far or how near things are to one another Proximity indicates the degree of nearness Meters, miles, kilometers, etc. Straight line distance (as the crow flies) or travel distance

Distance Distance decay - The interaction between two things declines as the distance between them increases Ethnic groups Radio signal Etc. The friction of distance indicates that when things are farther apart, they tend to be less well connected

Space-Time Compression The shrinking “time distance” between locations because of improved methods of transportation and communication

Article- Ptolemy to GPS

Article Questions What is the main point that the article is trying to make? (What does the author say our goal is with maps?) Do you agree with the author? Is there anything that you would add to this article?

Contemporary Geographical Tools Help us learn more about characteristics of places Remote Sensing – the scanning of earth by satellite or aircraft to obtain information about it GIS – geographic information system Designed to capture, store, and analyze spatial or geographic data GPS – Global Positioning System

Layers of a GIS Fig. 1-5: A geographic information system (GIS) stores information about a location in several layers. Each layer represents a different category of information.
