Thinking Geographically • 4 types of maps • 5 themes of geography • 3 types of regions • Site vs. Situation
Mercator Projection - 1569 • Low distortion on land shape • Distortion is greatest at the poles
Robinson Projection - 1963 • Distorts shape, size, distance, and direction evenly, but preserves all four the best at the Equator
Goode Projection - 1923 • Land masses are true • Distances are distorted
Lambert Projection - 1772 • Direction is true from center point • Distorted shapes and direction at the edges • Views one hemisphere of the world
5 Themes: Place • A specific point on Earth
5 Themes: Region • An area on Earth distinguished by a combination of culture and physical features
5 Themes: Scale • Relationship between the portion of Earth being studied and the Earth as a whole
5 Themes: Space • Refers to the physical gap between objects
5 Themes: Connections • Relationships among people and objects across space
Types of Regions: Formal (Uniform) • An area within everyone shares one or more distinctive characteristics
Types of Regions: Functional (Nodal) • An area organized around a node or focal point, diminishes in importance as it grows outward
Types of Regions: Vernacular (Perceptual) • A place that people believe exists as part of their cultural identity
Site vs. Situation Site Situation The location of a place in relation to others Example: Lebanon is approximately 60 miles south of Louisville • The physical characteristic of a place • Example: Marion County’s site characteristics include knobs, rivers, and a high percentage of agricultural land
Latitude and Longitude • Latitude – runs flat and are parallel • 0⁰ Latitude is the Equator • Latitude lines go from 90⁰ South Latitude to 90⁰ North Latitude • Longitude – runs up and down, meet at the poles • 0⁰ Longitude is the Prime Meridian, 180⁰ Longitude is the International Date Line • Longitude meridians go from 0⁰ to 180⁰ and are measured east to west in relation Greenwich, England
Map Distortions • Shape • Size • Direction • Distance
Types of Diffusions • Relocation – physical movement of people • Expansion – snowball effect • Hierarchical – spreads from nodes of authority • Contagious – rapid and widespread diffusion • Stimulus – as an idea spreads, part of its concept is lost, the rest continues to be spread
