Modes of Analysis: Area Analysis
the study of physical and human features of particular areas, regions, or places; involves surveying, describing, and compiling data; regional geography
• Areal differentiation
• Site
• Situation
• Location
• Geographical grid and coordinate system
• Latitude
• Parallels
• Longitude
• Meridians
Area Analysis: Areal Differentiation
describing and explaining differences between places
Areal Differentiation: Site
absolute location of a place, can be described in terms of latitude and longitude or in terms of place characteristics
Areal Differentiation: Situation
location of a place relative to other places, how far or near, easy or difficult; influences accessibility to resources, roads, markets, etc.
Area Analysis: Location
where things are on Earth
Area Analysis: Geographical Grid and Coordinate System
a system of lines drawn on maps to help locate places on the Earth
Geographical Grid and Coordinate System: Latitude
angular distance North and South of the equator, 0-90 degrees; most important
Geographical Grid and Coordinate System: Parallels
horizontal lines connecting all points of same latitude
Geographical Grid and Coordinate System: Longitude
angular distance East and West from prime meridian, 0-180 degrees
Geographical Grid and Coordinate System: Meridians
vertical lines connecting all points of same longitude
Spatial Analysis
location analysis, seeks patterns in the distribution of physical and human phenomenon, and in movements across Earth's surface
• Distribution

• Concentration
• Pattern
• Region
• Formal region
• Functional region
• Vernacular region
Spatial Analysis: Distribution
position, placement, or arrangement of a phenomenon through space
Distribution: Density
the frequency of the occurrence of a phenomenon in relation to its geographical area, quantity (grads per square mile, etc.)
Distribution: Concentration
the distribution of a phenomenon within a given area (clustered, dispersed)
Distribution: Pattern
the arrangement of phenomenon within an area (linear, circular, irregular)
Spatial Analysis: Region
more or less bounded division of the Earth that is defined by one or more distinctive physical or human characteristics or features that distinguishes it from other regions (diet, religion, vegetation, etc.)
Region: Formal Region
defined by one or more common physical or human traits (climate, languages)
Region: Functional Region
defined by interaction between nodal (central) and surrounding places, centralized services (transit districts, newspaper delivery, etc.)
Region: Vernacular Region
based on perception, defined by shared subjective images, stereotypes, language, mental maps (The South, Bible Belt, etc.)

Climate
the statistical summary of weather over time and space

• Rule of thumb: 3.5 degree drop per 1000ft rise in elevation
• Cooler in mountains/inland
• Warmer in lowlands/near oceans and lakes
• Variations in Precipitation
• Varies over place and time (seasonal change impacts timing and amount of precipitation at different places
• Lower latitudes: more fluctuation and feature higher annual worldwide precipitation (ITCZ)
• Variations impact supply in water table and consumption in biosphere, magnitude of evapotranspiration
• Precipitation
