The Five Themes 1. Location 2. Place 3. Human-environment Interaction 4. Movement 5. Region
Location • Where is geography. • A statement, not a question • Society expects geographers to know about locations, places, and regions. • When is history. Lots of what disciplines. • Geographers use a special kind of graphic [maps or charts] to help illustrate and communicate information about locations • Cartography = the science and art of map making • Map reading [and folding] are skills that can be learned
Location • Maps are a generalization of reality [simplification] • Scale = a numerical way to relate the map to the world • Representative fraction: distance on the map distance in the world • 1:5,000,000 1 inch on the map = 5 million inches in the world or 1 inch = 78.9 miles
Location • Absolute and relative location • Absolute • An exact or fixed location on the Earth • Typically use a grid system to describe absolute location • Latitude and longitude • Many other coordinate systems exist • Township and Range • State Plane • UTM • Street addresses
Location • Absolute and relative location • Relative • Location connected with other landscape features • Many ways to ‘make the connection’ • Distance and direction [5 miles east of ______] • At a reference point [at the Falls of the Potomac] • Time [25 minutes west of Hays on I-70] • Kansas is north of Oklahoma • Across the street from Pizza Hut
GPS = Global Positioning System • A fully functional Global Navigation Satellite System • GPS uses a constellation of between 24 and 32 satellites that transmit precise microwave signals, that enable GPS receivers to determine • their current location • the time • their velocity (including direction) • After Korean Air Lines Flight 007 was shot down in 1983 after straying into the USSR's prohibited airspace, President Reagan issued a directive making GPS freely available for civilian use as a common good.
Basic Triangulation X X Where are all the locations that are a known distance from a point? X
Location • Two hands clapping [you need both] • Site and situation • Condition and connections • Relationships within places [Place] and relationships between places [Movement]
