Chapter One Thinking Geographically 5 THEMES OF GEOGRAPHY Place Sense of place: infusing a place with meaning and emotion. Perception of place: belief or understanding of what a place is like, often based on books, movies, stories, or pictures. Movement Spatial interaction: the interconnectedness between places depends upon: Distance Accessibility Connectivity Cultural Landscape The visible human imprint on the landscape. Religion and cremation practices diffuse with Hindu migrants from India to Kenya. Two Types of Maps: Reference Maps - Show locations of places and geographic features - Absolute locations Thematic Maps - Tell a story about the degree of an attribute, the pattern of its distribution, or its movement. - Relative locations What are reference maps used for? What are thematic maps used for? Reference Map Thematic Map What story about median income in the Washington, DC area is this map telling? Mental Maps: maps we carry in our minds of places we have been and places we have heard of. can see: landmarks, paths, etc. Activity Spaces: the places we travel to routinely in our rounds of daily activity. How are activity spaces and mental maps related? How Geographers Address Location • Maps – – – – Who was the first person to use the word “geography?” Early mapmaking Map scale Projection U.S. Land Ordinance of 1785 • Contemporary Tools – GIS – Remote sensing – GPS Township & Range System in the US CONTOUR = TOPOGRAPHIC MAP - Large scale map - Quantitative representation of relief - Natural + man-made features -Originally used by the military to plan for battle & defensive emplacements -Used in architecture, mining, recreation, urban planning, etc. - Notice colors used - Contour lines are curves that connect to contiguous points of the same altitude - V: stream valleys - O: can show uphill or downhill - Spacing of contours: Indicate shallow or steep slope. Fig. 1-4: Principal meridians & east-west baselines of the township system. Townships in northwest Mississippi & topographic map of the area. Principal Meridians & Baselines U.S. Land Ordinance of 1785 Tallahatchie River, Mississippi in Township Sections The Tallahatchie River is located in the southeast and southwest quarter-sections of Section 32, T23N R1E. GPS versus GIS Global Positioning System versus Geographic Information Systems What can GIS do for you? REMOTE SENSING Remote Sensing is any technique used for measuring, observing, or monitoring a process or object without physically touching the object under observation. - Use satellites orbiting the Earth or from other longdistances. - Optical and radio telescopes, cameras, even eyesight are types of remote sensing. Remote Sensing: a method of collecting data by instruments that are physically distant from the area of study. LARGE SCALE MAP Scale Differences Maps of Washington State Which is the small scale map? Which is the large scale map? * Distortion is greatest in small scale maps! Fig. 1-3: The effects of scale in maps of Washington State. (Scales from 1:10 million to 1:10,000) Washington State (1:10 million scale) Western Washington (1:1 million scale) Seattle Region (1:100,000 scale) Downtown Seattle, Washington LARGE SCALE MAP (1:10,000 scale) Scale Scale is the territorial extent of something. The observations we make and the context we see vary across scales, such as: - local - regional - national - global Scale is a powerful concept because: - Processes operating at different scales influence one another. - What is occurring across scales provides context for us to understand a phenomenon. - People can use scale politically to change who is involved or how an issue is perceived. Tallahatchie River, Mississippi CONTOUR MAP A contour map has a large-scale detail and quantitative representation of relief. The topographic map of the U.S. Geological Survey has a scale of 1:24,000 Uniqueness of Places & Regions • Place: Unique location of a feature – – – – TOPONYMS Place names Site Situation Mathematical location • Regions: Areas of unique characteristics – – – – – Cultural landscape Types of regions Spatial association Regional integration of culture Cultural ecology PLACE What is the difference between SITE and SITUATION? SITE: SITUATION: * Describes where a • Describes the place is in relation to its characteristics where a surroundings (other settlement is located towns, uplands, & • Characteristics can rivers) include: * Purpose- we can - climate identify something from - water sources the land to direct people - topography to their desired location - soil - vegetation Think about why places were - latitude located where they are? - elevation Site: Lower Manhattan Island Fig. 1-6: Site of lower Manhattan Island, New York City. There have been many changes to the area over the last 200 years. Situation: Singapore Fig. 1-7: Singapore is situated at a key location for international trade. Situation Downtown Singapore Downtown Singapore is situated near where the Singapore River flows into the Singapore Strait. Perception of Place Where Pennsylvanian students prefer to live Where Californian students prefer to live World Geographic Grid •What are minutes? •What are seconds? Fig. 1-8: The world geographic grid consists of meridians of longitude and parallels of latitude. The prime meridian ( 0º) passes through Greenwich, England. •How are time zones calculated? World Time Zones •Names of the US time zones •Explain how time zones change (E,W) •International Date Line + significance Fig. 1-9: The world’s 24 standard time zones each represent about 15° of longitude. They are often depicted using the Mercator projection. REGIONS: - Vernacular or Perceptual Region - Formal Region - Functional or Nodal Region VERNACULAR REGION or Perceptual Region: FUNCTIONAL REGION (or Nodal Region): - •Region that has a defined node or center EX. Metropolitan area of Chicago - Defied loosely defined by people's perception Ideas in our minds, based on accumulated knowledge of places and regions, that define an area of “sameness” or “connectedness.” EX. The South The Midwest The Middle East FORMAL REGION: - An area where everyone shares in one or more distinctive characteristics - Can be defined by governmental or administrative boundaries EX. United States, German speaking regions in Europe - Physical regions fall under this category EX. The Rockies, the Great Lakes States Formal and Functional Regions Fig. 1-11: The state of Iowa is an example of a formal region; the areas of influence of various television stations are examples of functional regions. Vernacular Regions Fig. 1-12: A number of features are often used to define the South as a vernacular region, each of which identifies somewhat different boundaries. 9 or more regions within the United States! The meanings of regions are often contested. In Montgomery, Alabama, streets named after Confederate President Jefferson Davis and Civil Rights leader Rosa Parks intersect.

Environmental Modification in the Netherlands Polders – piece of land created by draining water from an area Fig. 1-15: Polders and dikes have been used for extensive environmental modification in the Netherlands. Environmental Modification in Florida Fig. 1-16: Straightening the Kissimmee River has had many unintended side effects. C-38 Canal Florida The canal has carried water with agricultural runoff and pollution into Lake Okeechobee ** Similarity of Different Places • Scale: From local to global – Globalization of economy – Globalization of culture • Space: Distribution of features – Distribution • Connections between places – Spatial association – Diffusion Globalization A set of processes that are: - increasing interactions - deepening relationships - heightening interdependence A set of outcomes that are: - unevenly distributed - varying across scales - differently manifested without regard to country borders. throughout the world. GLOBALIZATION POLITICAL CARTOON Globalization of the Economy Fig. 1-17: The Denso corporation (automobile parts manufacturer) is headquartered in Japan, but it has regional headquarters and other facilities in North America and Western Europe. GLOBALIZATION Transnational (multinational) Companies • They invest in foreign operations, central corporate facility, conduct research + development, operate factories & market products - not just where their headquarters + primary shareholders exist Globalization of Culture SPACE: Distribution: Density, Concentration, & Pattern •DISTRIBUTION: •DENSITY - arithmetic density – how? •CONCENTRATION - clustered - dispersed •PATTERN Fig. 1-18: The density, concentration, and pattern (of houses in this example) may vary in an area or landscape. Spatial distribution What processes create and sustain the pattern of a distribution? Map of Cholera Victims in London’s Soho District in 1854. The patterns of victim’s homes and water pump locations helped uncover the source of the disease. Density and Concentration of Baseball Teams, 1952 & 2007 Fig. 1-19: The changing distribution of North American baseball teams illustrates the differences between density and concentration. U.S. Baseball Teams, 1952 Fig. 1-19: Baseball teams were highly concentrated in the Northeast and Midwest in 1952. U.S. Baseball Teams, 2007 Fig. 1-19: By 2007, U.S. baseball teams were much more dispersed than in 1952, and their number and density at a national level had increased. Diffusion • “process by which molecules travel from a higher concentration to a lower concentration” TYPES OF DIFFUSION • Expansion Diffusion – idea or innovation spreads outward from the hearth • Contagious – spreads adjacently + rapidly • Hierarchical – spreads to most linked people or places first. • Stimulus – idea promote a local experiment or change in the way people do things. * Relocation Diffusion – spread of an idea through physical movement of people from one place to another Expansion Diffusion •Contagious •Hierarchical •Stimulus Relocation Diffusion Stimulus Diffusion Because Hindus believe cows are holy, cows often roam the streets in villages and towns. The McDonalds restaurants in India feature veggie burgers. Example of Relocation Diffusion Paris, France Kenya Photo credit: H.J. de Blij Photo credit: A.B. Murphy HEARTH * The source area of any innovation. The source area from which an idea, crop, artifact, or good is diffused to other areas. Old Approaches to Human-Environment Questions: • Environmental Determinism --> physical environment causes social development - has been rejected by almost all geographers • Possibilism physical environment limits human actions, but that people have the ability to adjust to the physical environment - less accepted today New Approaches to Human-Environment Questions: • Cultural ecology explores the relationship between a given society and its natural environment • Political ecology studies how political, economic, and social factors affect environmental issues.
