Human Geography Flashcards
What is Human Geography?
- Geo + graphie = literally “writing about” or “describing” the earth.
- Tries to describe spatial patterns and identify their underlying causes.
- Concerned with patterns and processes of human phenomena -development/expansion of settlements, food production, patterns of cultural activity, population changes and geopolitical relations
Human Geography
- Textbook Definition
The study of patterns and processes of the earth’s human or social environments, including population change, economies, cultures, politics, settlements, and human interactions with the natural environment.
Definiton - Related to 3 Questions
Where? - Descriptive location of place
Why there? - Underlying causes as to why it is done there.
Why care? - Why is it beneficial? Est. moral theories for making a value judgement of human activities.

Geographical Perspective Explained
Human Geog broke into subdisciplines: population, economic, culture, etc.
- What unifies all disciplines is the concern about how things vary across the earth surface.
- How is pop distributed, how do economic activities vary?
- Approach to answering these questions is called geographical perspective.
- Geographers view phenomena and think about their spatial distribution (understanding change over space)
Geographic Concepts
Every discipline useds simple terms in specialized ways.
- Space
- Place
- Region
Space
- Definition
- Two types
The ariel extent of something on earths surface.
- Geopgraphers measure space in two ways - absolute space and relative space.
Absolute Space
Amount of space that can be measures with definable boundaries
- How big is Lethbridge?
- Mathematical accurate
- Home property boundaries
- Country borders
- Property lines are fixed and areal extent of property is not open to interpretation.
- Can be measured in Square units or hectares.
Relative/Perceptual Space
Subjective and based on a persons perception.
- Perception is based on knowledge and experience.
- Golf - hole is far away for beginners, but not pros.
Mental Maps
An image of the way space is organized influenced by an individuals knowledge or experience in that space.
- Mental map based on our perception
- Map of Lethbridge would be different for everyone.
Scales
Global Vs. Local
A study area in the context of the whole earth.
Global: Area being studied closely approximates the entire earth
Local: Focus is on small protion of the earth such as a country or region.
Location
- Definition
- Two Types
Specific space that does not change.
- Absolute and relative
Location
- Absolute Locations
- Use system of reference points to identify a precise location
- Constant between observers as it is pinpointed on global grid system (long and latit)
Location
- Relative Location
Location of a certain place determined by location of other places.
- Varies with observer
I.E. Where is Edmonton?
- 300 km North of Calgary
- 50 bucks in gas
Location
- Nominal/Toponym Location
Nominal: Refer to a location by its common name.
Toponyms = common name. Associated with particular places and reflects the culture of the individuals naming them, the place itself, and its characteristics
- Lethbridge is the name of a few places, but we think of our city. It has different meaning to us.
Two key Components of Location
- Site and Situation
Site: Internal physical characteristics of a location - climate, topography and elevation.
Situation: external connections between a location and other locations.
- Thinking about a city based on its strategic location. I.E. Calgary - is an oil location.
Place
A specifial location
Has acquired particular meaning or significance.
- It is considered a place if it has meaning to me, but to someone else who has no attachment to it, it is simply a location.
Raymond - has meaning to me so it is a place and not a location.
Place
- Sense of Place
Builds on definiton of place
- feelings evoked by a place such as home, that result from experiences there.
- Feelings positive or negative
Place
- Sacred Places
- Placelessness
Sites that are significant for religious, political, or other reasons, to an individual or group.
Places we encounter daily and have no meaning to us.
- Fail to prodeuce sense of community.
- They are standardized/homogenous
- Fast food places
- Box stores
Region
Area defined by shared characteristics
- Cultural
- physical
- combination of both.
Regionalization
Subdividing large areas into several smaller regions
- Usually involves generalized statements - the prairies, rocky mountains, the north.
Types of Regions
- Formal (uniform) regions
- Functional (nodal) regions
- Vernacular (perceptual) regions
Formal (Uniform) Regions
A region that has shared characteristics.
Physical: prairies
Politcal: Cons
Functional (Nodal) Regions
A region organized around a node or focal point, and unified by specific economic, political, or social activity.
- Has a shared function
Further away from that node the less important it is.
- Church - many people in the area will worship there, but its importance dwindles the further away you get.
Vernacular (Perceptual) Region
Shared perception of area.
Defined by cultural identity of a group and sense of place.
Raymond - LDS church culture
Landscape
- Physical
- Cultural
Visible characteristics
- Can be physical or cultural
- Physical - rocky mountains
- Cultural - modifications to the land made by humans.
Distance
- Absolute
- Relative
Space between two entities
Two Units
- Absolute: Physical distance (Km)
- Relative: Experience - time, cost, psychologocal, or social.
Concepts: Interaction, Communication, and Movement
Space, place, location and region all refer to the earths surface.
But human Geographers also interested in people and places and these concepts build our understanding of how people inhabit the places they do.
- Distribution, Diffusion and Interaction
Distribution
Patterns identified through varying distances between objects.
Three components:
- density: How often phenomena exists
- concentration: phenomena clustered/dispersed - car lots
- pattern: spatial arrangements - houses in patterns.
Diffusion and Interaction
Two concepts used to understand connections between people and places.
Diffusion
Spatial connections through spread and growth.
- Reps one way change occurs
Cultural Diffusion
- Relocation
- Expansion
Where an idea or innovation spreads from its source to other places.
Relocation
- People move and physically take phenomena with them.
Expansion
- Spread of culture without individual movement.
Expansion Diffusion occurs Via:
Contagious
Hierarchial
Contagious
- Similar to disease
- greater # of contacts and closer people are the faster it spreads.
Hierarchial
- Through key people or places first.
- Music
Interaction (Spatial)
Space affects interaction.
- Through distance between locations
- Through site qualities.
Distance
- Toblers First Law of Geog
“everything is related to everything else, but near things are more related than distant things”
Interaction Cont.
-Distance Decay
The effects of distance on spatial interaction.
- The further we have to travel for something, the less likely we are to do so.
- Buying groceries
Friction of Distance
The effect of distance is not static
Affected by technology, other factors
- Cars, communication, money
Site Qualities
- Accessibility
- Connectivity
While distance influences where you go, so does accessibility and connectivity.
Accessibility
- Ease with which a location can be reached.
Connectivity
- Direct and indirect linkages between two places.
- Phones, cars, trains.
Geographical Tools (2)
Two distinct tools
1. Maps: gather, convey, and analyze spatial information.
2. Recent Geomatics Technologies: Enhance gathering, conveying, and analyzing practices.
Geographical Tools
- Maps
- Cartography
- Used for 8000 yrs - clay tablets in Turkey
- 3000 yrs. ago Greeks advenced mapping techniques.
- Use visual techniques
Cart: The art and science of map making. Used info from surveryors until 1960s. Now maps done digitally.
Global Grid
Needed to make maps
- Two arc systems created a grid across earths surface.
- Arcs of latitude and longitude.
- Absolute location for any point on earth can be described using this grid system.
Global Grid
- Acrs of Latitude
Run horizontal scross the earth
- Best known line is the equator
- Called parallels because each line repping a different degree of latitude, runs parallel to the others.
- Parallels measured as angles form earths centre.
Global Grid
- Arcs of Longitude
- Run perpendicular to lines of latitude which are meridians that connect at the two poles.
- Best known line is prime meridian which reps 0 degrees.
- Arcs measured as angles from the earths axis.
Global Grid
- Time Zones
Created in 19th century to co-ordinate international movement (trains).
- Help create shipping times and keeping time.
- 24 zones of 15 degrees (sun passes 15 degrees of longitude every hr).
- Zones also created politically and socially.
Map Scale
- Large Vs. Small
All maps are scaled models of the earth
Scale relates map distance to absolute distance.
- Large scale maps show small areas with less info - world map
- Small scale maps show lots of info - city maps
Map Projection
Required to convert 3 dimensional space onto 2 dimensional images.
- Different projections for different needs
- Distort size, shape and distance of space
Mercator projection and navigation
- Planar projections
- Conic projections
- Cylindrical projections
Map Forms and Types
- Reference Maps
Designed to illustrate locations such as towns, cities, and buildings.
- Combine coordinate systems (lat/long) as needed to plot locations or navigate.
- Road maps and transit routes
Map Forms and Types
- Thematic Maps
Designed to illustarte analysis.
- Illustrate patterns or trends
- Political voting maps
Thematic Maps
- Four Types
Map type depends on the information being presented and the message the map is intended to convey.
1. Dot Maps
2. Choropleth Map
3. Isoline Map
4. Cartograms
Thematic Maps
- Dot Map
Each dot reps an occurance of the phenomena being mapped.
- Maps that show cases of illness and disease within a town
- Sport maps on history of goals.
Thematic Maps
- Choropleth Map
Uses colour or shading to indicate differences in an area.
- People per km
Thematic Maps
- Isoline Map
Lines that link points with the same measurement.
- Maps of mountiains from above that have lines that show elevation.
Thematic Maps
- Cartograms
The size and shape of space is distorted to emphasize the attributes being mapped.
- Difference indicated by distortion of area size.
- Area of provinces distorted to demonstrate its share of the population.
Spatial Analysis and Geomatics Technologies
Used to obtain data for map making.
- Previously used information from surveys and people.
Geomatics Include Four Technologies
- Remote sensing
- Computer – assisted cartography
- Global positioning systems (GPS)
- Geographic information systems (GIS)
Remote Sensing
Obtaining spatial data using both photographic and non-photographic sensor systems to monitor the earth and its surface features from a distance
- Conventional camrera used until the 1960s.
- Now we have satellites and drones
- Satellites measure electromagnetic radiation.
- Internet and Google images also aid in info gathering from a distance.
Computer Assisted Cartography
AKA
Digital Mapping
- Previoulsy we drew things on paper and sent it to the printer.
- Now done via computer
- Can create, amend and update info
- Create map features
- Loss of drafting skills, but still need to design.
Global Positioning System
(GPS)
- What is it and Controversies
Satellite system used to determine the absolute location.
- GPS devices and phones detect signals from satellites and give us our exact location and elevation.
Controversies
- Daily activity with digital maps are a participatory process. Meaning our devices gather info while we use them - driving habits for apps.
- Privacy and permission issues
-
Geographic Information System (GIS)
Computer-based tool that captures, stores, displays, analyzes, and maps large volumes of spatially referenced data.
- geographers combine multiple layers of spatial data to reveal spatial distributions and patterns, and to uncover spatial processes (population growth). All in one digital map.
- Example on page 33 of text about creating an urban map.
People and Places
- How to understadnd interactions
Human geography is all about studying people and places and the interactions between the two.
- One way to understand this interaction is through building your geographical “awareness”.
- No specific formula to do this.
- Know key places and something about them.
- Think about connections and how will these key places affect other locations?
- Ukraine issue or China issue with COVID
Demography
Studies (3)
The science that studies
- Population size and composition (Age, sex)
- The processes influencing population change (fertility, mortality)
- The links between populations and the larger human environments they are part of.
Population Distribution
Refers to where people are located and in what numbers.
- key concern of human geography.
- Info found through census
Population Distribution
- Three key elements
- Three Factors
Elements
1. Concentration - populations clustered or dispersed.
2. Density - why do more live in one area than another?
3. Pattern - No idea
Three Factors
1. Physical - Climate, water, soil
2. Cultural - History, migration, religion
3. Economic - politics, jobs, living cost.
Distribution or World Population
People prefer living in certain places more than others, and these preferences are linked to both human and physical geographic factors.
Dist of World Pop
- Three areas of historic concentration
- South-Central Asia clustered along key rivers and coasts
- East Asia clustered toward east coast along rivers, disperses to west.
- Europe (including Russia) clustered toward west and along rivers, relatively more urban.
Other Regional Patterns/Trends
- Growth in Afrcia and South Asia
- China pop will decline by 2050
- Nigeria will double in pop: fertility, better healthcare.
- Disease will affect populations
- See effect on death rates in the future due to COVID
