Chapter 1 Flashcards
Abiotic
composed of non living or inorganic matter
Acculturation
process where an ethnic group is absorbed into a larger society while retaining aspects of distinct identity
Do everything of new culture but keep their cultural traditions- my family
What is the word geography based on?
invented by Greek Erastosthenes
on two Greek words
Geo means “Earth” and “graphy” means “to write”
How do geography and history differ?
a geographer can go to the place
Areal differentiation
geographers look at where things occur, why they are there and how things differ from place to place
Spatial analysis
way to analyze data which includes information about location of places and characteristics, allows for examining spatial attributes of earths surface
Human geographers ask?
“Where are people and activities found on Earth?” and “Why are they there?”
ex- what languages are spoken in Manitoba
what language characteristics vary from place to place
(french spoken in Manitoba vs french spoken in France/ Quebec)
Summarize geography’s five most basic concepts
place region scale space connection
place
is a specific point on Earth distinguished by a particular characteristic.
Each place occupies a unique location or position
region
is an area of Earth distinguished by a particular characteristic
What do geographers use to explain why every place is unique?
place and region
What do geographers use to explain why different places are interrelated?
scale
space
connection
What are the 3 types of regions?
Formal- share a common feature
Functional- defined by activity
Perceptual- ideas we have abt what constitues a region
Ex- canadian praries
Scale
is the relationship between the portion of Earth being studied and Earth as a whole
Geographers are concerned abt global scale
Space
refers to the physical gap or interval between two objects
Not outer space
Connection
refers to relationships among people and objects across the barrier of space
Concerned abt various means through which connections occur
Specially interested between connections of human activity and physical space
Absolute Location
A precise system of locating phenomena in space (e.g. latitude and longitude)- mathematical location
Provides unique description of location
Describes on point on earths surafce
Specific address
Relative Location
The position of a place or activity in relation to other places or activities- sometimes carries social
Neither precise or unique
Can change over time
Ex- winnipeg is located in southern manitoba
780 km southeast of Saskatoon, a little over 215 km east of Brandon and just over 100 km north of the US border- describing winnipeg in terms of other places location
Absolute Direction
non-culture bound(isnt subject to change in different areas), based on the cardinal, or compass, points (e.g. Saskatoon is northwest of Winnipeg and southeast of Edmonton)
Relative Direction
culturally dependent and vary by location (e.g. does Winnipeg truly belong in the West or is it something else? Is La Ronge, Saskatchewan, in the North, or near the North?)
Absolute Distance
absolute spatial separation between two places (i.e. 400 KM)
Relative Distance
non-absolute measurements of separation between places
e.g. eight hours from Winnipeg to Saskatoon)
Cartography
is the science of mapmaking
Reference maps
Show locations of places and geographic features
Use absolute locations
Can be used for a variety of purposes
Look up roads and rivers
Thematic maps
Tell a story about the degree of an attribute, the pattern of its distribution, or its movement
Used for one specifc reason
Ex- where a specific langauge is spoken, identify rain patterns, income globally
Proportional symbol/ graduated circle
Uses different sizes of shape to represent quantity of the theme
All maps show population
Problem is you cant see location largest of cities- we don’t know exactly which county the circle covers
Dot maps
represent the theme
Each dot represents a particular amount
Density is represented by density of dot
In legend the dots are all the same size
Isopleth maps
use lines to get averages for an area
Temp and elevation
Contour map uses these lines
If a contour shows ll lines at 50 m and joins them up the line represents all points at 50 m
Chloropleth maps
shade areas to represent numerical data by the intensity of the colour
Differ from isopleth bc Use predetermined areas
U can tell if it’s this type of map bc every state country will be shaded in according to boundary
Cartogram
maps with areas scaled to show some other value than shear size
GIS, what are the limitations
: Geographic Information System
a collection of computer hardware and software that permits storage and analysis of layers of spatial data
Very versatile- form and function are based on what is being studied
Only limitation is data must have some spatial characteristic
Data must have some attribute that can be located in space
Spatial coordinate value- latitude or longitude, postal code
photogrammetry
the science of taking measurements of Earths surface from photographs
remote sensing
the acquisition of data about Earths surface from a satellite orbiting Earth or from other long distance method
Vector data
uses coordinates to identify points, paths and boundaries of polygons- represent real world data
Raster data
uses pixels or cells to store information
Attribute data
data associate with the map but doesn’t appear on it
Info stored on the GIS but doesn’t visually appear on map produced
Includes stats values names and qualitative attributes
Qualitative data
In depth answers and responses from open ended question
i.e. Tell me about your quality of life in Winnipeg. What makes it good or bad?
Advantage is it provides info abt human behavior emotions or personality characteristics
Quantitative data
Test and verify hypothesis and develop models
Numerical or “count data”
How good is your quality of life (QOL) in Winnipeg?
1 = poor QOL,…, 5 = excellent QOL
Advantage is it can be put all together and used for statistical analysis
/
Quantitative research requires the standardization of data collection to allow statistical comparison, but qualitative research requires flexibility, allowing you to respond to the interviewee during the research process. Qualitative research is very time consuming, particularly when entering and analyzing the data.
GPS
a system that determines the precise location of something on Earth
geotagging
identification and storage of a piece of info by its precise latitude and longitude coordinates
VGI
volunteered geographic info
the creation and dissemination of geographic data contributed voluntarily and for free by individuals
citizen science
scientific research by amaateur scientists
PGIS
participatory GIS
community based mapping representing local knowledge and info
mashup
is a map that overlays data from one source on top of a map provided by a mapping service
Mental Maps
Personal representation of a part of the Earth’s surface
maps we carry in our minds of places we have been and places we have heard of
landmarks, paths, parks, “happy places”, “scary places”, etc
terra incognita,
unknown lands that are off limits
Activity Spaces
the places we travel to routinely in our rounds of daily activity
Most detailed and well known part of mental map
what 2 decisions must a cartographer make to make a map?
scale and projection
Scale: Interpreting Maps
is the spatial extent of something
Things found at once scale are being influenced by what is happening at a different scale
Ex- federal government can create policy affecting timber prices and change the amount of forestry or close down timber mills affecting ppl in community
gives us a way of showing (in reduced form), all or part of the world (cartographic, or map, scale)
observational scale
the observations we make and the context we see varies across scales, such as:
- local - regional - national - global
map scale
which is the relationship of a feature’s size on a map to its actual size on Earth.
What does a scale of 1:10,000 mean?
Everything on map is one ten thousandths of its size in real life
Map scale is unitless
1 mm on map = 10000 mm on ground
projection
Transferring locations on Earth’s surface to a flat map
Mercator Projection
shows accurate shape of continents but distorts size particularly in high latitudes near the poles
Created in 1569
What google maps uses
Generally preserves shape of country- makes close up of cities accurate
Original purpose was navigation- direction
Was designed that if a line was drawn between 2 places on a map it would provide exact angle on the compass
Size of countries is distorted
Distortion shows imperialist attitude of European domination over southern hemisphere
