Why does every map have distortion?
Because you can’t really take a 3D object and perfectly apply it to a flat surface
A few Projections in APHUG
Mercator Map projection
(Greenland is bigger than Africa)
Excellent at showing accurate direction, but HUGE errors in the size of landmaps (Greenland is bigger than Africa)
A few Projections in APHUG
Goode Homolisine projection
(Accurate in landmass ONLY)
Equal area projection. Shows the true size and shape of land masses, but has distortion near the edges of the map
A few Projections in APHUG
Robinson Projection
Has more distortion near the top center which preserves the side and shape but ends up spreading distortion everywhere
A few Projections in APHUG
Gall Peters projection
(distortion with land mass and d…)
One of the more “accurate” projections but has significant distortion with land mass and direction
What are the 2 categories of maps??
Reference and Thematic
What is a:
Reference Map?
(An informational map that shows …, names of places, and … features of an area)
An informational map that shows boundaries, names of places, and geographic features of an area
What is a:
Thematic Map?
(A map that displays … patterns/places and uses … data to display specific topics)
A map that displays spatial patterns or places and uses measuring data to display specific topics
What is one way geographers collect data?
Remote sensing
What does the info from remote sensing help us with?
It helps us better understand changes over time
What are the 3 geospatial technologies
GIS, GPS, and Remost sensing
What do the 3 geospatial technologies do?
They help businesses and organizations locate places and visualize geographic data
What does Photo Analysis help geographers with?
It helps geographers better understand changes to an area and can show the impact humans gave there
What is
Photo Analysis?
(Looking at a … and analyzing different …s of it)
Looking at a photo and analyzing different elements of it
What do governments use population data for?
They use it to determine the services needed.
If the population is very young for example, then there would be more funding for schools
What is:
Absolute Location?
The EXACT spot on the earth’s surface
(It’s kind of like (x,y) on a graph in math but uses N north and W west)
What is:
Relative Location?
The position of a place compared to another
An example of this would be describing your location using the buildings around you
What are:
Physical Chracteristics?
Things like rivers, mountains, and climate
What are:
Human characteristics?
Things like language, religion, and population
What do BOTH characteristics provide?
(Physical and Human characteristics btw)
A sense of place
What happens when we observe spatial patterns?
We get a better understanding of the flows there.
For example, the way school desks are arranged. If the desks are in a grid you’re more likely to pay attention to lessons while writing notes, but if they’re clustered you’re more likely to have interactions with your peers and group activities
What are the 3 main types of regions?
Formal, Nodal, and Vernacular
What is a:
Formal Region?
(Also known as Uniform or Homogenous)
(An area in which … shares in common … or more distinctive …s)
An area in which everyone shares in common one or more distinctive characteristics
What is a:
Nodal Region?
(Also called Functional)
An area organized around a node or focal point
(The characteristic choosen to define these regions dominate at a central focus or node and diminish in importance outward)
TV stations are an example of this, because when yu get farther away from the city of the station, the station starts to get blurry and eventually makes a fuzzy noise only
