Map projections and Types of Maps

APHG 1.1

absolute direction, distance and location

the exact direction something is in, the exact distance something is from something else, the exact location of something

Goode Homolosine

Maintains true size and shape distortes map edges, bad direction. Looks like zigzag

Fuller

land is uninterrupted but has no cardinal direction and distorts the farther away from the centerpoint you go. looks like origami

Robinson

majority of distortion at poles, but maintains true size and shape

Winkel tripel

similar to robinson, but has a round look and is stretched at the sides, spreads distortion throughout map but poles are very distorted

Reference maps

informational, shows boundaries, names and geographic features

Thematic maps

shows data using different themes

Choropleth

map that uses color to show data

isoline

map that connects lines of similar data, often used for weather

Graduated symbol

uses symbols of different sizes to show data

Cartogram

changes the size of countries to show data of how much/little one country has/does/uses etc.

Gall - Peters

one of the most accurate for true size, alot of distortion in shape and direction, stretched vertically (peter)

Small scale

world, europe, asia, there is a small scale (small zoom) so it doesnt see all the details

large scale

cities, neighbourhoods, waterpark, lots of details

Relative direction, distance, location

where something is based on surroundings, the approximate distance something is from something else, something’s location based on surroundings

Mollewiede

distorts the shape and angle, but has the correct sizes, looks very horizontally stretched

Azimuthal

Shape and distance distorts as you get farther from the north pole, looks like a birds eye view

Meridians

arcs drawn between North and South poles (longitude)  Prime meridian - passes through England, vertical line 

International Date line

opposite the prime Meridan, and is super wonky and squiggly, vertical 

Parallels

Circles drawn around the globe, parallel to the equator (latitude) (like a ladder)

(0,0)

this is the point where the prime meridian and equator cross

GMT

local time in greenwich, which used to be a standard now replaced by the unviersal time

Time Zones

Earth is divided into 360 of longitude. Divide 360 by 24 time zones (one for each hour of the day) each 15 band of longitude is assigned to a standard time zone. 

GIS

geo info science, satellites orbiting the earth to analyze data about earth. Uses layering to  harvest data and show connections. 

GPS

global positioning system, helps with directions,tracking stations to locate at least 4 satellites and calculate the distance between them to find your precise location.
