Maps and Demographics Flashcards
Symbolic representation fo all or part of the globe
map
every map should have…
- title
- scale bar
- compass rose
- map key/legend
tells you what the map is about
title
tells you how to transfer distance on a map to actual distance
scale bar
tells you which direction is north
compass rose
tells us what symbols mean on a map
map key/legend
objective location on a map
absolute location
subject or in relation to
relative location
political map
- has man made things(country boundaries)
- different colors
- different political divisions
physical map
- focused on physical properties(terrain mountains)
- topography(elevation changes)
thematic map
- has specific kind of information(ex. pictures of stuff exported)
- qualitative: what quality does the country have
- quantitative: numbers in a map
flowline map
- ex. immigration of different ethnic groups
- things moving from one place to another
- thickness of arrow indicates quantity
what are topographic maps also known as?
contour maps
topographic maps illustrate…
the elevation above sea level using contour lines
what does the gap between the contour lines stand for on a topographic map?
change in elevation: when there is a circle with no line it is the top
(closer line, steeper hill)
connects points of equal elevation on a topographic map and shows the elevation and the shape of the land
contour line
the difference in elevation between each contour line
contour interval
every fifth line is darker and has an elevation printed on it
index contours
rules of contour lines
- they will never cross each other
- contour lines always form closed loops even if not shown on a map
- bend upstream when crossing a river
- maximum possible elevation for a hill is one less than the value that would have designed the next contour line.
a crater or sinkhole are represented by dashed lines, hachure marks, on the inside of a contour line
depressions
locations whose exact elevation is know and is noted on a barass or aluminium plate and is indicated on maps with an x followed by a BM
benchmarks
indicates the distance on the map compared to distance in the real world
map scale
the study of populations of various categories
demogrpahics
way of life of a people who share similar values of beliefs
