chap 1 : what is human geog Flashcards
geography focuses on what?
interaction of ppl and places
diff between physical and human geog?
phys: Severe weather, landforms, earthquakes, and volcanoes, as
well as soil, plant, animal ecology
human: Development and expansion of urban and rural settlements,
food production, patterns of cultural activity, population
change, geopolitical relations
why think geographically?
-Enables a unique way of seeing the world
-Helps us understand complex problems
-Helps us see connections at a variety of scales
in ancient greeks, geo= ?
graphos = ?
the world , to write
2 distinct tools of geography?
- maps
- recent geomatics technologies (methods for collecting, analyzing, and interpreting geographic information, including GPS, GIS, and remote sensing.)
3 types of map scale:
written statement- ratio / fraction-
-graphic
small scale vs large scale?
Small scale (entire cities): Large areas
-Less detail
-ex: City 1:10,000
Large scale (1 building):
-small area
- more detail
-ex: building 1:1,000
There is an … number of possible projections
infinite
4 main “real world” properties we try to preserve
- shape : Conformal projections – Mercator
- distance: Equidistant projections
- size/ area : Equal Area projections – Gall-Peters
- direction: from one point to another- Azimuthal projections
some properties opt for compromise like which projection?
Gall’s projection
▸Mercator projection is …
conformal
standard world map projection used from 1600s to 1960s
when did Peters create his equal area projection?
1967
equidistant
Show true distances in
all directions from
one or two central
points
compromise:
sacrifice some or all properties to provide a more balanced view of the world
– Robinson projection (we use in this course)
– Gall’s (used in our atlas)
The grid system needed for what?
- navigation
- plotting location
- spherical earth
