Mapping Flashcards
definition of map
a map is a graphic representation of the earths surface, that is done to scale
a large scale map has..
large amount of detail
small area shown
a small scale map has..
small amount of detail
large area shown
physical features of a map includes…
mountains
bodies of water
deserts
hills
cultural features of a map includes…
railways
roads
buildings
bridges
a topographic map is?
a detailed accurate graphic representation of features that appear on earths surface
area referencing…
uses 4 letters
reads from bottom left
grid referencing…
uses 6 letters
when the location is too precise you use GR
square is divided in tenths
BOLTS stands for?

what are eastings and northings?
eastings - grid lines that run from north to south
northings - gird lines that run east to west
what is latitude?
- lines that run east to west across the earth
- equator 0* (important line)
- lat = flat
what is longitude
- lines that run north to south
- prime meridian
distance, time, speed formulas?
D = s/60 x t
T = d/s x 60
S = d/t x 60
what are the types of slopes?
- uniform slope (evenly spaced contour lines)
- concave (closely spaced at top, widely spaced at bottom)
- convex (widely spaced at top, closely spaced at bottom)
what is contour intervals?
the height difference between each line
what is site?
physical features
- e.g. contour lines
what is situation?
location
- e.g. latitude and longitude
- distance and direction from another place
steps of drawing a cross section?
- with a piece of paper, plot the distance of point A and B
- mark each contour line between them
- put into graph
- show designated cross section
finding gradient formula?
(rise/run)
(highest point-lowest point)/distance between points
what is topography?
the lie of the land
convert cm to km, measuring map to scale?
Acm X scale
divide answer by 1000
