small scale map

1:600 000 or greater

shows a large area with less detail

(____ scale because you are not zooming in that much)

eg. atlas maps on continents

medium scale map

btwn 1:75 000 - 1:600 000

shows moderate area in moderate detail

large scale map

less than 1:75 000

shows small area in great detail

(you are zooming in a ton)

eg. map of surrey

topographic map

shows three dimensional aspects of an area, such as elevation through the use of contour lines

planimetric map

shows the two-dimensional layout of an area, through vertical and horizontal distance

define scale

the relationship between the distance on a map and the actual distance on the ground

3 types of scale (give examples)

Verbal scale: 1 cm represents 4 km

Linear scale: see photo

Representative Fraction: 1: 400 000

magnetic declination

the angle between the physical north pole and the magnetic north pole

3 ways to calculate gradient

m/km (include negative if slope points down! m = vertical distance, km = horizontal distance)

% (must have same units on top & bottom of fraction)

ratio (round to 1 decimal place, must have the first number be 1)
