generalization and scale

generalization

changes in geographic visualization depending on level of specificity

generalization related to _ model

power-knowledge

maps with small scales are not

shrunk versions of larger scale maps, just altered to only highlight important features

how to display terrain forms

colours, individual depictions, hatching, or shading

shading used on

dufour swiss topographic map, based on artificial sun shining from the northwest

contour lines

lines projected on a map that connect points of the same elevation above sea level, running horizontally and following relief’s indents and protrusions

base of a number label for contour lines always

points towards the valley

steeper slopes means contour lines are

closer together

a superelevation of x is

units of length/units of height

superelevation relates

scales of length and elevation so mountain doesn’t look too flat

which displays of terrain forms are preferred for medium to small scale

hatching, shading, and colour hues

which displays of terrain forms are preferred for larger and medium scale

contour lines and individual depictions

slope inclination and gradient can be represented as

the angle, aspect ratio (elevation: horizontal distance), percentage or per distance e.g. how many meters ascended per 100 meters horizontally
