Cylindrical

Homolosine

Map Projection Cont. •Homolosine-shows accurate shapes and sizes of the landmasses, distances not correct

•Robinson-shows entire earth, landmass near the poles look flat

Map Projection Cont.

Thematic Qualitative map(colors symbols or lines

to show patterns)Thematic Flow-line map

Thematic CartogramBased on data not land

Cartographers: Gather Data by

Surveying

What:elevation,vegi-

tation & climate

Tools

How:Satellites:

LAND SAT. & GOES

GISGPS

Step 1 in making map

theodolite

How much detail?Map Scale

Ratio scaleEx:1:30,000,000

Bar scale

Small Scale-Large area

without a lot of detail

Large Scale-show a small

area with much more

detail

Step 2

Projections

Planar/Azimuthal-give the shortest distance between two places. Very

distorted

Cylindrical-shows earth on map

Conical-Used to show large area,

shows shape accurately, but

distorts landmass on edge

Step 3

Mercator-shapes of the continents are distorted and compared near

the equator

Homolosine-shows accurate shapes and

sizes of the landmasses, distances not correct

Robinson-shows entire earth,

landmass near the poles look

flat

Type of Map

Political-shows boundaries

Theme-focus on specific type of

information patterns,

movement, data

Physical-types of landforms &

bodies of water
