Map Elements

Scale •inappropriate for small-scale maps•not needed for familiar large-scale maps

Direction Indicator•north arrow - only for unusual orientations on large-scale maps

•use geographic grid on small-scale maps

Map Scales

GIS 27

Dimensionless Map Scales

•ratio that relates a unit of measure on a map to some number of the same units of measure on the earth's surface

•1:25,000•tells us that 1 unit of measure = 25,000 of the same units on the earth's surface

•1” on the map = 25,000 inches on the earth's surface

•one meter or one yard or one kilometer or one mile would represent 25,000 meters or yards or kilometers or miles, respectively, on the earth's surface.


GIS 28

Large and Small Scale Maps

1:5,000 is large scale

1:50,000,000 is small scale
