Presenting Maps and Data

GIS 11

Presenting Maps and Data•Showing data to the general public should be simple and easy to read•Know your data

GIS 12

Presenting Maps and Data Population

GIS 13

Presenting Maps and Data Population per Square Mile

Map Layouts

GIS 15

ArcView Layouts

GIS 16

Printed Map Layouts

Concise Title•topic, place, time

Legend•Word “Legend” or “Key” not needed

Data Source•Source and date data was obtained

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 23

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.
