Mapping Basics
• Map: a model on a flat surface– Early Explorers made maps by hand=cartographer– Today, pictures from satellites

Items Found on a Map
• Numbers for location= Latitude Longitude
• Scale
• Compass Rose
• Key/Legend

Types of Maps1. Road Maps2. Political Maps- shows city, state, country
boundaries3. Topographic Maps-used by
Geologists/Outdoorsman

Topographic Maps
• Topography Map: Provides info. On elevation, relief, and slope of the surface– Puts a 3D landform such as Mtn. onto 2D flat
surface=map

Terms Used on Topographic Maps
• Contour Line: Connects points of equal elevation ex. Hill/Mtn.

• Contour Interval Rules1. The closer the lines=steeper it is2. The further apart the lines=flatter area3. The contour interval must stay the same on each
map
