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 Maps 1.Road Maps 2.Political Maps- shows city, state, country boundaries 3.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 ft 3000 ft 2000 ft

Dashed Contour Line ex. Valley/Depression 3000 ft ft.

Ex. Connect the dots of the same elevation 3000 ft 2500 ft 3000 ft 2500 ft 2100 ft LV

Ex. Connect the dots of the same elevation 3000 ft 2500 ft 3000 ft 2500 ft 2100 ft LV

Contour Interval Contour Interval: numerical difference between contour lines 80 ft 60 ft 40 ft 20 ft C.I= C.I.

Contour Interval Rules 1.The closer the lines=steeper it is 2.The further apart the lines=flatter area 3.The contour interval must stay the same on each map
