Title
-Describes what the map shows (place, time
period, etc.)
10
Orientation
• -refers to directions? shown by compass rose
• cardinal directions N, S, E, W
• intermediate directions NW, NE, SW, SE
• must have at least North

11
Date Author
-helps us judge accuracy of the map Date tells
us how up-to-date info. is Author is this
person reliable?
Date usually down here, too
12
Legend
-tells us what each symbol or color represents
13
Scale
-shows relationship between map measurements
and actual distances
14
Index
-alphabetical list of places shown on a gridded
map or set of maps (gives addresses of places
listed) Always on back of map
15
Grid
-Set of intersecting lines that determine
absolute location Can be letter/number (city
map) Typically latitude longitude
16
Source
-used if information not obtained by direct
experience or observation (gives us reliability
as well)
17
Surrounding Places
-identifies places or features that border the
area depicted on a map (relative location)
