Maps are Models of....
the earth's surface
Why do we make maps?
To know the positions of things on the face of the earth and how they relate to one another.
The scale of a map determines what
the ratio of a distance on the map to the corresponding distance on the ground.
Large Scale maps
show small areas in greater detail
Small Scale maps
Show large areas in less detail
Maps use artificial landmarks for what purpose
to locate features.
Flat maps show a what view of the earth's spherical surface
a distorted view.
Name three standard features of a map
Map Scale, a map Legend, and a North Arrow
Map projections are ways to
transfer details from the earth's surface to a flat mapping surface
Name the three geometric map projections
gnomonic, cylindrical and conic
Standard maps can be
geographic, topographic or political
Thematic maps show
particular themes or subjects
Geographic Information System (GIS)
Technology that greatly improves the ability of maps to reveal unsuspected relationships among different kinds of data
Before modern navigation methods, such as GPS, how did sailors find their longitude?
To find their longitude, sailors used a seagoing clock to indicate the difference in time between a location at a known longitude and the local solar time at their location
Which standard map would show glaciers and lakes?
A geographic map.
Why are thematic maps useful?
They show spatial relationships among similar kinds of data that may not have geographic significance by themselves.
True or False: Do maps usually use an oblique view to show as much of the earth's surface?
False. The oblique view distorts distances.
True or False: North, south, east, west are always the same, no matter where you are on Earth.
True
True or False: Map projections can show the true shape of countries and their true sizes
False. All map projections can show the true shape of countries and their true sizes.
True or False: The terms gnomonic, cylindrical, and conic refer to the shapes of the projection surfaces for each kind of projection.
False. All map projections involve distortions of some type. None can show both true shape and correct size relationships.
True or False: The steepness of a slope on a topographic map is indicated by the angle a contour makes with the horizontal.
False. The steepness of a slope on a topographical map is indicated by the space between contour lines.
True or False: A map that shows the location of all the geysers in Yellowstone National Park is a thematic map?
True
