Reference Maps - Answer✔What maps are used to display important physical elements of a
specific geographic area, such as countries, rivers, mountains? These maps store data and show
a variety of features for a variety of uses. They also focus on literal representation of a
geographic area
Thematic Maps - Answer✔What specialized maps are used to understand one particular
attribute or characteristic of a specific geographic area? Their chief goal is to focus the user's
attention on specific features or characteristics. Examples are population maps, weather maps,
and maps illustrating the spread of disease. They focus on demonstrating information about a
particular characteristic.
Analytical Map - Answer✔What maps use cartography techniques to uncover and learn about
patterns and trends in a specific geographic area? They are used to explore the role of location
and space to answer questions. The process of using cartography to discern some truth.
Literal Maps - Answer✔What maps are meant to show actual things and places? These maps
strive to display the objective truth about a specific geographic area.
Figurative Maps - Answer✔What maps show conceptual or imagined places?
These maps use symbols to represent a narrative or point of view; they are much less
concerned with physical accuracy than are literal maps.

Map Scale - Answer✔What shows the proportion of a given distance on a map to the
corresponding distance on the ground in the real world? This measures how much the features
of the world are reduced to fit on a map.
Representative Fractions - Answer✔What is the term for when map scale is shown as a ratio?
The most commonly used measure of map scale; ex: 1:24,000.
Cartesian Coordinate System - Answer✔What would you call a grid formed by putting together
two measurement scales, one horizontal (x) and one vertical (y)? This reference system is
named for the seventeenth-century mathematician and philosopher René Descartes.
Geographic Coordinate System - Answer✔What is the reference system devised to locate
particular places on the surface of the earth, using lines of latitude and longitude?
Longitude - Answer✔What imaginary lines run east to west? This is part of the geographic
coordinate system that's scale ranges from +180° to -180°.
Latitude - Answer✔What is the north-south scale, which ranges from +90° (or 90° N) at the
North Pole to -90° (or 90° S) at the South Pole? This is a set of imaginary north-south lines that
form part of the geographic coordinate system.
The Graticule - Answer✔What specifies positions on the globe with latitude and longitude
coordinates? This is the grid pattern in the geographic coordinate system.
Projection - Answer✔What is the term for turning a three-dimensional globe into a two-
dimensional map? This is a method of "flattening" a globe into a form that can be represented
on a flat surface.
Conformal Projections - Answer✔What type of projection preserves shape and angle, but
strongly distorts area in the process? For example (such as the Mercator projection), the shapes
of coastlines are accurate on all parts of the map, but countries near the poles appear much
larger relative to countries near the equator than they actually are.
