AP HUG VOCAB UNIT 1 Flashcards
Map
a representation of an area of land or sea showing physical features, cities, roads, etc.
cartographer
a person who makes maps
data aggregation
the compiling of information from databases with intent to prepare combined datasets for data processing
spatial patterns
the placement or arrangement of objects on Earth’s surface; also includes the space between those objects
spatial perspective
identify use of space
reference maps
a map that shows geographic locations on Earth’s surface, such as the locations of cities or oceans
thematic maps
a map that emphasizes the spatial patterns of geographic statistics or attributes, and sometimes the relationships between them
absolute distance
the distance that can be measured with a standard unit of length, such as a foot, yard, mile, or kilometer
relative distance
shows similarity despite absolute location
clustered
when things on a map are grouped together, like data
dispersed
when things like data on a map are spread out
map projections
a method for representing the surface of Earth or a celestial sphere on a plane (two-dimensional) surface; all map projections distort some aspect of Earth’s surface
distortion
he alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation
Mercator projection
a map projection that is useful for navigation because the lines connecting points on the map represent the true compass direction; however, landmasses become increasingly distorted the farther away they are from the equator
Peters Projection
a map projection that shows all landmasses with their true areas but distorts their shapes
Goode projection
a map projection that avoids shape distortion and the restrictions of a rectangular map by creating “interruptions” in the map’s continuity; in each section, map projection regions are shown “equally”, like an orange peel being laid out in a flat surface
Robinson Projection
a map projection that attempts to create the most visually appealing representation of Earth by keeping all types of distortion relatively low over most of the map
census
an official court or survey of a population, typically recording various details about individuals, such as age, sex, and race
fieldwork
learning and doing research involving first hand experience, which takes place outside the classroom setting
absolute location
a precise position on Earth’s surface
latitude (lines)
the (invisible) horizontal lines circling Earth parallel to the equator; latitude is the degree of distance north or south from the equator, which is at 0 degrees, as far as the poles, which are at 90 degrees
longitude (lines)
The (invisible) vertical lines on Earth’s surface that mark imaginary circles connecting the North Pole with the South Pole
equator
an imaginary line around the middle of a planet or other celestial body. It is halfway between the north pole and the south pole, at 0 degrees latitude.
prime meridian
the zero degree longitude line that runs through Greenwich, England; also known as the Greenwich Meridian
Global Positioning System (GPS)
a system of 24 satellites that orbit Earth twice daily and transmit radio signals Earthward; the basis for many map-based apps that provide directions on how to get from one place to another
