Unit 1 Flashcards
scale
Scale: The relationship between that being studied and the Earth as a whole.
Space
Space: Physical gap or interval between two objects.
Map
Map: A two-dimensional or flat-scale model of Earth’s surface, or a portion of it.
cartography
Cartography: the science of map-making
GIS
GIS: (Geographic Information System) captures, stores, queries, and displays the geographic data; a computer-based analysis tool.
Photogrammetry
Photogrammetry: the science of taking measurements of Earth’s surface from photographs.
Remote Sensing
Remote Sensing: the acquisition of data about Earth’s surface from a satellite orbiting Earth or to other long-distance methods.
GPS
GPS: (Global Positioning System) system that determines the precise position of something on Earth.
Geotagging
Geotagging: recorded locations of all the information we gather and photos we take with our electronic devices.
Region
Region: an area of Earth defined by one or more distinctive characteristics
Connection
Connection: refers to relationships among people and objects across the barrier of space.
VGI
VG1: (Volunteered geographic information) creation and dissemination of geographic data contributed voluntarily and for free by individuals.
Citizen Science
Citizen science: scientific research by amateur scientists.
PGIS
PGIS: (participatory GIS) community-based mapping.
Mashup
Mashup: a map that overlays data from one source on top of a map provided by a mapping service
Map scale
Map scale: level of detail and the amount of area covered on a map.
Projection
Projection: The scientific method of transferring Earth to a flat map.
Robinson
Robison: allocates space to oceans but shows land areas much smaller than on interrupted maps of the same size.
Homolosi
Homolosi: “the orange peel map,” is good at mapping human phenomena across space.
Mercator
Mercator: minimizes the distortion of shape and direction but grossly distorts the area toward the poles
Gall Peters
Gall-Peters: a projection that does not distort relative size, but does distort the shape.
Winkel
Winkel: The relative size of the landmasses on the map is the same as in reality.
Meridian
Meridian: an arc connecting the North and South poles.
Longittude
Longitude: location of each meridian is identified on Earth’s surface according to a numbering system.
Parallel
Parallel: a circle drawn around the globe parallel to the equator and at right angles to the meridians.
Lattitude
Latitude: numbering system to indicate the location of a parallel.
Isoline Map
Isoline Map: connects with lines all the places that have particular values
Dot distribution
Dot Distribution: depicts data as points and shows how those points are clustered together or spread out over an area.
Chloropleth
Choropleth: A map where recognizable areas are shaded or patterned in proportion to the measurement of the variable.
Graduated Symbol
Graduated Symbol: Displays symbols that change in size according to the value of the variable
Cartogram
Cartogram: A map in which the size of the country or U.S. state is proportional to the value of a particular variable.
Place
Place: a specific point on Earth distinguished by a particular characteristic.
Topynym
Toponym: name given to a place on Earth.
Site
Site: the physical character of a place.
Situtation/Relative Location
Situation/Relative location: location of a place relative to other places.
