what is a geographic grid
A mesh of intersecting Latitudes and Longitudes drawn on a map
latitude (parallels)
horizontal, equally spaced; length decreases closer to the poled
longitude (meridians)
vertical, Equal in length, meet at the poles
what are the 6 basic elements of a map? (TLSCBC)

the difference between small-scale and large-scale
Determines the amount of detail
Small scale: only large features shown
Large scale: more details shown
what are the 3 types of map distortions? (CEE)
conformal, equal area, equidistant
conformal distortion
feature shape is preserved, area/size is distorted
equal area distortion
the area is correctly represented, the shape is distorted
equidistant distortion
preserves distance, other aspects distorted
area class map
divides Earth into zones based on categories of phenomenon
choropleth map
colors represent different quantities into different areas
isoline map
quantities that vary continuously over space
-represented with lines and colors
cartogram
shapes and areas have been purposely distorted
-largest area shown equals the largest population
the 3 types of geospatial technologies
remote sensing, global positioning system, global information systems
