Visual deck Flashcards
Describe the history of mapmaking with this chart
Starts out with woodcuts and block printing, then copperplate printing then lithography with a short period in the US with Wax printing around the 1800-1900 but it never caught on anywhere else.
Describe the process of measurement
- Clarify the Concept
- Operationalize the Definitions
- Identify the Variables
- Measure the outcomes
- Collect the data
Describe the Model for map communication
- Consider what the real-world distribution of the phenomenon might look like
- Determine the purpose of the map and its intended audience.
- Collect data appropriate for the maps purpose.
- Design and construct the map.
- Determine whether users find the map useful and informative.
abrupt and smooth, continuous discrete
Models of geographic - phenomena arranged along continuous/discrete and abrupt/smooth continua
MacEachran and DiBiase’s model of appropriate simbolization for discrete/continuous; abrupt smooth data
Proportional symbol, dot, cloropleth, isopleth/isarythmec map.
Key to effectiveness of visual variables for each level of measurement for areal phenomena
orientation, shape, arrangement, hue=nominal
lightness, hue=ordinal
persepective height=”numerical” (although hidden enumeration units and a lack of a north orientation are problems).
Color visual variables for quantitative phenomena (Hue, Lightness and saturation) Many more possiblities than Qualitatative (Just hue).
Snyder’s map projection guidline showing projections for mapping the world
Most significant are
The Conformal:
Mercator (constant scale along an Equator)
Transverse Mercator (Constant scale along a meridian)
Oblique Mercator (Constant scale along an oblique great circle)
Equivalent:
Molleweide (Non-interrupted)
Eckert IV+VI
McBryde/McBryde Thomas
Sinusoidal
Compromise distortion
Miller Cylindrical
Robinson pseudocylindrical
What projection is this?
Briesemiester modified azimuthal projection centerd at 10 degrees E and 45 degrees north. A projection used to map the world.
