CV-21 - Map reading
- Discuss the advantages and disadvantages of using conventional symbols (e.g., blue=water, green=vegetation, Swiss cross=a hospital) on a map
- Find specified features on a topographic map (e.g., gravel pit, mine entrance, well, land grant)
- Match map labels to the corresponding features
- Match the symbols on a map to the corresponding explanations in the legend
- Execute a well designed legend that facilitates map reading
- Explain how the anatomy of the eye and its visual sensor cells affect how one sees maps in terms of attention, acuity, focus, and color
- Explain how memory limitations effect map reading tasks
CV-06 - Map Projections
Map projection is the process of transforming angular (spherical / elliptical) coordinates into planar coordinates. All map projections introduce distortion (e.g., to areas, angles, distances) in the resulting planar coordinates. Understanding what, where, and how much distortion is introduced is an important consideration for spatial computations and visual interpretation of spatial patterns, as well as for general aesthetics of any map.
