Animated Maps

Definition - Just as an animated cartoon is a cartoon that moves, an animated map is a map that moves. Cartographic Animation is any moving presentation that shows spatial change by rapidly displaying a series of frames.

 

Why? - Cartographic Animation describes something that would not be evident if the map were viewed individually, such as trends and processes

Types:

  • Presentation - Allows the viewer little or no control over the progress of the product; the animation is only viewed.
  • Interative - Offer the viewer considerably more control over the course of the animation.

 

Animation Variables:

  • Size - the size of an area on a map may be changed to show changes in value
  • Shape - An area on a map can be made to change shape
  • Position - A dot moved across the map to show a change in location
  • Speed - The speed of movement varies to accentuate the rate of change
  • Viewpoint - A change in the angle of view, could be used to accentuate a particular part of the map as part of an animation
  • Distance - A change in the proximity of the view to the scene, as in the case of perspective view (Map scale)
  • Scene - The use of visual effects such as fade, mix, and wipe to indicate a transition in an animation from one subject to another
  • Texture, Pattern, Shading, Color - To change a variable being displayed

Spinning Corvallis

Volcanic Eruptions


Types of Animation:

  • Frame Based
    • Simplest Form
    • Series of individual full frames
    • Illusion of movement by changing frames quickly
    • Examples are flip books and slide shows
  • Cast Based
    • Based on cels (individual layer of a frame animation)
    • Uses tweening to create motion between keyframes
      • Position
      • Orientation
      • Color
      • Intensity
      • Camera focal length

Classification:

  • Temporal - Depicts sequences of change over time
  • Non-Temporal - Depicts change over space or attribute, not time
