Test 2 Flashcards
Tweening
process of interpolating movement
between key frames
Stop frame animation
process by which individual frames are designed one by one
duration
how long a particular map frame in an animation is shown until the next is presented
rate of change
how quickly an image is morphed or switches to the displayed attribute
order
how data is displayed, doesn’t have to be temporaly but could be by value
Frequency
the amount or regularity of an attribute occurring within the object being animated
synchronization
two or more datasets displayed to show temporal correlations
“everything is related to everything else, but near things are more related to each other”
1st law of geography
Tobler
Cartograms
maps drawn so that all the areas of the internal enumeration unit are proportional to the attribute data they represent
Three types of cartograms
continuous, non-continuous and dorling/circular
proportional symbol map
represents the distribution of an attribute with a specific symbol
proportional map equation
area1/area2= value1/value2
three types of scaling symbols
absolute
magnitude
range
graduated symbols
data is grouped ordinaly
rules for proportion vs graduated
proportion NEVER has ranged scaling
graduated MUST have range scaling
Flow map
depicts movement/diffusion of phenomena
Three types of flow maps
radial; one source to multiple destinations
network; interconnectivity
distributive; multiple sources to selected locations
