Generalization Flashcards
Generalization
Process of reducing detail and grouping phenomena together
Congestion
Too many objects are compressed into too small of a place
Coalescense
Objects overlap due to scale change features graphically collide due to scale
change
Major Vector Based Operations
Simplification, Smoothing, Aggregation, Displacement, Enhancement, Amaligation, Collapse, Merging, Exaggeration
Simplification
eliminating the maximum number
of coordinates while retaining as much of the
geometry of the feature as possible.
Smoothing
shifting the position of points to
improve the appearance of the feature (reduces angularity)
Aggregation
joining multiple point features together
Amalgamation
the process of fusing together nearby polygon for both noncontinuous and continuous areal data.
Collapse
Involving conversion of geometry
Merging
the operation of fusing together groups of line features
Exaggeration
amplifying a specific part of an object to maintain clarity in scale reduction
Displacement:
requiring complex measurement to relocate the features
Enhancement
a symbolization change to emphasize the importance of a particular object
Equal Interval
Each class occupies an equal interval along the number line
Quantile
Data are rank-ordered and equal numbers of features (observations) are placed in each class.
