Organizing Principle: Level Of Detail
A Level Of Detail Related aggregate organizes different representations of the same underlying data that differ in level of detail. It may capture any of several different varieties of the general "level of detail" concept, including:
- Distance - Each branch represents data as seen by an observer at some specified distance range from a given point.
- Volume - Each branch represents data as seen by an observer inside (or outside) a volume specified for that branch.
- Spatial Resolution - Each branch specifies data at a different resolution.
- Map Scale - Each branch specifies data at a different map scale.
