Multiscale representation

Multiple representation concerns the various ways that features or phenomena are acquired and stored in databases and displayed on maps or other visual displays.

Depending on the display type, features or phenomenon may be represented in different ways. This is called multiscale representation. 

Simplifying features for map view is referred to as generalization.

Generalization

To display content legibly within the small space of a topographic map at a specific map scale, symbols must often be generalized. This means that the amount of information and detail shown must be reduced. This is particularly important for smaller-scale maps, which cover larger areas. Generalization involves a variety of techniques for selecting the appropriate content for a given scale and...

Feature representation

Feature representation is the way features or phenomenon on the earth’s surface are captured and stored in a database. Features, such as roads, streams, or soil types can be stored in raster or vector data formats. Raster data are stored like images that have rows, columns, and pixel values. Vector data are stored through point, line, and polygon representations.
