DiscreteField class final

Discrete integer values associated with each point across a two-dimensional (x, y) extent.

Discrete fields are sometimes called thematic, categorical, or discontinuous data. They most often represent objects with known and definable boundaries. A lake is a discrete object within the surrounding landscape. Where the water's edge meets the land can be definitively established. Other examples of discrete objects include buildings, roads, and parcels. Discrete objects are usually nouns.

Examples of discrete fields include:

  • Land classification
  • Boundaries
  • Parcels
  • Zoning
Implemented types
