Types of Geographic Map Features



General Feature Types:

Two ways to represent geographic features:

- multi-attributes associated with features
- much of analysis performed by attribute tables

- best used for continuous phenomenon such as vegetation, precipitation
- much of analysis performed by combining new layers


Functional Feature and Surface Types:

- use series of sample points to "interpolate" areas between (isolines)
- spectrum or enclosed areas (polygons)
