geographic field

A geographic field is a way of describing how a particular property or measurement varies across a physical space, like a map. For example, temperature, elevation, or pollution levels can be represented as fields, where each point in an area has a specific value. These fields help scientists and planners understand patterns and relationships in the environment, societal data, or natural phenomena across different locations. Think of it as a continuous "layer" of information spread out over a geographic area, showing how something changes from place to place.
