The value of an Attribute is the specific value of that feature, e.g. A hydrant object has an Attribute Value of “height” of 1.2 m.
Attribute Structure is the formal record of a set of Attributes describing a Vector Layer and the Objects within it.
- The single Attribute of the Hydrants Layer is Height.
- An example of Hydrants Layer Attribute Structure: [ID, Height, Colour, Type, State].
- Values for a single Object, e.g. [ID:7, Height: 1.2, Colour: Red, Type: Ground, Condition: Good] are Attribute Values.
