Question

In a Vector data model, which of the following is representation of an area?

• A. Points
• B. Pixels
• C. Polygon
• D. Nodes

Hint:

Remember: \[ \boxed{ \text{Point} \rightarrow 0D \qquad \text{Line} \rightarrow 1D \qquad \text{Polygon} \rightarrow 2D } \]

Answer 1

The Correct Option is C

Concept: In the vector data model, geographical features are represented using points, lines, and polygons. Area features are represented using polygons.

Step 1: Recall vector feature types. \[ \boxed{ \begin{aligned} \text{Point} &\rightarrow \text{Well, Pole, Tree}\\ \text{Line} &\rightarrow \text{Road, River}\\ \text{Polygon} &\rightarrow \text{Lake, Forest, Land Parcel} \end{aligned} } \]

Step 2: Identify the representation of area. Since polygons enclose a closed boundary, \[ \boxed{\text{Area features are represented by polygons}.} \] Therefore, the correct option is \[ \boxed{(C).} \]
