Which of the following statements regarding vector data is incorrect?

1. Vector data can represent lines and points.

2. Vector data always uses continuous data.

3. Vector data can represent polygons.

4. Vector data is used for detailed geographic features.

The correct answer is: Vector data always uses continuous data.

Vector data is characterized by its ability to represent geometric shapes such as points, lines, and polygons. Each of these shapes is defined by a precise set of coordinates, making vector data particularly effective for representing specific geographic features. The statement that vector data always uses continuous data is incorrect. In fact, vector data consists of discrete data, where individual points, lines, and polygons represent distinct entities or locations. This contrasts with continuous data, which would be better represented by raster formats, where each cell in a grid can take on a range of values and depict phenomena that vary continuously across space, such as temperature or elevation. The other options accurately describe vector data. It can indeed represent lines and points, such as roads (lines) and cities (points), and it can represent polygons that define areas like parks or lakes. Additionally, vector data is well suited for detailed geographic features, due to its precision and the ability to encode rich attribute information about those features.
