Question

Conversion of raster image into vector data is known as:

• A. Rasterisation
• B. Resampling
• C. Topology creation
• D. Vectorisation

Hint:

Remember: \[ \boxed{ \begin{aligned} \text{Raster} \rightarrow \text{Vector} &:\ \text{Vectorisation} \text{Vector} \rightarrow \text{Raster} &:\ \text{Rasterisation} \end{aligned} } \]

Answer 1

The Correct Option is D

Concept: Vectorisation is the process of converting raster (pixel-based) images into vector features such as points, lines, and polygons.

Step 1: Understand vectorisation. It extracts geometric features from raster images for use in GIS analysis.

Step 2: Identify the correct term. Hence, \[ \boxed{\text{Raster} \rightarrow \text{Vector} = \text{Vectorisation}.} \] Therefore, the correct option is \[ \boxed{(D).} \]
