Question

Which one of the following statements is NOT correct in the context of Geographic Information System?

• A. A raster data model makes use of grid of cells that are organized into rows and columns for representation of features on Earth
• B. Vector data model represents the spatial features on Earth’s surface in terms of points, lines or polygons
• C. Resampling is applied after georeferencing of vector datasets
• D. Topology is used in vector data models to ensure spatial data integrity

Hint:

Remember: {Resampling} is only applicable to {raster datasets} during or after georeferencing. Vector datasets involve coordinate transformation, not resampling.

Answer 1

The Correct Option is C

Resampling is a process applied during or after georeferencing, but it is specific to raster datasets. It involves interpolation methods to estimate pixel values when transforming the raster image to align with a coordinate system.

On the other hand, vector data, which consists of discrete geometric features like points, lines, and polygons, does not undergo resampling. Instead, vector georeferencing involves transformation of coordinates directly, without changing the nature of data through interpolation.

Therefore, option (C) is not correct, making it the right choice for this question.
