Question

Which one of the following is disadvantage of Raster data format?

Options

• Simple data structure

• Easy and efficient overlaying

• Compatible with remote sensing imagery

• Difficult network analysis

Answer 1

Difficult network analysis

Explanation:

Raster data represents geography using a grid of square pixels, which makes it impossible to define precise mathematical connections between linear features. Because pixel grids cannot accurately track specific paths and intersections, conducting network analysis, such as finding the shortest road routes or tracing pipelines, is extremely difficult and inaccurate compared to vector data.
