MCQ (Single Correct) +4 −1

Examples of Raster data are

(A) DTM

(B) Spaghetti

(C) DEM

(D) Arcinode mode!

Choose the correct answer from the options given below:

(A), (C), and (D) only (A) and (D) only (A), (B), (C) and (D) (A) and (C) only Correct

Raster vs. Vector Data Models in GIS:
Raster Formats: Continuous regular grid arrays of cells/pixels. Digital Elevation Models (DEM, C) and Digital Terrain Models (DTM, A) are classic continuous raster grids.
Vector Formats: Feature models composed of coordinate points, lines, and polygons (e.g., Spaghetti models and Arc-node topological models).
Conclusion: DTM and DEM (A and C only) represent raster data. (Correct answer: Option 4)
