Question:
Which of the following statement is not true for spaghetti data structure?
Which of the following statement is not true for spaghetti data structure?
Show Hint
"Spaghetti" refers to tangled vector lines with no defined relationships. "Grids" belong exclusively to the Raster world (like pixels in a digital photo).

- It is the most simple data structure.
- It is efficient for CADD database.
- All entitities are spatially defined, without any spatial relationships.
- It divides the entire area into regular grids.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Spatial data in GIS is broadly categorized into two primary structures: Vector and Raster models. The spaghetti model is a specific type of vector data structure.
Step 2: Meaning
We need to identify the characteristic that belongs to a different data model, making it false for the spaghetti structure.
Step 3: Analysis
• The spaghetti model is a vector structure where lines are recorded as independent strings of X, Y coordinates without topology (meaning no spatial relationships are stored). This confirms statements A, B, and C are true.
• Dividing the entire area into regular, uniform grids (cells/pixels) is the fundamental definition of the raster data model, not the vector/spaghetti model.
Step 4: Conclusion
Therefore, the statement describing grid division applies to raster data and is false for the spaghetti data structure. Final Answer: (D)
