Question

Which one of the following is incorrect with reference to the Raster Data?

• A. Discrete Data
• B. Continuous data
• C. Made up of PIXELS
• D. Larger file size

Hint:

In GIS, raster data represents the world as a grid of cells or pixels, where each cell stores a value.

Answer 1

The Correct Option is A

Step 1: Picture raster data.
Raster data sees the world as a grid of small square cells called pixels, and every cell holds a value.

Step 2: Note it is made of pixels.
So the statement that raster data is made up of pixels is true.

Step 3: Note the file size.
Because every cell must store a value, even empty areas, the files become large. So large file size is also true.

Step 4: Think about what raster shows best.
Raster is ideal for smoothly varying things like elevation, temperature and rainfall, that is continuous data. So "continuous data" is a correct feature.

Step 5: Find the odd one out.
Sharp, separate, countable objects are discrete data, and these are better shown by vector data, not raster.

Step 6: Conclusion.
The statement that does not fit raster data is "discrete data".
\[ \boxed{\text{Discrete Data}} \]
