Question

The third dimension used in GIS represents:

• A. \(\text{Latitude} \)
• B. \(\text{Altitude} \)
• C. \(\text{Magnitude} \)
• D. \(\text{Longitude} \)

Hint:

In 3D GIS, the third dimension (Z-axis) represents altitude or elevation, essential for terrain modeling and analysis.

Answer 1

The Correct Option is B

Step 1: Understanding GIS dimensions. - GIS data is typically represented in three dimensions (3D): - Latitude (X-axis): Represents the horizontal position. - Longitude (Y-axis): Represents the vertical position. - Altitude (Z-axis): Represents height or elevation above a reference surface.
Step 2: Explanation of incorrect options. - Latitude a.: A horizontal coordinate, not a height measurement. - Longitude d.: A vertical coordinate, not representing height. - Magnitude c.: Refers to size or extent, not a spatial coordinate.
Step 3: Selecting the correct option. Since the third dimension (Z-axis) in GIS represents altitude (height/elevation), the correct answer is b. Altitude.
