Question

Arrange the GIS Data Modelling Steps (A, B, C and D) in the correct order A. Identify possible features from the real world B. Use the selected method to represent the feature in the GIS C. Select a method for representing the feature D. Identify appropriate attributes for the feature

• A. A, B, D, C
• B. B, C, D, A
• C. B, A, C, D
• D. A, C, B, D

Hint:

GIS data modelling means deciding how real-world features will be represented inside the GIS.

Answer 1

The Correct Option is D

Step 1: List the four steps.
A. Identify features from the real world, B. Use the chosen method to represent the feature, C. Select a method to represent the feature, D. Identify the attributes.

Step 2: Decide what comes first.
You must first see what actually exists on the ground, so step A comes first.

Step 3: Decide the next step.
After spotting a feature you choose how to draw it, point, line or polygon. That is step C.

Step 4: Apply the chosen method.
Once the method is picked you actually use it to put the feature into the GIS. That is step B.

Step 5: Add the details.
Finally you attach the attributes that describe the feature, which is step D.

Step 6: Conclusion.
The correct order is A, C, B, D.
\[ \boxed{A,\ C,\ B,\ D} \]
