Question

What is attribute uncertainty?

• A. Error due to imprecision in coordinate registration
• B. Error due to incorrect labelling or quantification of features
• C. Error in the source document due to cartographic bias
• D. Error associated with displacement of the object from its true location

Hint:

Attribute uncertainty deals with errors in the description or classification of features, whereas spatial uncertainty involves errors in the positioning or location of features.

Answer 1

The Correct Option is B

Attribute uncertainty refers to the error that arises from the incorrect labelling or quantification of features in a GIS database. This can occur when attributes like names, quantities, or classifications are recorded incorrectly due to misinterpretation or human error.
Step 1: Understanding Attribute Uncertainty
- Option A refers to coordinate registration, which is a form of spatial uncertainty, not attribute uncertainty.
- Option B correctly identifies attribute uncertainty as errors related to mislabelling or misquantifying features.
- Option C refers to cartographic bias, which affects map accuracy but is not directly related to attribute uncertainty.
- Option D refers to displacement errors in spatial location, which is a form of positional uncertainty, not attribute uncertainty. Step 2: Conclusion
Thus, the correct answer is (B) Error due to incorrect labelling or quantification of features.
