Question

When is a transformation required while projecting data?

A. when the input data source is a network
B. when the input and output geographic coordinate systems are different
C. when the input and output spatial references are different
D. when the input feature class has an unknown spatial reference

Answer 1

A transformation is required when the input and output spatial references are different.

Step-by-step explanation:

The correct answer to this question is C. When the input and output spatial references are different. When projecting data, a transformation is required when the input and output spatial references are different. This is because different spatial references have different coordinate systems and units of measurement, and a transformation is necessary to accurately align and represent the data in the new spatial reference.
