A reflectorless total station is particularly useful for which scenario?

1. Measuring distances only

2. Inaccessible points

3. Only angles are needed

4. Rapid angle and distance collection

The correct answer is: Inaccessible points

A reflectorless total station is designed to measure distances to a target without the need for a physical reflector. This capability is particularly advantageous in scenarios where access to the point being measured is limited or blocked, such as when measuring across a street, over water, or in densely populated areas where placing a reflector may be impractical or impossible. The device employs advanced technology, such as laser ranging, allowing surveyors to take measurements without direct physical contact with the target. This makes it ideal for situations where the points of interest are difficult to reach or would require extensive setup to achieve a conventional measurement. In contrast, measuring distances only or focusing solely on angles does not leverage the unique capabilities of a reflectorless total station. Rapid angle and distance collection may also not directly address the concern of accessibility, whereas the ability to measure inaccessible points is the primary strength of reflectorless technology.
