What is the purpose of recovery evidence in dependent resurveying?

1. To completely discard prior survey data

2. To collect data for creating new boundaries

3. To find evidence of original corners and lines for accurate restoration

4. To analyze modern mapping technology

The correct answer is: To find evidence of original corners and lines for accurate restoration

The purpose of recovery evidence in dependent resurveying is to find evidence of original corners and lines for accurate restoration. When conducting a dependent resurvey, surveyors aim to restore boundaries that have been established by previous surveys. This involves locating original survey markers, such as corner monuments or lines referenced in earlier works, to ensure that the current survey aligns correctly with historical data. By finding this recovery evidence, surveyors can verify and potentially restore the intended original survey lines or corners that may have been disturbed or lost over time. This process not only helps maintain the integrity of property boundaries but also supports the legal and historical context of land ownership and use. Hence, relying on recovery evidence is essential to achieve accurate and reliable results in dependent resurveying, making this the correct understanding of its purpose.
