In surveying, the main principle is to start from the whole and move towards the part. This ensures accuracy and efficiency in measuring and mapping, especially when conducting land surveys.
Step 1: Understanding the principle.
The principle of working from the whole to part means that surveyors first establish the large-scale features or reference points, which then guide the measurement of smaller, more detailed features. This method helps in minimizing errors as the survey progresses.
Step 2: Analyzing the options.
- Option (A) is correct because it correctly states that surveying starts from the whole (large-scale) and moves towards the part (smaller details).
- Option (B) is incorrect because working from part to whole would be inefficient and prone to errors as small-scale measurements would be based on incomplete data.
- Option (C) and Option (D) are incorrect because the elevation order (higher to lower or vice versa) is not related to the main surveying principle; it focuses on the logical measurement progression.
Thus, the correct answer is (A).
