Zorluk: KolayElementary Surveying Instruments and Fieldwork

During elementary fieldwork, a geography student needs to mark intermediate stations along a baseline to ensure a perfectly straight line over long distances. Which surveying instrument is designed for maintaining this straight alignment?

  1. Ranging poleCevap
  2. B
    Barometer
  3. C
    Hygrometer
  4. D
    Wind vane

Cevap

The ranging pole is the elementary surveying instrument used to mark stations and maintain straight alignment during fieldwork.
The correct answer is the ranging pole because its primary purpose in chain and compass surveying is to mark survey stations and facilitate the process of 'ranging'—aligning intermediate points along a straight survey line.

Adım Adım Çözüm

1
Identify the fieldwork task described in the stem.
The task requires marking intermediate points to align survey lines straight over a distance.
Maintaining a straight baseline is essential in chain surveying before linear distance measurements are recorded.
2
Match the required function with the appropriate instrument.
The ranging pole (or ranging rod) is designed specifically for sighting and alignment (ranging) along survey lines.
Ranging poles are painted with alternating colors (red/white or black/white) to make them clearly visible from a distance.
