5. SELECTION OF SURVEY STATIONS

  1. The following points should be remembered during the selection of survey stations:
  2. The stations should be so selected that the general principle of surveying may be strictly followed.
  3. The stations should be intervisible.
  4. The stations should be selected in such a way that well-conditioned triangles may be formed.
  5. The base line should be the longest of the main survey lines.
  6. The survey lines should be taken through fairly level ground, as far as practicable.
  7. The main survey lines should pass close to the boundary line of the area to be surveyed.
  8. The survey lines should be taken close to the objects so that they can be located by short offsets.
  9. The tie stations should be suitably selected to fix the directions of adjacent sides.
  10. The subsidiary stations should be suitably selected for taking check lines.
  11. Stations should be so selected that obstacles to chaining are avoided as far as possible.
  12. The survey lines should not be very close to main roads, as survey work may then be interrupted by traffic.

FAQs on Selection of Survey Stations - Chain Surveying, Surveying and Levelling - Surveying and Levelling Notes- Agricultural Engg - Agricultural Engineering

1. What is chain surveying and how is it used in the selection of survey stations?
Chain surveying is a method of surveying that involves measuring distances and angles using a chain or tape. In the selection of survey stations, chain surveying is used to establish control points and measure distances between them. These control points are then used as reference points for further surveying work.
2. What factors should be considered when selecting survey stations for chain surveying?
When selecting survey stations for chain surveying, several factors should be considered. These include the accessibility of the station, the visibility between stations, the stability of the ground, and the availability of suitable reference points. Additionally, factors such as the purpose of the survey and the accuracy required should also be taken into account.
3. How does surveying and leveling relate to the selection of survey stations in agricultural engineering?
Surveying and leveling play an important role in the selection of survey stations in agricultural engineering. These techniques are used to determine the elevation and slope of the land, which are crucial for various agricultural activities such as irrigation, drainage, and land grading. By accurately determining the topography of the area, surveying and leveling help in identifying suitable survey stations for different purposes in agricultural engineering.
4. What are the key steps involved in selecting survey stations for agricultural engineering projects?
The key steps involved in selecting survey stations for agricultural engineering projects are as follows: 1. Define the purpose of the survey: Determine the specific goals and objectives of the project, such as designing an irrigation system or optimizing land use. 2. Conduct a preliminary survey: Gather existing data and conduct a preliminary survey of the area to identify potential survey stations and understand the topography. 3. Evaluate accessibility and visibility: Assess the ease of accessing the survey stations and the visibility between them to ensure efficient surveying operations. 4. Consider ground stability: Evaluate the stability of the ground at potential survey stations to avoid any issues during construction or agricultural activities. 5. Determine reference points: Identify suitable reference points that can serve as benchmarks for future measurements and calculations.
5. How can the selection of survey stations impact the overall success of an agricultural engineering project?
The selection of survey stations has a significant impact on the overall success of an agricultural engineering project. The accuracy and reliability of the survey data collected from these stations determine the precision of subsequent design and construction activities. Properly selected survey stations ensure that accurate measurements are obtained, leading to efficient planning, optimal resource utilization, and the successful implementation of agricultural engineering projects.
