(i) Surveying in the science of determining the relative positions on ground, along with their elevations.
(ii) The relative positions are determined by measuring horizontal distances, horizontal angles, vertical distances and vertical angles. For this, various instrument are needed.
(iii) The entire work stages of survey operation in civil engineering may be divided into the following three stages:
- Field work
- Office work
- Care and adjustment of instruments
Field work:
(i) The field work consists of the measurement of all the necessary horizontal and vertical distances, horizontal and vertical angles, elevations, etc., and keeping a systematic record of what has been done in a field book. Fieldwork is further subdivided into;
- Reconnaissance
- Field measurements
- Observations field record
Office Work:
(i) The office work of a surveyor consists of three types based on the field records.
- Drafting
- Computing
- Designing.
Care and adjustment of instruments:
A great care is required to handle the survey instruments in both field and office. A beginner should always be made familiar with care and adjustment of the instruments and their limitations. Precise instruments like theodolite, level, prismatic compass, etc. need more care than the equipment such as chains, arrows, ranging rods, etc.
So, the correct sequence of surveying operation is:
Reconnaissance → Field observations → Data analysis → Map making

In general, CORRECT sequence of surveying operations isa)Reconnaissan...
Answer:
Introduction:
Surveying is the process of determining the relative positions of points on or near the Earth's surface. It involves a series of operations that are performed in a specific sequence to ensure accurate and reliable results. The correct sequence of surveying operations is as follows:
1. Reconnaissance:
Reconnaissance is the initial step in the surveying process. It involves gathering preliminary information about the survey area, such as the purpose of the survey, the location of the survey area, and any existing maps or data that may be available. During this stage, the surveyor also evaluates the terrain and identifies any potential challenges or obstacles that may affect the surveying process.
2. Field observations:
Once the reconnaissance is complete, the surveyor proceeds with the field observations. This step involves collecting data on the ground using various surveying instruments and techniques. The surveyor measures distances, angles, and elevations of specific points and features in the survey area. This data is crucial for creating an accurate map of the area.
3. Data analysis:
After the field observations are complete, the surveyor analyzes the collected data. This step involves processing and interpreting the measurements to determine the relative positions of the surveyed points. The surveyor may use mathematical calculations and computer software to perform this analysis. Data analysis helps identify any errors or discrepancies in the measurements and ensures the accuracy of the final results.
4. Map making:
The final step in the surveying process is map making. Based on the analyzed data, the surveyor creates a map that represents the surveyed area accurately. The map includes the locations of surveyed points, as well as any relevant features, such as roads, buildings, and natural landmarks. The map serves as a visual representation of the survey results and is used for various purposes, such as planning, design, and construction.
Conclusion:
The correct sequence of surveying operations is reconnaissance, field observations, data analysis, and map making. This sequence ensures that the surveying process is carried out systematically and produces accurate and reliable results. Each step in the sequence builds upon the previous one, leading to a comprehensive understanding of the survey area and the creation of an accurate map.
