Surveying and levelling basics




Before we dive into the details of the book, let us first understand some basic terms and concepts related to surveying and levelling.


Definition and types of surveying




Surveying is the science and art of measuring and representing the relative positions and distances of natural or artificial features on or near the surface of the earth. It involves collecting data using various instruments such as tapes, levels, compasses, theodolites, total stations, GPS receivers, etc., and processing them using mathematical methods to produce maps, plans, drawings, charts, etc.


There are many types of surveying depending on the purpose, scale, accuracy, method, or instrument used. Some common types are:


  • Topographic survey: It is a type of survey that shows the shape and elevation of the land surface using contour lines or spot heights.



  • Cadastral survey: It is a type of survey that determines and records the boundaries and ownership of land parcels.



  • Engineering survey: It is a type of survey that provides data for the design, construction, and maintenance of engineering structures such as buildings, roads, bridges, dams, etc.



  • Hydrographic survey: It is a type of survey that measures and maps the features and depths of water bodies such as oceans, lakes, rivers, etc.



  • Aerial survey: It is a type of survey that uses aerial photography or remote sensing to capture images of the earth's surface from an airplane, helicopter, drone, satellite, etc.



Definition and types of levelling




Levelling is a branch of surveying that deals with the measurement and determination of the vertical distances or heights of points or objects above or below a reference level or datum. It is used to find the elevation of points, to establish benchmarks, to calculate cut and fill volumes, to set out grades, etc.


There are two main types of levelling:


  • Differential levelling: It is a type of levelling that determines the difference in elevation between two or more points by measuring the vertical distances between them using a level and a staff.



  • Trigonometric levelling: It is a type of levelling that determines the elevation of a point by measuring the horizontal distance and the vertical angle from a known point using a theodolite or a total station.



Instruments and methods used for surveying and levelling




There are various instruments and methods used for surveying and levelling depending on the type, accuracy, and complexity of the work. Some common instruments are:


  • Tape: It is a flexible measuring device made of cloth, metal, or plastic that is used to measure linear distances along straight or curved lines.



  • Level: It is an optical instrument that consists of a telescope mounted on a tripod that can be levelled using bubble tubes or electronic sensors. It is used to measure vertical angles or differences in elevation between points.



  • Compass: It is a magnetic instrument that consists of a needle that points to the magnetic north. It is used to measure horizontal angles or directions between lines.



  • Theodolite: It is an optical instrument that consists of a telescope mounted on a tripod that can be rotated in horizontal and vertical planes. It is used to measure horizontal and vertical angles between lines.



  • Total station: It is an electronic instrument that combines the functions of a level, a theodolite, and a distance meter. It is used to measure horizontal and vertical angles and distances between points using infrared or laser beams.



  • GPS receiver: It is an electronic device that uses signals from satellites to determine the coordinates and elevation of points on the earth's surface.



Some common methods are:


  • Chain surveying: It is a method of surveying that uses tapes or chains to measure distances along straight lines and offsets to locate features on the ground.



  • Plane table surveying: It is a method of surveying that uses a plane table, which is a drawing board mounted on a tripod with a sighting device called an alidade. It is used to plot the positions and directions of features on a sheet of paper by direct observation.



  • Tacheometric surveying: It is a method of surveying that uses a tacheometer, which is a special type of theodolite that has a stadia diaphragm in its telescope. It is used to measure horizontal distances and elevations by observing stadia hairs on a staff.



  • Triangulation surveying: It is a method of surveying that uses triangles as the basic units of measurement. It involves measuring the angles and sides of triangles formed by stations on the ground using theodolites or total stations.



  • Astronomical surveying: It is a method of surveying that uses observations of celestial bodies such as stars, sun, moon, etc., to determine the latitude, longitude, azimuth, time, etc., of points on the earth's surface using astronomical instruments such as sextants or chronometers.



Surveying and levelling applications




Surveying and levelling have many applications in various fields such as civil engineering, land surveying, geodetic surveying, etc. Here are some examples:


Surveying and levelling applications




Surveying and levelling have many applications in various fields such as civil engineering, land surveying, geodetic surveying, etc. Here are some examples:


Civil engineering projects




Surveying and levelling are essential for the planning, design, construction, and maintenance of civil engineering structures such as buildings, roads, bridges, dams, tunnels, etc. They are used to:


  • Determine the location, shape, size, and elevation of the land and the features on it.



  • Prepare maps, plans, drawings, and models of the proposed structures and their surroundings.



  • Establish horizontal and vertical control points and benchmarks for reference and accuracy.



  • Set out the alignment, grade, and dimensions of the structures according to the design specifications.



  • Monitor the progress and quality of the construction work and detect any deviations or defects.



  • Measure the quantities of materials used and the volume of earthwork done.



  • Conduct tests and inspections to ensure the safety and stability of the structures.



Land surveying




Land surveying is the process of measuring and mapping the boundaries and ownership of land parcels. It is also known as cadastral surveying or property surveying. It is used to:


  • Determine the legal rights and obligations of landowners and tenants.



  • Establish the location, shape, area, and value of land parcels.



  • Record and update the land records and deeds.



  • Resolve any disputes or conflicts over land boundaries or ownership.



  • Support land administration and management activities such as taxation, zoning, planning, development, etc.



Geodetic surveying




Geodetic surveying is the process of measuring and mapping the shape and size of the earth or a large part of it. It is also known as geodesy or geomatics. It is used to:


  • Determine the coordinates and elevations of points on the earth's surface using a global or regional reference system such as WGS84 or NAD83.



  • Study the physical phenomena that affect the earth's shape and gravity field such as tides, earthquakes, volcanoes, plate tectonics, etc.



  • Provide a common framework for integrating spatial data from different sources such as maps, satellite images, aerial photos, GPS data, etc.



  • Support various applications that require accurate positioning and navigation such as aviation, marine transportation, military operations, geospatial information systems (GIS), etc.



Surveying and levelling challenges




Sources of errors and uncertainties in surveying and levelling




There are many sources of errors and uncertainties that can affect the accuracy and reliability of the measurements and results in surveying and levelling. These errors can be classified into three types:


  • Systematic errors: These are errors that follow a consistent pattern or direction and can be predicted, corrected, or eliminated by applying proper adjustments or calibrations. They are usually caused by imperfect instruments, methods, or conditions. For example, instrumental errors such as collimation error, curvature and refraction error, etc., are systematic errors that can be corrected by applying suitable formulas or constants.



  • Random errors: These are errors that vary randomly in magnitude and direction and cannot be predicted or eliminated. They are usually caused by human mistakes, natural fluctuations, or environmental disturbances. For example, reading errors due to parallax, misalignment, or poor visibility, are random errors that can be reduced by taking repeated measurements or applying statistical methods.



  • Mistakes or blunders: These are errors that result from gross negligence, ignorance, or carelessness of the surveyor or the assistant. They are usually caused by wrong calculations, incorrect data entry, misreading of instruments or staffs, etc. For example, mistaking a foot for a meter, transposing digits, omitting a reading, etc., are mistakes or blunders that can be avoided by checking and verifying the work.



Techniques for reducing and adjusting errors in surveying and levelling




There are various techniques for reducing and adjusting errors in surveying and levelling to improve the quality and consistency of the measurements and results. Some common techniques are:


  • Calibration: This is the process of checking and adjusting the instruments to ensure that they are in good working condition and conform to the standard specifications. It involves comparing the instrument readings with known values or standards and applying corrections if necessary.



  • Compensation: This is the process of applying suitable formulas or constants to correct for the systematic errors due to imperfect instruments, methods, or conditions. It involves using mathematical models or empirical relationships to account for the effects of factors such as collimation error, curvature and refraction error, temperature variation, etc.



  • Averaging: This is the process of taking repeated measurements of the same quantity and calculating their arithmetic mean to reduce the random errors due to human mistakes, natural fluctuations, or environmental disturbances. It involves using statistical methods such as mean, median, mode, standard deviation, etc., to analyze the data and estimate the most probable value.



  • Closing: This is the process of verifying the accuracy of a surveying or levelling loop by comparing the initial and final readings of a closed traverse or circuit. It involves calculating the misclosure or discrepancy between the two readings and comparing it with the maximum allowable misclosure based on the required accuracy level.



  • Adjustment: This is the process of distributing the misclosure or discrepancy among the measurements of a surveying or levelling loop to minimize the errors and obtain consistent results. It involves using mathematical methods such as least squares adjustment, Bowditch's rule, Transit rule, etc., to allocate the corrections proportionally to each measurement.



Standards and codes of practice for surveying and levelling




There are various standards and codes of practice that govern the methods and procedures of surveying and levelling to ensure quality and consistency in the measurements and results. These standards and codes provide guidelines for selecting appropriate instruments, methods, techniques, accuracy levels, formats, etc., for different types of surveying and levelling works. Some examples of these standards and codes are:


  • The Standard for Australian Survey Control Network (SP1): This is a standard published by the Intergovernmental Committee on Surveying and Mapping (ICSM) that defines the specifications for establishing and maintaining a national network of survey control marks in Australia. It covers aspects such as classification, accuracy requirements, documentation requirements, etc., for different orders of survey control marks.



  • The Guideline for Control Surveys by Differential Levelling (SP1): This is a guideline published by the ICSM that provides recommendations for conducting differential levelling surveys using a level and level staff or a total station and fixed height prism in Australia. It covers aspects such as equipment, procedures, uncertainty evaluation, etc., for different orders of differential levelling surveys.



  • The International Standards of Surveying and Mapping (ISO 19100): This is a series of standards published by the International Organization for Standardization (ISO) that defines the principles and requirements for surveying and mapping activities in the context of geographic information systems (GIS). It covers aspects such as terminology, reference systems, data quality, metadata, etc., for different types of surveying and mapping data.
