Chain surveying

 Chain Surveying is a type of traditional surveying that involves measuring linear distances using a chain or tape and recording the location of objects and features on the earth’s surface. The process involves a surveyor walking along the ground with a chain or tape and using other instruments, such as a compass or a level,…

Instruments Used in Surveying

 Surveying instruments are tools used by surveyors to measure and accurately determine the size, position, and shape of objects and features on the earth’s surface. Some common surveying instruments include: Total Station: An electronic instrument that combines an electronic theodolite and an electronic distance meter to measure angles and distances on the earth’s surface. Theodolite:…

Astronomical Survey

 Astronomical Surveying is a type of surveying that uses astronomical observations to measure the positions and movements of celestial objects, including stars, planets, and satellites. The purpose of Astronomical Surveying is to provide accurate and up-to-date information about the positions and movements of celestial objects, which is critical for a wide range of applications, including…

Marine (or) Hydrographic Survey

 Marine Surveying, also known as Hydrographic Surveying, is a type of surveying that focuses on mapping and documenting the features of bodies of water, including oceans, lakes, rivers, and harbors. The purpose of Marine Surveying is to provide accurate and up-to-date information about the bathymetry, topography, and hydrodynamics of waterways, which is critical for a…

City surveying

 City Surveying, also known as Urban Surveying, is a type of land surveying that focuses on mapping and documenting the physical and cultural features of urban areas, including buildings, infrastructure, parks, and public spaces. The purpose of City Surveying is to provide a comprehensive and accurate representation of the built environment, which is critical for…

Cadastral survey

 A Cadastral Survey is a type of land surveying that focuses on determining and mapping the ownership and boundaries of land and property. The purpose of a Cadastral Survey is to provide accurate and up-to-date information about the ownership, size, and location of land and property, which is critical for a wide range of applications,…

Topographical survey

 A Topographical Survey is a type of land surveying that maps and describes the physical features of a piece of land, including its elevations, contours, and natural and man-made features. The purpose of a Topographical Survey is to provide a detailed and accurate representation of the land surface, including its shape, size, and features, for…

Land Surveying

 Land Surveying is the measurement and mapping of land and property boundaries, topography, and features. It involves the use of specialized equipment and techniques to accurately determine the location and dimensions of property lines, buildings, natural features, and other elements on the land surface. The main objective of Land Surveying is to provide accurate information…

Classification of Surveying

 Surveying can be classified into the following categories based on the type of measurement and application: Geodetic Surveying: deals with large-scale, precise measurements of the Earth’s surface, including its shape, size, and gravity field. Plane Surveying: deals with smaller-scale, two-dimensional measurements of land, including the location of boundaries, topography, and features. Engineering Surveying: provides critical…

Geodetic Surveying

Geodetic Surveying is a division of surveying that deals with the large-scale, precise measurement of the Earth’s surface, including its shape, size, and gravity field. It involves the determination of the exact position and orientation of points on the Earth’s surface using complex mathematical and geodetic techniques. In Geodetic Surveying, a variety of tools and…
