Surveying is the process of measuring, mapping and understanding the earth’s surface. It is a civil engineering discipline that has been around for centuries.
Surveying is a very important field of study because it helps us understand how the earth works. It helps us map out the land so we can better understand how to use it to our advantage. Surveying also helps engineers and architects design buildings and other structures that will stand up to earthquakes or floods, which are two things that are getting very common due to the changing climate.
Surveying can be done with a variety of instruments such as: GPS, total stations, transit levels, lasers and magnetic compasses. These instruments can be carried in hand, and are mostly mounted on vehicles ranging from trucks, drones, boats and even artificial satellites that are orbiting the earth in space.
Cadastral and Hydrographic Surveying
Cadastral surveying is a form of land surveying that is used to determine the ownership and boundaries of land parcels. Cadastral surveys are conducted for a variety of purposes including property rights determination, engineering projects such as new construction or mining operations, environmental studies such as wetland delineation or wildlife habitat mapping.
Hydrographic surveying is a hydrodynamic survey method that measures the depth and shape of water bodies. This survey method is used by engineers to measure the depths and shapes of rivers, lakes, harbors, and other bodies of water.
Hydrographic surveys are performed using a variety of tools including echo sounders, sonar, or radar waves to determine the depth and shape of a body or channel’s bottom. These measurements are then compiled into detailed charts for navigation purposes.
Both cadastral and hydrographic surveying are used for different purposes. Cadastral surveys are done to determine ownership and boundaries for land parcels while hydrographic surveys are done to measure features on water surfaces and underneath the water surface, like measuring the sand deposits under the riverbed.
The History and Origins of Cadastral Surveying
Surveying is the process of measuring land and property to determine their boundaries and identities. Cadastral surveying, also known as land surveying, is a type of surveying that determines the boundaries and ownership of land.
The history of cadastral surveying goes back to ancient times when people used sticks to measure distances on the ground. It wasn’t until the 18th century when tools like chains, tapes, and levels were used to measure distances in more detail.
The History and Origins of Hydrographic Surveying
Hydrographic surveying is a technique for measuring water depths and the shape of the bottom of a body of water. The origins of hydrographic surveying date back to ancient times. The earliest evidence is from the time of Alexander the Great, when his army created maps that were used for navigation.
It has been used in nautical navigation since ancient times and its use has increased as technologies have evolved. It was developed to its current state in 1837 by Sir John Ross, who was an early pioneer in this area.
The Differences Between Hydrographic Surveying and Cadastral Surveying
Hydrographic surveying deals with the measurement and mapping of the earth’s surface or water surfaces, primarily for navigational purposes. Cadastral surveying is a form of land surveying that deals with establishing and describing boundaries. The two types of surveys are different in their methods and goals.
Hydrographic surveys are done by measuring the depth of water and determining what is on the bottom of it, such as sand, gravel, rocks, etc. Cadastral surveys are done by measuring property lines to determine how much property a person owns.
The Similarities Between Hydrographic Surveying and Cadastral Surveying
Hydrographic surveying is a type of surveying that is used to map the underwater contours of a body of water. Cadastral surveying, on the other hand, is the process by which boundaries are determined and recorded.
Both hydrographic and cadastral surveys are necessary in order to provide accurate maps for navigation or for establishing land ownership.
What You Should Know about Cadastral Surveys in Australia
The cadastral survey process will vary depending on whether you are looking to purchase or sell property in Australia. If you’re purchasing property, then your solicitor will usually carry out the cadastral survey work on your behalf. On the other hand, if you’re selling property, then it will be your responsibility to organise this work.
