Adkan - Land Surveying History

adkan land surveying history

Land surveys date back as far the early Egyptians, making it one of the world's most ancient professions. Since then, it has become a fundamental part of every major civilization, as nations needed to understand the shape of the land as well as demarcations in order to know what property was theirs.

The History of Land Surveying Techniques

Over the years, the principles of land surveying have remained the same, using the basic fundamentals of geometry, trigonometry and calculus, however, land surveying equipment has evolved into more advanced technology, which produces more reliable and accurate results. In earlier years, land surveys applied the right principles, however, due to a lack of more precise equipment, they were also less reliable.

Land Survey Types

There are a variety of land surveys, each designed to address its own application. Land surveys are categorized in three basic ways:

  •     Informational surveys-which are used to create charts and maps.
  •     Engineering surveys-which ensure the structure is constructed in the correct location.
  •     Standard land surveys-which calculate land areas and fix property lines etc.

Other sub categories that may factor into the land survey include: property surveys, route surveys, hydrographic surveys and industrial surveys.

Land surveys can also be plane surveys or geodetic surveys. Plane surveys deem the earth as a flat plane and are generally used to examine small areas, whereas, geodetic surveys cover much larger areas and require the curvature of earth to be taken into consideration. They also rely on further land survey techniques such as astronomical direction fixing, trilateration and triangulation for more precise readings.

Land Survey Techniques

There are five survey techniques commonly used today which include: leveling, radiation, trilateration, triangulation and traverse.

  •     Leveling-uses a leveling instrument to measure the difference in elevation in a specific area.
  •     Radiation-is used in combination with a plane table to measure a fixed position above ground.
  •     Trilateration-utilizes electronic measuring equipment to calculate the sides and lengths of triangles used in the triangulation, so that angles can be computed, and is commonly used to measure rough terrain.
  •     Triangulation-uses a series of conjoined triangles that overlap each other to measure angles from determined locations.
  •     Traverse-is commonly used for building roads. This technique utilizes a series of lines whose lengths and distances have been computed and are joined together by points in specific locations.

Land Surveying is More than Science

Survey Science

Land surveying is a very practical science that tells everyone how their properties are put together. It is something that people need when they are developing land, and it is something that is needed when even the smallest change is going to be made to a property. There is a lot that has to be done to show that the land is going to be the right size for the plot. or the surveyor is going to show the exact size of the plot using their instruments for the first time.

These people are scientists who are using their instruments to show that land they are on has specific measurements. Everything is based on small points that need to be verified by the community, and the surveyor can set up so much after that that it is hard to believe they got all that information from just one point. They use special instruments that explain the distance they are looking at, and they are using their calculations to figure out how far something goes on any side. They detail the area, and then they mark each area.

They know how to calculate the size and area or anything, and they can calculate the borders of any property as they are working. Their work is very important because it has to be done if there is going to be any levying or taxation in a community. It needs to be done if there is zoning in the area, and it needs to be done if people are going to confirm what the size of the lot is going to be. That is needed when there are property line disputes, and it can be used when people are wondering how they are going to block out a piece of land they purchased. The surveyor is going to spend hours on this every day making sure that their people are going to get measurements all around the area, and they are going to keep at it until there is a report on the whole area.

There are many reasons to do surveying, and the work is done by professionals who are able to plot any land they like. They can do the work outside on any land, and they can show how big all the areas are for the homeowners or developers. They are scientists, but they do very practical work for everyone.
