Land is surveyed for several different reasons, one of which is for residential land. Lots of people are familiar with this type of land survey and it is primarily used for property boundaries. These land surveys can be vital in resolving boundary disputes or when someone is purchasing land to build property on. They are also used for the purposes of applying for a mortgage. However, there is more to residential land surveys than meets the eye and it is not just about measuring the boundary. The surveyor will spend a considerable amount time researching and plotting the individual boundary for each property. They will search for records relating to the property such as title deeds, land registry and also investigate any other official records that are pertinent. This can be hugely important when for instance a piece of land is sold for the development of numerous new homes and a number of years have passed since the last survey was done. It is essential that the boundaries are correctly recorded at this stage in order to avoid disputes in the future.
When the surveyor has proof of the property’s boundaries, they will then be able to take measurements of the land which will determine whether the current boundary is in conflict with the boundary which was previously recorded. Often, stakes will be used as marker points which will make future surveys easier and give accurate points. Measurements are then taken with an electronic device called an electronic distance measurement or EDM but can also be done the old fashioned way, with a transit and a tape measure. These days GPS can also be used but the results are not as accurate as those produced using the more traditional methods of obtaining readings. The surveyor will generally make several measurements to give an average, then, using these results will be able to establish a true position for the boundary. On completion of the measurements, the land surveyor will then look at the placement of the stakes that were used for measuring points to see whether there are any differences between this survey and the previous records. It is important that proper records are kept and kept at every stage so that if there are any changes or differences, it is possible to make accurate checks.
When the land survey is done the property lines that have been recorded by the licensed surveyor then becomes the legal boundary for the property. Normally, there is no difference in this boundary line to that of the last one but sometimes this is not so. If there is a considerable difference, something has changed and that needs to be investigated. This is why having a house survey done before you purchase a property really can pay off as it will give you peace of mind before you make the decision. You can be confident that your boundary is legal and that there is no territory dispute. Land surveyors produce their surveys using maths, physics, geography and geometry as well as law and the ability to read maps accurately.
