If you have never had a land survey carried out on your property before, you may have doubts about how accurate the final report will be. However, qualified land surveyors take many steps to check for any errors before they publish their final report. Below is a guide to 3 things a land surveyor will do to ensure they produce an accurate survey.
When a surveyor has finished mapping a piece of land and its boundaries and features, they will then double check their results by repeating the survey in reverse order from the finishing point to the start point. Doing so allows them to detect any errors in measuring distances or recording the results. This double-checking ensures that the final report is accurate.
The second way that a land surveyor will check the precision of their measurements and notes is to carry out a mathematical check of the numbers on the list. By using a range of technical equations which have been developed since land surveying became a professional skill, it is possible for the contractor to evaluate how accurate the report is. If the land equations will not balance as expected, this suggests that a mathematical error has been made when carrying out the calculations. If the equation balances despite an error which has been discovered, then this suggests that the instruments used to take the readings were not properly calibrated. Either way, by using these equations, a land surveyor can check their work before producing a final report.
Margin of Error
Sometimes, a land surveyor may find it difficult to accurately measure and map terrain. For example, this may be because the terrain is difficult to access, such as if it is on the side of a very steep slope or because it is difficult to gain a clear line of sight between two points using an instrument. To compensate for this, all land surveyors work within what is known as an acceptable margin of error. The exact margin which is permitted will depend on the type of survey work which is being undertaken. For example, the margin of error will be larger when surveying a piece of agricultural land compared to surveying a densely populated urban plot. The surveyor will rely on several equations to calculate the acceptable margin of error and to work out if their measurements fall within it.
