Survey Legend
Land surveying is a very significant task in the real estate industry. It requires a high level of precision and expertise to ensure that the land measurements and boundaries are accurate. As a land surveyor, one of the most important aspects of the job is calculation, which involves the use of various mathematical formulas to determine land boundaries, areas, and volumes.
One tiny miscalculation can result in significant problems, which can lead to costly legal issues. Therefore, it's essential to avoid some common surveyor calculation errors. In this article, weā€™ll discuss some of the most crucial errors a land surveyor must avoid to ensure accuracy in their calculations.
Common Mistakes to Avoid in Land Surveyor Calculations

Using Inaccurate Instruments

For any land surveyor, having accurate and up-to-date equipment is crucial to accurately measure and calculate land boundaries, areas, and volumes. However, even the most sophisticated and advanced instruments can produce inaccurate measurements if used improperly. Surveyors should ensure they're using the appropriate equipment and measuring devices for the job. Using outdated or faulty equipment can lead to inaccurate measurements, which can lead to significant errors in land survey calculations.

Failing to Account for Curved Surfaces

Most land surveyors measure the surface of the earth, which may pose a problem in calculations when the earth's surface is curved. When calculating areas and volumes, surveyors may mistakenly neglect the earth's curvature, resulting in inaccurate results. Surveyors must take into account the curvature of the earth's surface while measuring distances, areas, and volumes, especially when working on larger projects. This ensures that measurements and calculations are accurate and reliable, which helps avoid costly legal disputes or project delays.

Ignoring Changes in Elevation

Changes in elevation are another factor that surveyors must consider while making measurements and subsequent calculations. They may be caused by slopes, terracing, contouring, or discontinuity within the land area. Failing to account for changes in elevation can lead to incorrect calculations, leading to issues such as underestimating or overestimating the land area's volume. Surveyors must take precise measurements of the elevation changes and incorporate them into their calculations to provide accurate results.

Not Accounting for Legal Descriptions

When it comes to land surveying, legal descriptions are essential in identifying the boundary lines accurately. A surveyor must understand the legal descriptions applicable to the land area they are surveying. Some land descriptions may have been created many years ago and might not be up-to-date with the current state of the land area. This can result in boundary line errors if not appropriately identified. It's crucial to double-check legal descriptions and ensure accuracy before making any calculations on the land area.

Not Recognizing Errors

Even the most skilled, experienced land surveyor can make mistakes and overlook errors while measuring the land area. When errors are not recognized and corrected, they can have serious legal consequences, which can lead to costly lawsuits. Experienced land surveyors should be trained to detect potential errors and double-check their work to ensure accuracy. Land surveying is a technical profession that requires a high level of attention to detail, so surveyors should perform and double-check their work to avoid any potential legal issues.


The crucial role of a land surveyor cannot be understated in real estate transactions. Surveyors must ensure that their calculations are precise and accurate to provide legal protection for their clients. Errors in calculations can lead to significant legal disputes that may result in expensive litigation for both parties involved. As a result, surveyors must take care to avoid common mistakes, such as the use of inadequate equipment, failure to recognize errors, and neglecting legal descriptions. Land surveyors must understand the critical factors and considerations that go into calculating land boundaries, areas, and volumes while taking care to avoid errors and maximize precision. In conclusion, surveyors should always adhere to the highest professional and ethical standards, be diligent, and remain up to date with the latest technologies and regulations governing land surveying.
