How to Locate Survey Pins
Survey pins are an essential tool in the field of land surveying, providing a precise and reliable method for marking property boundaries and other important locations. Whether you are a professional surveyor or an amateur enthusiast, knowing how to locate survey pins is crucial for accurate measurements and documentation. In this article, we will discuss various techniques and tips to help you locate survey pins effectively.
First and foremost, it is important to understand the types of survey pins used in the field. The most common types include metal pins, plastic pins, and concrete pins. Each type has its own characteristics and applications. Metal pins are durable and can withstand harsh weather conditions, while plastic pins are lightweight and less expensive. Concrete pins, on the other hand, are designed to be embedded in the ground and are used for permanent marking.
To locate survey pins, start by gathering the necessary equipment. This typically includes a compass, a tape measure, a pin pointer, and a GPS device. The compass helps you determine the direction of the property line, while the tape measure allows you to measure distances accurately. The pin pointer is a tool specifically designed to detect the presence of a survey pin, and the GPS device can help you locate the exact coordinates of the pin.
Begin by identifying the approximate location of the survey pins. This can be done by examining property maps, aerial photographs, or by asking local authorities for information. Once you have a general idea of where the pins might be located, use the compass to determine the direction of the property line.
Next, use the pin pointer to detect the presence of a survey pin. Hold the pin pointer close to the ground and move it slowly in the direction of the property line. The pin pointer will emit a sound when it comes close to a survey pin, indicating its presence. If you are using a GPS device, make sure it is set to the correct coordinates before starting your search.
Once you have detected a survey pin, use the tape measure to measure the distance from the pin to the property line or other important locations. Be sure to account for any curves or irregularities in the property line. Record the measurements and take note of any landmarks or other features that can help you identify the pin’s location.
In some cases, survey pins may be buried deep in the ground or covered by vegetation. To locate these pins, you may need to dig or clear away the vegetation. Be cautious when doing so, as you do not want to damage the pin or the surrounding area.
Lastly, always keep a record of your findings. Document the location of each survey pin, including the type of pin, its distance from the property line, and any other relevant information. This will help you in future reference and ensure the accuracy of your survey.
In conclusion, locating survey pins is a crucial skill for anyone involved in land surveying. By understanding the types of survey pins, gathering the necessary equipment, and using the right techniques, you can effectively locate survey pins and ensure accurate measurements. Remember to always document your findings and be cautious when searching for buried pins. With practice and patience, you will become proficient in locating survey pins and contribute to the success of your surveying projects.
