In professional land surveying, a ground-run survey refers to a specific method of collecting data for a topographic map. It’s a meticulous method of data collection that involves physically walking the boundaries of an area. For projects in Georgia, a state known for its diverse terrain, Georgia land surveying often still includes this technique for its accuracy.
Ground-run survey methodologies have been the industry standard for years. As such, they offer several key benefits that make them the preferred choice for specific situations.
While ground run surveys offer excellent precision and detail, they do have some drawbacks when compared to other methods like aerial or remote sensing:
Overall, ground run surveys are a valuable tool for detailed mapping of smaller areas, especially where accuracy and precision are critical. However, their limitations in terms of time, cost, accessibility, and data processing should be considered when choosing the right surveying method for a specific project.
LiDAR, short for Light Detection and Ranging, is like a super-powered ruler for the environment. It fires laser pulses like tiny explorers, sending them on a journey until they bump into objects or surfaces. By measuring the time it takes for these light scouts to return, LiDAR can calculate distances with incredible precision. This makes it a modern marvel in land surveyor’s tool kits, allowing for the creation of detailed 3D landscaping maps with unparalleled accuracy.
LiDAR scanning methods can be used in a variety of applications, from mapping the intricate topography of forests to precisely measuring the height of buildings. It can peer beneath the waves, creating underwater maps with stunning accuracy, revealing shipwrecks, coral reefs, and other hidden wonders, creating underwater maps with stunning accuracy. LiDAR scanning can be coupled with other sensors and machinery, such as drones or self-driving cars, to provide views that were previously too difficult or impossible to capture.
LiDAR technology is fascinating and has impressive potential applications with and well beyond the scope of land surveying. Here are some of the ways LiDAR shines, making it a go-to method for surveyors.
Benefits of LiDAR Scanning
As amazing a technology as LiDAR is, it is not without its set of drawbacks which counterbalance its benefits.
Drawbacks of LiDAR Scanning
HOW CAN A LICENSED LAND SURVEYOR HELP YOU WITH BOTH LiDAR AND GROUND-RUN SURVEYING?
Whenever you have a property of any type or size that needs to be surveyed, particularly for construction projects and land purchases, a licensed land surveyor can be your trusted guide. They can help you determine what type of survey best suits your specific needs and what data-gathering methodologies are ideal for property.
● Large-scale projects. If you’re tackling a vast area like a highway construction project, a surveyor can utilize LiDAR to quickly capture the terrain’s intricate details, providing a comprehensive 3D model for efficient planning and decision-making.
● Rapid data acquisition. Need precise data fast? LiDAR’s high-speed data collection capabilities can expedite the process, saving you precious time and resources, especially for time-sensitive projects like disaster response or emergency planning.
● Accessibility and safety. LiDAR can safely map hazardous or difficult-to-reach areas like steep cliffs or dense forests, minimizing risk to human surveyors while providing crucial data for tasks like infrastructure inspection or environmental monitoring.
● Smaller, intricate projects. For smaller areas like a property line dispute or a building foundation, traditional surveying methods like theodolite and tape measurements offer unrivaled accuracy and control. This is crucial for ensuring precise measurements and avoiding costly errors, especially in legally sensitive situations.
● Detailed site investigation. Traditional methods allow for a meticulous examination of specific points, enabling the surveyor to identify subtle changes in elevation, underground utilities, or potential structural issues that LiDAR might miss.
● Cost-effectiveness. For smaller projects where budget is a concern, traditional surveying methods can be a more cost-effective option compared to the upfront investment required for LiDAR equipment and expertise.
● Expert advice. Your surveyor will act as a trusted advisor, analyzing your project needs and recommending the most efficient and cost-effective combination of LiDAR and traditional methods to achieve your desired results.
● Data integration. Surveyors skilled in both LiDAR and traditional methods can seamlessly integrate data from both sources, creating a comprehensive and accurate picture of your project area.
● Holistic approach. By leveraging the strengths of both approaches, your surveyor can provide you with a more complete understanding of your project site, enabling informed decision-making and maximizing the value of your investment.
Overall, both ground-run surveys and LiDAR scanning offer amazing opportunities for landowners, real estate developers, local municipalities and more. It’s important to be aware of the benefits and drawbacks associated with both methods before requesting either for a specific surveying project.
A licensed land surveyor is a valuable partner in navigating the complexities of land surveying. Choosing one with expertise in both LiDAR and traditional methods ensures you get the best of both worlds, helping you leverage the strengths of each approach for your specific needs. In the end, it will lead to accurate results, efficient workflows, and peace of mind in your project.
