Revolutionising Surveying with 3D Services: Accuracy and Insights
Surveying is a very important part of many different kinds of projects. Whether you’re building a brand new building and need to understand a plot of land’s contours or you’re examining an existing structure, experienced NZ surveyors are your key to accurate results and easy-to-understand visual aids.
As we continue to develop newer and better technologies, the world of surveying has transformed quite a bit in recent years, leading to more efficient ways to collect data about land and structures. Among the most notable developments is the rise of comprehensive 3D services, which have completely revolutionised surveying. No longer will hardworking surveyors have to gather all of their data solely through physical means; now, we can use incredible technology to make each surveying task faster and more successful.
These modern techniques, such as terrestrial laser scanning, mobile laser scanning and Aerial LiDAR, offer exceptional accuracy and insights. They’re indispensable tools for modern surveyors, thus making them beneficial for clients as well.
The Remarkable Power Of 3D Laser Scanning
3D laser scanning is a complex process that captures the precise shape and dimensions of a plot of land or an object, allowing surveyors and clients to view large structures or objects in an accurate way. Like traditional surveying, this data will enable clients, architects, engineers and any other parties involved to shape their designs and work according to the specific contours of the land or structure they’re working with. This accuracy will help to avoid time-consuming and expensive mistakes, keeping projects streamlined.
Surveyors can create point clouds using a combination of scanning technologies, such as terrestrial and mobile laser scanners. These point clouds, or detailed three-dimensional representations of the scanned environment, can be used to create accurate visual aids like 3D models.
Terrestrial Laser Scanning. Terrestrial laser scanning involves using stationary laser scanners that are positioned on the ground at the area that needs to be surveyed. These scanners emit lasers that bounce back after hitting a surface, capturing millions of points per second and getting a digital understanding of a physical piece of land or object. This method is particularly ideal for buildings, landscapes and infrastructure.
Mobile Laser Scanning. On the other hand, this method involves mounting laser scanners onto moving platforms, such as vehicles or drones. This method allows for fast collection of data over large areas. The mobility of these scanners allows skilled surveyors to cover more ground quickly while maintaining high levels of accuracy. Driving a vehicle or piloting a drone means that stationary scanners won’t need to be repeatedly retrieved and set up, making this method better for larger projects.
Aerial LiDAR. Aerial LiDAR, or ‘ Aerial Light Detection and Ranging,’ is a modern sensing method that uses laser pulses to measure distances from an aircraft to the Earth’s surface. This method is particularly effective for mapping large and inaccessible areas, other areas that would otherwise be difficult to cover with the previous two methods. It’s generally used for areas like urban landscapes, forests and remote spaces.
What To Know About The Benefits Of 3D Surveying
There are so many reasons why these advanced methods are becoming the norm for surveying in New Zealand, including these many benefits:
Enhanced Accuracy. Of course, one of the top priorities of land surveyors is to capture accurate and precise data - and one of the most significant advantages of 3D laser scanning is the ability to consistently provide enhanced accuracy. Traditional surveying methods often involve manual work, which can open the door to human errors. Conversely, 3D services utilise modern digital tech to accurately capture millions of data points in a mere fraction of the time it would take a human.
Improved Visualisation. The detailed point clouds and 3D models generated by these technologies offer improved visualisations of the surveyed area. These advanced models can be viewed and manipulated from different angles, providing surveyors, clients and all involved parties an easy way to fully view the land or object in question. This visualisation will allow everyone to make informed decisions moving forward.
Increased Efficiency. Efficiency is a very important part of any kind of project. Proper time management is vital, so you want your surveyors to be able to complete their jobs efficiently without wasting too much time but also without cutting corners to work faster. 3D laser scanning is the perfect answer to speeding up work without sacrificing quality, and it typically requires fewer resources and time to collect and process data.
Versatility And Flexibility. The versatility of this impressive technology makes it suitable for a variety of applications, such as surveying empty land or examining an existing building.
