3D Laser scanners are the go-to measurement tools for land surveyors due to their accuracy. ,
Mapping a property or space can take a considerable amount of time and money, but 3D laser scanners make surveying fast and accurate, greatly reducing field time and helping surveyors stay within budget by preventing rework.
In addition to our traditional land surveying services, Wellington Land Surveying also offers 3D Laser Scanning services. Sometimes referred to as High Definition Surveying (HDS) or Terrestrial LiDAR, Laser Scanning is a state-of-the-art technology that allows us to remotely collect large amounts of accurate data that would normally be difficult or impossible to collect by conventional land survey means.
Laser Scanning provides a safe alternative to surveying in active work zones such as roadways and airports as well elevated objects such as bridges, buildings, and material stockpiles.
Once a site is scanned and processed, the data can check and or be re-checked on a desktop computer from any location. A complete 3D model of existing conditions can be created from multiple “scan” setups and used to verify designs prior to construction, as well as to identify clash interference between design elements and any actual structures.
3D laser scanning utilizes devices equipped with lasers to measure the physical world by capturing millions of measurements. The collected data is then used to generate polygon meshes or point clouds that represent the geometry of a physical object. In the land surveying business, 3D laser scanning is highly appreciated for its unprecedented range and speed, as well as its precision.
with professionals around the world turning to the technology to improve their data collection and project outcomes. However, 3D laser scanners are more than just tools to measure vast distances and gather pin-point information on as-is conditions – the technology is a solution to many of the challenges land surveyors have encountered for years.
3D Laser scanning is a relatively new technology, having been used as a precise survey instrument only since 1998. Now, it is quickly becoming the new industry standard as a way to make very accurate measurements in complicated environments. This is precisely why using this technology is the best solution for measuring as-built conditions inside buildings.
This instrument collects survey data points at a rate of 50,000 points per second. It has an effective range of 400’ to 500’. With several “scan” setups inside a room or of a building, a complete 3D model can be made of the existing conditions. These models are then used to create 2D civil or architectural drawings, 3D computer models, and final survey documents.
