Land surveying is an integral part of construction, land development and management and environmental preservation. The job of land surveyors is to collect accurate and precise measurements of the land's contour, shape and features to aid in architectural and engineering designs. With the advent of technology, the traditional tools of surveying, such as measuring chains, tapes and compasses, have been replaced with sophisticated gadgetry that is more accurate and efficient. So, what is some of the latest technology used by land surveyors, and how can it help you?
Global Positioning System (GPS)
This technology has revolutionised the way land surveyors collect measurements with greater accuracy and precision than traditional methods. GPS uses a network of satellites that communicates with handheld GPS receivers or rovers to determine the exact location of survey markers or reference points on the land. GPS is not only faster but can also collect a vast amount of data that can be transferred to a computer for analysis.
Light Detection and Ranging (LiDAR)
This is a remote sensing technology that uses laser light to measure the distances and heights of objects on the land surface. LiDAR sensors are mounted on helicopters or drones that scan the land's surface and create high-resolution 3D maps. These maps not only provide precise land measurements but can also be used for creating elevation models, floodplain mapping and monitoring vegetation growth.
Geographic Information System (GIS)
GIS is a digital system that gathers, manages and analyses geospatial data. Land surveyors use GIS for creating maps, identifying land use changes and detecting environmental hazards. GIS technology helps surveyors to integrate various data sources, including LiDAR and GPS data, for better analysis and decision-making.
Robotic Total Station
This is a surveying instrument that measures angles and distances between reference points on the land surface. The traditional total station requires manual adjustment of the instrument by the surveyor. The robotic instrument is mounted on a tripod and has a motorised system that automatically locates and measures reference points. The surveyor can control the total station from a remote location, making it easier and safer to use.
Virtual Reality (VR)
VR technology is being used by land surveyors for creating 3D models of construction and land development projects. Using VR, surveyors can create interactive models that simulate different scenarios of architectural design. This technology helps surveyors to identify potential safety hazards and design flaws before they become a reality.
What to Do Next
The latest technology used by land surveyors has made the measurement and analysis of land more accurate and efficient. So, why not take advantage of this up-to-date tech and bring in an experienced land surveyor to help you with your next project?
