3D Laser Scanning Services: The Evolution of Mobile Mapping in Surveying
Promising Technology for Surveying
Harald Saeger is the founder and CEO of NavVis, a company specializing in 3D mapping and indoor navigation technologies using 3D laser scanning services. In this article, Harald explores the different surveying technologies that have been developed over time and how they can be used complementary to each other.
The history of surveying is a long and fascinating one. Surveying techniques have evolved significantly over the centuries, from early methods like triangulation to more modern techniques like photogrammetry. Each surveying method has advantages and disadvantages, and no single approach is perfect for every situation.
One of the most important considerations when choosing a surveying method is the accuracy required. High accuracy is essential for some applications, such as mapping large areas or measuring distance. Other applications, such as measuring the height of a building or determining the contours of a piece of land, may not require such high accuracy.
Another important consideration is the time required to complete the survey. Some methods, such as triangulation, can take a long time to set up and execute. Other methods, such as GPS, can be much faster.
The Advent of 3D Laser Scanning Services
GNSS paved the way for 3D scanning. Why? In the past, GNSS advocators were careful not to oversell the technology and create unrealistic expectations. The potential for GNSS-based 3D scanning was immediately apparent to those in the industry and was sold out as such.
While GNSS has delivered some of its promises, it has also fallen short in others. But overall, it has been a positive development for the 3D scanning industry. There are still many issues to be worked out with GNSS-based 3D scanning, but it has a bright future.
Many new and exciting technologies are on the horizon for the surveying industry. 3D scanning technology is becoming increasingly affordable and accessible. The technology can help create highly detailed 3D models of survey sites, making it easier to identify potential problems or hazards. 3D laser scanning services can also help create virtual reality simulations of survey sites, which can be used for training or planning purposes.
Another promising technology is drone-based surveying. This technology can revolutionize how surveys are conducted, making them faster, more accurate, and more cost-effective.
Drones can also survey inaccessible or dangerous areas, such as disaster zones or hazardous waste sites, to improve site safety and increase mapping efficiency and accuracy. With these advances, surveying will become more efficient, accurate, and cost-effective, making it an even more essential tool for businesses and organizations.
