4Indoor, an innovative 3D measuring and visualizing real estate company based in Amersfoort, has successfully created an accurate digital twin of the medieval Koppelpoort gateway using a NavVis VLX mobile mapping system. The company wanted to digitally capture the historical buildings in their beautiful city, and the Koppelpoort, a unique combination of a land gateway and a water gateway, was the perfect location.
Using the NavVis VLX mobile mapping system, the company created a high-quality 1.2GB point cloud and over 850 panoramic HD images of the gateway, completely digitizing the premises.

The point cloud, comprising billions of points, allowed them to create as-built floor plans and sections, giving the building owners remote access to the digital assets using any standard web browser on a laptop, tablet, or smartphone through NavVis IVION.
The Koppelpoort gateway is part of the second ramparts of Amersfoort and was constructed between 1380 and 1450. It is a unique and significant historical site in the Netherlands as it was used to regulate the flow of water from the River Eem into the city center and to admit or stop travelers via its combined gate.

By creating this digital twin, 4Indoor has captured a piece of Amersfoort’s history for future generations. The company prides itself on its passion and pleasure in helping air jordan 11 columbia customers with their digitization strategies. The digital twin solutions enable users to make better operational decisions, increase productivity, streamline business processes, and improve profitability.
In conclusion, 4Indoor’s innovative use of technology to create a digital twin of the Koppelpoort gateway in Amersfoort is an impressive achievement that showcases the power of digitization in preserving historical sites for future generations.
