Wiesbaden's High-Tech Aerial Survey to Map the Entire City by 2026

Wiesbaden is set to undergo a detailed new survey covering the entire city. The project, led by the Civil Engineering and Surveying Office, will use aerial photographs and advanced LiDAR scanning. Work is scheduled to run until April 2026, with flights planned for both day and night.

The survey will combine high-resolution cameras and laser technology to map the urban area. Cameras will capture vertical and angled images from all four directions, reducing the need for on-site inspections. These images will help track changes over time with greater accuracy.

LiDAR scanning will take place at night, while aerial photography happens during the day. The night flights have been coordinated with German air traffic control to ensure smooth operations. Residents may notice some aircraft noise, but officials say the benefits outweigh any minor disruption.

The collected data will support urban planning, environmental management, and land registry updates. It will also create a digital twin of Wiesbaden, giving the public access to detailed 3D models. These models will assist in flood protection, visibility studies, and visualising future construction projects.

The survey will provide precise elevation and surface data for the city. However, no timeline has been announced for when the processed 3D information will be available online. The project aims to improve decision-making with up-to-date spatial information.
