EXPERIUM PROJECT REFERENCE

Experium Delivers 3D Modeling Data of Observation Tower in Tampere, Finland to Support Urban Planning

Experium carried out survey-grade 3D documentation of Tampere Finland’s tallest observation tower at 168 meters. The project produced centimeter-accurate aerial data, providing Tampere City Planning with reliable 3D documentation to support urban development and geospatial analysis needs.

task

To produce highly accurate 3D data of the 168m observation tower ensuring complete structural coverage. The data must be suitable for digital 3D modeling to support Tampere’s urban planning needs.

challenge

Drone mapping the observation tower demanded coordination between multiple parties and careful flight planning and survey-grade precision due to its height, location, and operational environment.

  • Situated within Tampere’s busy district on the shores of Lake Näsijärvi, the site is encircled by pedestrian areas, amusement attractions, and public infrastructure, creating tight constraints for drone operations.
  • Standing 168 meters tall with a narrow cylindrical structure, the multi-section tower required uninterrupted coverage to avoid data gaps and to ensure survey-grade accuracy.
  • The rotating restaurant and observation deck added both vertical and horizontal complexity, demanding extremely precise data to provide reliable 3D modeling and urban planning support.

solution

Experium employed survey-grade drone mapping technology and structured flight planning to capture the observation tower with centimeter-level positional accuracy, delivering a dataset suitable for high-fidelity 3D modeling and urban planning.

  • The 3D modeling data capture was carried out within carefully selected time windows to minimize risks in the high-populated district, where pedestrian traffic, amusement rides, and public infrastructure created operational constraints.
  • High-resolution nadir and oblique imaging ensured uninterrupted coverage of the 168 m cylindrical tower, preventing data gaps and maintaining survey-grade accuracy across the full height of the structure.
  • The mission was executed within controlled urban airspace under coordinated approvals with aviation authorities, meeting strict technical acceptance criteria for data quality, model fidelity, and alignment.

outcome

The completed project by Experium delivered a high-precision aerial dataset of the observation tower. The results extended beyond immediate modeling needs, creating a long-term geospatial reference that supports development and ongoing infrastructure management.

  • A validated digital dataset of the full 168 m tower, captured with uninterrupted dimensional accuracy.
  • Centimeter-accurate aerial records integrated into 3D modeling, digital twin environments, and planning systems.
  • Reliable documentation for new construction, heritage preservation, and structural monitoring needs.
  • Safer and more cost-effective compared to traditional survey and inspection methods.
  • A permanent geospatial reference enabling reliable integration into future planning and asset management without the need for repeated survey campaigns.

HIGHLIGHTS

Summary

Experium’s 3D modeling data of the observation tower demonstrates how drone technology can generate long-term value from even the most complex urban landmarks, delivering accuracy, reliability, and practical benefits.
