In this case study you will discover how Terra Modus, a company specialising in 3D laser scanning and photogrammetry, tackled the challenge of measuring the largest stormwater system in Lithuania. Conventional methods would have taken 5 years, but by using high-end laser scanners, bespoke hardware and their own software Undet, they were able to overcome numerous technical challenges, including limited access to the manholes and new method of georeferencing. In the process, improving productivity tenfold (from surveying 8 to 80 manholes per day) and completing this unique project in just 6 months.

When a complex government reconstruction project required a complete 3D model, Terra Modus, a company pioneering reality capture in Lithuania, used a combination of Trimble laser scanning technologies to save valuable time. The resulting pre- and post-construction 3D model was critical in helping identify design problems and significant discrepancies in the as-built construction, also providing an as-built of the new exterior to use for future maintenance and operations.

• Complete interior and exterior scan of an existing 6,310 square meter structure
• The building exterior was scanned by two people using two scanners in just six hours
• Each floor model took three days total, including data collection
• Revealed that each of the building’s five floors was 5 cm higher than the design indicated, significantly impacting prefabricated element

Digitization of such objects and their sustainable management with modern information systems is an important part of the activities of every company operating in the industrial and infrastructure sectors. Laser scanning is usually required when reconstruction or renovation work is planned, and the cost of an error is high. Infrastructure scanning in oil refineries and other objects in the energy sector, water supply and wastewater treatment facilities – are just some of the projects we carry out.

Each cultural heritage management project is unique. After assessing the needs of each client, the Terra Modus team prepares the information needed by designers and architects from the laser scanning data, so that the preparation of cultural heritage management projects is carried out knowing the exact situation of the object in the digital space.

The goal of digitizing art ​​is not only to transfer unique and valuable objects of cultural heritage into digital form, but also to properly prepare for restoration works. Cultural heritage institutions protect valuable heritage, which is important for the preservation of the identity and cultural specificity of each state and the development of art.

3D laser scanning is one of the newest technologies used in measurement taking, allowing to quickly collect large and extremely accurate amounts of 3D information about large-scale objects and their surrounding environment, and to transfer this data to improve acoustic and light projection modelling work before reconstruction.

Objects and items of cultural importance ​​unearthed during archaeological research are recorded with 3D laser scanners or the photogrammetry method. With the help of millions of points, not only are the exact shape and colors of objects recorded, but also the surrounding territory and buildings. This allows for a more accurate reconstruction of the historical image of the territory and possible integration into the planned renewal of the territory.

LIDAR scanning from an unmanned aerial vehicle is widely used in spatial planning and design to capture the dimensions, changes or other data of a given area. The results obtained during scanning are more detailed than when using electronic total stations or currently widely used GPS/GNSS receivers. The recorded information is very clear and perfectly understandable, so that specialists can correctly decipher it and use it in the later stages of projects.

UAB “Terra Modus” successfully continues the search for foreign business partners and export development by presenting its products at international exhibitions abroad. In target export markets, potential customers are introduced to the innovative and competitive “Undet” services.
