Marine Laser Scanning

In the fourth quarter of 2017 at the Faculty of Civil and Environmental Engineering at the Gdansk University of Technology, a project titled “Implementation of 3D laser scanning measurement procedure from a vessel” was completed.

The contractor of that project was Apeks Company from Gdansk, Poland. The team at the Department of Geodesy has developed a procedure for acquiring geodetic data from a platform, mounted on vessels moving on a river and sea.

As a part of analysis, a series of scan laser data of the sea coast, quays and engineering structures from the Motlawa river, Martwa Wisla river and Baltic sea were made.

Laser scanning services is becoming more popular these days. Rapid collection of spatial data finds applications in many fields for example in construction, geodesy, architecture, etc.

The procedure describes the method of using the Riegl VMZ-400 system to conduct scanning from a vessel with accuracy of scanned data not exceeding 10 cm (according to the Regulation of the Minister of Internal Affairs and Administration of 9 November 2011 on technical standards for performing geodetic situational and altitude measurements and the development and transmission of the results to the geodetic and cartographic resources).

Riegl VMZ-400 is a hybrid system. This means that it can be successfully used as a terrestrial and mobile laser scanning system. The analysis describes a procedure that allows the system to work on a vessel. In addition, the Apeks company is involved in projects related to environmental protection, that is why this product could provide high quality data in relatively short time and be used as a basis for degradation analysis. One of the products, that the Apeks company could guarantee is a numerical model terrain or 3D models.

It has to be mentioned that Apeks company could implement this method on the European and the Global market, not constraint only to the Polish market.

The head of the project was PhD Jakub Szulwic, the Main Contructor was MSc. Paweł Tysiąc. The procedure was developed by a team: prof. Marek Przyborski, PhD Katarzyna Bobkowska, PhD Artur Janowski.
