Geomatics Engineering

Geomatics takes into account the following areas of research: 

  • Land surveying, 
  • GIS and navigation,  
  • Global-navigation satellite systems, 
  • Gravimetry, 
  • Photogrammetry and remote sensing. 

In general, we focus on applying theoretical methods and modes to solve specific problems. For example, monitoring influence of salt water on the ground stability in the Old City of Gdańsk, weather forecast, maritime application of gravimetric data or using so called “fast cameras” in the field of material strength, biomechanics and affective computing. We are conducting research both theoretical and experimental in the field and in the lab. We have one of the unique equipment capable of doing mobile experiments in gravimetry MGS-6. 

"Improvement of non-standard methods of statistical elaboration of geodetic observations in the process of determining displacements and deformations", this is the main research topic of the Advanced Geodetic Calculation Methods Group.  

Detailed research tasks of the group include: 

  • determination of displacements in unstable reference systems,
  • development of the Msplit concept - estimation in the elaboration of the results of geodetic observations,
  • application of Kalman filtration in determining the displacement of engineering structures,
  • developing the concept of elaborating the results of measurements obtained by the method of hydrostatic leveling,
  • estimation and prediction of random surface deformation using Total Least Squares Collocation. 

The Global-navigation satellite systems research group’s activities are focused on using precise products for developing observations from global navigation satellite systems (GNSS). The works are carried out in two main areas: strictly geodetic and for the needs of geophysical research. With regard to the geodetic applications of GNSS measurements, the team performs work related to the implementation of reference systems by precisely determining the position and velocity fields of reference stations, along with their detailed analysis.  

As part of geophysical research, the analysis of the earth's atmosphere are carried out. The team's work focuses on identifying and modeling ionospheric disturbances caused by geomagnetic storms. It allows for a better understanding of the emergence and propagation of existing disturbances and their impact on radio and navigation systems, e.g. by reducing the accuracy of the determined position. Ultimately, the analyzes are to be used to develop four-dimensional models of the ionosphere and to forecast phenomena with the use of machine and deep learning methods. 

The second area is the study of the troposphere. The GNSS technique is used in forecasting and researching dangerous weather phenomena and the progress of climate change is monitored. Numerical weather forecasting models are an additional activity of the team – see the METEOPG system (www.meteopg.pl).  

The main topics of the GIS Group are: 

  • Sensors and Systems for Vehicle Navigation 
  • Radar and Sonar Imaging processing 
  • Sensors and Sensor's Fusion in Autonomous Vehicles 
  • Remote Sensing in Vessel Detection and Navigation
