Geomatics Division

The Geomatics Division (GMD) carries out research and development activities in two main areas of Geomatics. The first one is the area of positioning and navigation, which is focused on the estimation of the position and attitude of sensors and objects. The second one is the area of remote sensing, which involves earth observation through images and data collected by sensors on board of satellites and aircrafts, and ground-based sensors.

GMD has two Departments:

The RSE department conducts research and development activities in the analysis and exploitation of data coming from spaceborne, airborne and terrestrial remote sensing sensors for a wide range of applications. The activities of the RSE Department involve: (i) exploiting data acquired by different types of sensors, both active and passive; (ii) employing a wide variety of data processing and analysis techniques; and (iii) developing different types of scientific and technical applications. The RSE activities can be classified in three main lines. The first one is satellite Synthetic Aperture Radar (SAR) interferometry for deformation measurement and the generation of Digital Elevation Models (DEMs). The second one is ground-based SAR and Real Aperture Radar for deformation measurement, DEM generation and structural vibration monitoring. The third one includes a miscellaneous of activities based on various remote sensing techniques, including terrestrial laser scanner, lidar, radiometry, microwave sensors, etc.

The GEON Department does research on static and kinematic estimation of navigation states, mainly position and attitude. This includes precise positioning and navigation with inertial navigation systems, global navigation satellite systems and imaging sensor orientation and calibration. The technologies currently used by the group are satellite navigation, inertial systems and digital image/ranging sensors. The GEON activity involves five main areas: (i) precise and robust integrated navigation; (ii) precise and robust kinematic positioning and trajectory determination; (iii) image matching and feature extraction; (iv) new platforms and paradigms for high-resolution geodata acquisition; and (v) precise and robust sensor orientation and calibration.
