GReD s.r.l. – Geomatics Research & Development Spin-off del Politecnico di Milano Projects

Heli-dem project The target of the Heli-dem project ( is the computation of a new Digital Terrain Model (DTM) That includes all the available information over the Alpine And sub-Alpine area between Italy and Switzerland. The Project is co-funded by FESR and includes the following partners: Landscape and Urban General Directorate of Regione Lombardia; Geomatics Laboratory of the Department of Environmental, Hydraulic, Infrastructures and Surveying Engineering (DIIAR) at Politecnico di Milano; Fondazione Politecnico di Milano; Department of Land Territory and Geotechnologies (DITAG) at Politecnico di Torino; Department for Strategic Programming, Spatial Policies and Housing of Regione Piemonte; Department for Environment Constructions and Design at the University of Applied Sciences and Arts of Southern Switzerland (SUPSI). In the framework of this project, GReD is supporting Politecnico di Milano for the merging of the Swiss geoid CHGeo2004 with the Italian one ITALGEO05, by exploiting GOCE observations and the EGM08 global gravity model.

The project kick off was on February 15, In the framework of this project, GReD is supporting Politecnico di Milano in the development of new algorithms for precise satellite positioning and for the integration of local gravity models with the global ones derived from the GOCE mission. The target of the GAL project ( is the study and the development of a new methodology for the determination of high-resolution local gravity models by airborne gravimetry. The proposed methodology is now feasible by exploiting a variety of different surveying technologies, such as GNSS observations (GPS and Galileo), EGNOS and inertial units. The computed models are then combined with gravity data coming from the ESA satellite mission GOCE. The project has been proposed by the GAL Consortium, which comprises the following partners: GAL project

Regional & national networks Network adjustment of regional and national networks (GPS Lombardia, Rete Lazio, Italpos and RDN Networks) to routinely compute very precise permanent GNSS station coordinates in a single reference frame.

Gravimetric applications GReD is working with the Department of Environmental, Hydraulic, Infrastructures and Surveying Engineering (DIIAR) at Politecnico di Milano to considerably improve performances of airborne kinematic gravimetry/gradiometry in terms of accuracy and spatial resolution of the retrieved local gravity field through the developing of new algorithms and merging all the routines in a unique software. The combination of different observations of the gravitational field is a key task for some industry, such as mining and oil & gas exploration, and it will allow for instance to have preliminary information on the gravitational field in a local region without any particular acquisition campaign or to have a refined grid if airborne and ground data are available in the area. The major goal of the project is the implementation of a software able to combine different gravity observations in a multi-scale approach and to deliver a local grid of free air or bouguer gravity anomalies.

Mapping urban underground The target of the mapping urban underground services (MUS project) is to develop a prototypal solution to carry out three-dimensional GEORADAR surveys over large areas in urban environment. The city underground is in fact strongly man-made by several networks of services and nowadays there is not a sufficient knowledge of the actually placed infrastructures. This implies a significant difficulty both in the maintenance of existing networks and in the realization of new ones. In the framework of this project, GReD is supporting the Department of Civil and Environmental Engineering (DICA) of Politecnico di Milano in the development of the GEORADAR positioning system based on low-cost multi-antenna GPS. Although with degraded performances, the low-cost receivers can in fact operate in hostile urban environment with a poor satellite visibility and a multi-antenna system, in addition to guaranteeing a greater robustness, allows to estimate the attitude of the vehicle with the GEORADAR on board.
