Seminar on Geodetic Control Networks in the Emilia-Romagna Region

The seminar has been organized by the University of Bologna to be held on 05 July 2017 in Bologna.

Speakers from both the academic field and public administrations, that are governing the Emilia Romagna region, will introduce the state of art of the existing geodetic control networks, their criticalities and future projects regarding the networks.

Among them, TRE ALTAMIRA has been asked to illustrate the use of satellite studies to monitor the territory and its infrastructures.

The ARPA Agency of Emilia Romagna has been employing TRE ALTAMIRA’s InSAR measurements for calibration and validation with GPS data since 2006.
The alluvial plain sector (Po Plain) of the Emilia Romagna region in northern Italy is a rapidly subsiding sedimentary basin due to both natural and human-induced phenomena (e.g. water withdrawal was particularly intense during the second half of the 20th century). In 1999, ARPA Emilia Romagna and the Department of Civil Engineering (DICAM) of the University of Bologna established a network of 2,300 leveling benchmarks connected to 60 GPS marker points over the entire regional territory (Bitelli et al., 2000). InSAR was introduced in 2006 to update their subsidence map after calibration and validation with data from 17 GPS stations. The latter has enabled to obtain a homogenous subsidence map at a regional scale with “absolute” velocity data with respect to the ITRF (International Terrestrial Reference Frame). The combined use of InSAR and GPS can help regional authorities to plan actions aimed at ensuring the rational use of natural resources in Emilia Romagna.
