RICERCA ITALIANA     

The geomatics in support of the actions of Government of the territory

Università degli Studi di Bologna

Abstract

The control of the territory from the Public Administration (PA) and of the Local Bodies, both in terms of monitoring and knowledge and management of the territorial data, is a living matter in an epoch where information are acquired in greater and greater amount and made available in increasingly short times. Particularly, Geomatica makes available acquisition and handling techniques, specifically addressed to the territory monitoring, to the geographical information updating and to the preservation of the public heritage, that manage data coming both from ground surveys and from aerial and satellite platforms.
Therefore, the research activities scheduled in the project are intended to be a meeting point between the new possibilities offered by Geomatica and the need, from the PA and the Local Bodies appointed to the government of the territory, of knowledge of the Italian territory and of its dynamics. Particularly, the new techniques (real time geodetic precision positioning networks, airborne and terrestrial Laser scanning, remote sensing, high resolution images, Data Base and Geographical Information Systems) supply more and more accurate and sophisticated products that, for a correct characterization of the different problems which they are called on to answer, must be used in an appropriate way and made fully integrated.
A fundamental element for the interoperability of the territorial information, is the possibility to refer them all to the same >>>

Research Objectives

The scope of this research is to realise procedure and products that can be used by Authorities involved in the territory management. The definition of corrected standard procedure, tools and the definition of instrument for the certification of real time positioning services will help the Authorities in the knowledge and management of the territory. These results will be obtained by the investigation of some of the innovative aspects concerning the Geomatic such as Geodetic Network for precise real time positioning, Laser scanning, Remote sensor, Data Base and GIS.
Scecific objectives that play together for the main goal are followed explained:

INTEROPERABILITY BETWEE REFERENCE FRAMES
The final scope of our project is t conceive rigorous procedure for transformations from cadastral coordinates to Gauss’ ones as referred to Roma 40 and WGS84 systems.
We foresee to make up a software proper to the said aim, starting from coordinates and maps in raster or vector type.

LOW COST GNSS EXPERIMENTATION FOR THE BUILDINGS MONITORING
The research try to realise geodetic network constitute by a reference GNSS receiver located in a stable structure and more GNSS low cost receivers in some buildings over a unstable area. All the acquired data by all the receivers will be collected in a Local control centre for the real time processing and archiving. In this way we can monitor the positions of all the buildings in real time respect >>>

First Results

U.O. BOLOGNA
The results are expected on the following topics:
1.Experimentation on low cost systems for buildings monitoring.
Making of a testing network made of three-four test points for real-time control on the relative movement of buildings located in landslide area.
Running continuous measurement and data acquisition for at least six months.
Proposal of procedures for data analysis and reduction of noise measurement.
2.Experimentation on NRTK networks for monitoring.
Study on integration of monitoring subnets in a NRTK structure. Using the R3 network: project feasibility, prototype [Action influenced by the continuing availability of System Manager R3]
3.Software making
Realization of a software for the analysis of obstacles to the visibility of various constellations of satellites, including Galileo, urban field; data validation of Operational Unit Napoli
Production of tools for the analysis of time series acquired from network monitoring in order to remove the effects of noise able to mask the presence of any movements.
4.Information System intended to monitor culture in an area of Emilia-Romagna,
Implementation of Information System.
Multi-temporal analysis through ASTER image.
5.Evaluation and analysis of natural disasters of different kind through remote sensing

National and international background

The government of the territory is a central element in political activity and management of the public administration and to fulfill its action needs cognitive tools more sophisticated in reference to geography information.
Geomatics in its various subdivisions- Cartography, Positioning, Information Systems, Data Base, Geodesy, navigation is able to make available new and with great efficiency tools for the metric and qualitative knowledge of the territory.
The needs of government land are underlined by specific indications of the European Union.
Actions like INSPIRE tend to standardize on a European level data related to space and their management systems.
In Italy it is very recent the presentation of legislative initiatives focused on the issue of government land and about models to be used for this purpose:
Law Project by Senator Sodano and other initiative informed on February 2007 the 7th, with reference n. 1298. “Principles on landscape planning and implementation and receiving of of Directive 2001/42/EC of the European Parliament and Council dated 27th June 2001 on the assessment of the effects of certain plans and programs”;
Law Project by Senator Ronchi and other initiative informed on July 2007 the 7th, with reference n. 1691. “Standards for the Protection and the government of the territory and the government delegation in the area of urban design taxation and estate and for the reorganization and coordination of >>>
