If it compromises the functionality of the cultural property it becomes pathological and results in degradation. The monitoring\, carried out with the use of innovative technologies\, is a p reliminary tool to an effective planned maintenance activity and therefore preventive conservation. Regarding these aspects the Parco archeologico d el Colosseo took a strategic direction of a gradual transition from a plan of monitoring to a constant and planned conservation activity.\nThe monit oring project of the Parco archeologico del Colosseo (that started in a sy stematic way only in 2018) was inspired by the desire to build a sustainab le system of protection and conservation\, then allowing a proper tourism valorisation. With these objectives in mind\, the Parco archeologico del C olosseo has developed a static and dynamic monitoring project consisting o f five fundamental activities:\n1. a database of all the historical data o f the monuments\, together with the existing graphic and photographic docu mentation (namely digital documen-tation archive)\; \n2. visual monitorin g carried out by teams of technicians dedicated to the inspection and cont rol of monuments\, also thanks to dedicated app that will allow to send da ta to the central system\; \n3. satellite monitoring (historical analysis of the satellite data) going directly into the system and analysed in orde r to monitor possible ground deformation\;\n4. in situ monitoring from tra ditional geotechnical instruments\;\n5. experimental activities.\nBasicall y\, the project involves the creation of a multi-parameter system of perma nent control of the entire archaeological area\, with the associated indic ators of the level of risk\, based on the combined use of innovative techn ologies. \nIn this way\, the project will allow to plan\, in an effective and timely manner\, the necessary interventions for both ordinary and extr aordinary maintenance\, thus providing not only an operational tool\, but also a management system for the Park with a better use of its financial r esources.\nAs part of this monitoring project\, the Parco del Colosseo req uested the presence of experts from the Italian Space Agency (ASI).\nThe i nstrumental diagnostic tools are accompa-nied by satellite monitoring\, al ready tested in the past for a short period\, to obtain information on gro und displacements\, structures\, and buildings. The use of satellite SAR interferometry technique applied to COSMO-SkyMed images is combined with t he advantage of being able to use the archives of radar images that allow us to deduce\, in an extensive manner\, the evolution in time of more than twenty years of deformation processes. One of ASI's contributions to the monitoring project is to provide the images acquired by the COSMO-SkyMed s atellites. Synthetic Aperture Radar (SAR) satellite data are gradually use d for study applications and monitoring of cultural heritage\, through mul ti-temporal analysis based on change detection techniques and differential interferometry (DInSAR). COSMO-SkyMed Constellation offers ideal features for routine monitoring of cultural heritage and observation in emergency situations which have been the subject of several demonstration\, (pre-) o perational and scientific research projects over the last sixteen years si nce the mission was declared fully operational. COSMO-SkyMed is the ASI SA R constellation\, the only one in the world to be made up of 5 satellites operational (3 first generation and 2 second generation) in the X band\, c apable of providing very high spatial resolution images (up to 1m per civi l use)\, very high acquisition frequency (revisit times up to 12 hours)\, in any meteorological and light conditions. The use of satellite SAR inter ferometry technique applied to COSMO-SkyMed images is combined with the ad vantage of being able to use the archives of radar images that allow us to deduce\, in an extensive manner\, the evolution in time of more than twen ty years of deformation processes. For these reasons\, the Parco also cons idered fundamental the satellite historical analysis of the archaeological area\, carried out since 2010 until 2019. The satellite images\, provided by ASI\, were processed on commission by e-GEOS with interferometric tec hnique. The data thus processed fed the web-GIS platform of the Parco’s monitoring project.

Recent publications critically reviewing the specialist scientific liter ature highlight a significant level of maturity of satellite applications in this domain (Luo et al.\, 2019\; Tapete and Cigna\, 2019a)\, so as sate llite images collected from optical sensors have already become common dat a exploited by (geo-)archaeologists\, researchers and heritage experts. A t the same time\, Synthetic Aperture Radar (SAR) technologies are increasi ngly being tested and exploited\, also beyond the specialist image analyst community\, thanks to multidisciplinary collaboration between different p rofessionals (Tapete and Cigna\, 2017) and facilitated SAR data access giv en the increasing provision by space agencies\, also in “ready to use” formats (Tapete and Cigna\, 2019b). At European level\, the Italian ecos ystem undoubtedly represents an excellence\, given not only the long tradi tion in exploitation of innovative technologies for cultural heritage\, bu t also the space sector investments into both Earth Observation missions w ith characteristics of image acquisition that well suit the user needs and requirements for this application domain\, and initiatives promoting down stream applications and services development engaging small\, medium and l arge enterprises. In continuity with the past decade\, ASI continues laun ching and managing several initiatives for cultural heritage\, in particul ar along the following directions: \n• Undertaking scientific research a nd development\, also through real-world user-driven use cases\, e.g. demo nstrating the performance achievable using national assets such as COSMOSk yMed data (Tapete and Cigna\, 2019b\; 2020)\;\n• Supporting COSMO-SkyMed data exploitation in projects with Italian institutions (e.g. Ministry of Culture\, Archaeological Park of Colosseum)\, and activities devoted to d ownstream applications and services development (e.g. in Pompeii\, Capo Co lonna) (Virelli et al.\, 2020)\; \n• Promoting downstream by scientific\ , commercial and institutional users through the new programme “Innovati on for Downstream Preparation” (I4DP)\, wherein safeguard of environment \, cultural heritage and national landscape is among the key application d omains. \nThe present paper therefore will illustrate ASI’s contribution for cultural heritage\, alongside the current perspectives\, in light of the COSMO-SkyMed programme (upstream) and “Multi-mission and Multi-Frequ ency SAR” and I4DP programmes (downstream)\, the latter with particular focus on the initiative dedicated to scientific users (I4DP_SCIENCE) accor ding to the roadmap defined by Tapete & Coletta (2022). \n \nReferences \n Luo L.\, Wang X.\, Guo H.\, Lasaponara R.\, Zong X.\, Masini N.\, Wang G.\ , Shi P.\, Khatteli H.\, Chen F. et al.

The impact on infrast ructure monitoring was particularly significant\, also in light of the inc reased flow of SAR data collected in different radar bands and disseminate d by space agencies in these past years.\nASI’s COSMO-SkyMed constellati on operating in X-band is among the satellite assets that are mostly explo ited by scientific and commercial community to perform high precision and accuracy monitoring\, at high spatial and temporal resolution. Recent stud ies undertaken by ASI following “data exploitation” initiatives of COS MO-SkyMed data have highlighted an increasing use of these data to study a nd monitor bridges\, motorways\, railways\, pipelines and plants. Scientif ic proof of concepts and demonstrators have led to strengthening national and international expertise in the use of InSAR multi-temporal techniques\ , and paved the way for downstream applications and mature monitoring serv ices.\nAt the same time\, the global scale availability of C-band Sentinel -1 data has contributed to a further dissemination of InSAR techniques for infrastructure monitoring\, although the specialist literature has highli ghted the limitations due to spatial resolution\, as well as the need to c ombine different band SAR data collected at different resolution.\nFrom 20 21 to 2023\, through the “Multi-mission and Multi-Frequency SAR” Progr am (Tapete et al.\, 2022)\, ASI has supported R&D projects focusing on dat a fusion and post-processing techniques in the field of infrastructure def ormation monitoring. Benefits achievable through integration of multi-band SAR data (including L-band SAOCOM) have been demonstrated.\nIn light of t hese investments and the maturity of SAR data processing algorithms for ge neration of application products\, ASI continues their institutional missi on according to the following activities:\n• In the upstream sector of s atellite missions\, improving SAR sensors to achieve new observation capab ilities with COSMO-SkyMed Second Generation (CSG) satellites and facilitat ing the accessibility to long time series ensuring observation continuity\ ;\n• In the downstream sector of applications and services development\, promoting SAR data exploitation\, also in combination with navigation and telecommunications technologies\, through the new programme “Innovation for Downstream Preparation” (I4DP)\, wherein management and monitoring of structural stability of critical infrastructures is among the applicati on domains of recent funding and projects initiation.\nThe present paper t herefore will illustrate ASI’s contribution on this application domain\, alongside the current perspectives\, in light of the COSMO-SkyMed program me (upstream) and “Multi-mission and Multi-Frequency SAR” and I4DP pro grammes (downstream)\, the latter with particular focus on the initiative dedicated to scientific users (I4DP_SCIENCE).\n\nReferences\nTapete et al.
