InSAR-based services now cover entire countries and soon even the whole of Europe. These InSAR systems require massive amounts of computer processing power and significant time to generate a final product. Most, if not all, of these projects have a limited \u201cmonitoring component\u201d, aimed at historical analysis but are rarely, if ever, updated. Consequently, the results do not necessarily meet every purpose or specific user requirement. It is now clear that the increasing computing capacity and big data provided by the sensors have initiated the development of new InSAR services. However, these systems are only useful when linked to specific real-world operational problems. Continuous monitoring of a country\u2019s ageing water management infrastructure has become an increasingly critical issue in recent years, in addition to the threats posed by climate change. Our article provides a comprehensive overview of a nationwide, dedicated, operational InSAR application, which was developed to support the operational work of the Hungarian Disaster Management Service (HDMS). The objective was to provide monthly monitoring of 63 water facilities, including 83 individual objects, distributed throughout Hungary, in combination with the development of a near real-time warning system. Our work involved the compilation of a completely new InSAR System as a Service (SaaS) which incorporates user requirements, preparatory work, the compilation of the Sentinel-1 automatic processing pipeline, the installation of corner reflectors, a special early warning system, and a dedicated user interface. The developed system can automatically start to evaluate the S1 measurements within 24 h of downloading the data into the system storage forward the results toward the warning system before the next image arrives. Users are provided with detailed information on the stability of 70% of the 83 water facility objects monitored through the dedicated user interface. The additional early warning system currently operates as a preliminary \u201cspatial decision support system\u201d, but the HDMS is willing to make it fully operational over the next few years.<\/jats:p>","DOI":"10.3390\/rs14143251","type":"journal-article","created":{"date-parts":[[2022,7,6]],"date-time":"2022-07-06T21:15:52Z","timestamp":1657142152000},"page":"3251","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Nationwide, Operational Sentinel-1 Based InSAR Monitoring System in the Cloud for Strategic Water Facilities in Hungary"],"prefix":"10.3390","volume":"14","author":[{"given":"Levente","family":"Ronczyk","sequence":"first","affiliation":[{"name":"Department of Cartography and GIS, Institute of Geography and Earth Sciences, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e1s","family":"Zelenka-Hegyi","sequence":"additional","affiliation":[{"name":"Independent Researcher, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00e1bor","family":"T\u00f6r\u00f6k","sequence":"additional","affiliation":[{"name":"Independent Researcher, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9721-6216","authenticated-orcid":false,"given":"Zolt\u00e1n","family":"Orb\u00e1n","sequence":"additional","affiliation":[{"name":"Structural Diagnostics and Analysis Research Group, Faculty of Engineering and Information Technology, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Defilippi","sequence":"additional","affiliation":[{"name":"Sarmap S.A., 6987 Caslano, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0270-4365","authenticated-orcid":false,"given":"Istv\u00e1n P\u00e9ter","family":"Kov\u00e1cs","sequence":"additional","affiliation":[{"name":"Department of Cartography and GIS, Institute of Geography and Earth Sciences, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5403-6410","authenticated-orcid":false,"given":"D\u00e1niel M\u00e1rton","family":"Kov\u00e1cs","sequence":"additional","affiliation":[{"name":"Doctoral School of Earth Sciences, University of P\u00e9cs, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P\u00e9ter","family":"Burai","sequence":"additional","affiliation":[{"name":"Remote Sensing Centre, University of Debrecen, 4032 Debrecen, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Pasquali","sequence":"additional","affiliation":[{"name":"Sarmap S.A., 6987 Caslano, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Crosetto, M., Solari, L., Mr\u00f3z, M., Balasis-Levinsen, J., Casagli, N., Frei, M., Oyen, A., Moldestad, D.A., Bateson, L., and Guerrieri, L.
