New challenges have emerged in terms of data interoperability, sharing, and trustworthiness due to the rapidly increasing volume of heterogeneous data generated by multiple technologies. Hence, there is a need for efficient harmonization and smart modeling of the data to foster advanced AI analytical processes, which will lead to efficient water data management. The main objective of this work is to propose two Smart Data Models focusing on the modeling of the satellite imagery data and the flood risk assessment processes. The utilization of those models reinforces the fusion and homogenization of diverse information and data, facilitating the adoption of AI technologies for flood mapping and monitoring. Furthermore, a holistic framework is developed and evaluated via qualitative and quantitative performance indicators revealing the efficacy of the proposed models concerning the usage of the models in real cases. The framework is based on the well-known and compatible technologies on NGSI-LD standards which are customized and applicable easily to support the water data management processes effectively.<\/jats:p>","DOI":"10.3390\/info15050257","type":"journal-article","created":{"date-parts":[[2024,5,2]],"date-time":"2024-05-02T07:04:14Z","timestamp":1714633454000},"page":"257","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["FIWARE-Compatible Smart Data Models for Satellite Imagery and Flood Risk Assessment to Enhance Data Management"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1404-0500","authenticated-orcid":false,"given":"Ioannis-Omiros","family":"Kouloglou","sequence":"first","affiliation":[{"name":"Information Technologies Institute (ITI)\u2014Centre for Research and Technology Hellas (CERTH), 57001 Thermi-Thessaloniki, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7424-8928","authenticated-orcid":false,"given":"Gerasimos","family":"Antzoulatos","sequence":"additional","affiliation":[{"name":"Information Technologies Institute (ITI)\u2014Centre for Research and Technology Hellas (CERTH), 57001 Thermi-Thessaloniki, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2029-8409","authenticated-orcid":false,"given":"Georgios","family":"Vosinakis","sequence":"additional","affiliation":[{"name":"Institute of Communication and Computer Systems (ICCS), 15773 Zografou, Greece"}]},{"given":"Francesca","family":"Lombardo","sequence":"additional","affiliation":[{"name":"Eastern Alps River Basin District Authority (AAWA), Cannaregio 4314, 30121 Venice, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0243-4606","authenticated-orcid":false,"given":"Alberto","family":"Abella","sequence":"additional","affiliation":[{"name":"FIWARE Foundation, Franklinstrasse 13, 10587 Berlin, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5430-0840","authenticated-orcid":false,"given":"Marios","family":"Bakratsas","sequence":"additional","affiliation":[{"name":"Information Technologies Institute (ITI)\u2014Centre for Research and Technology Hellas (CERTH), 57001 Thermi-Thessaloniki, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7615-8400","authenticated-orcid":false,"given":"Anastasia","family":"Moumtzidou","sequence":"additional","affiliation":[{"name":"Information Technologies Institute (ITI)\u2014Centre for Research and Technology Hellas (CERTH), 57001 Thermi-Thessaloniki, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3761-3631","authenticated-orcid":false,"given":"Evangelos","family":"Maltezos","sequence":"additional","affiliation":[{"name":"Institute of Communication and Computer Systems (ICCS), 15773 Zografou, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5234-9795","authenticated-orcid":false,"given":"Ilias","family":"Gialampoukidis","sequence":"additional","affiliation":[{"name":"Information Technologies Institute (ITI)\u2014Centre for Research and Technology Hellas (CERTH), 57001 Thermi-Thessaloniki, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5078-3248","authenticated-orcid":false,"given":"Eleftherios","family":"Ouzounoglou","sequence":"additional","affiliation":[{"name":"Institute of Communication and Computer Systems (ICCS), 15773 Zografou, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2505-9178","authenticated-orcid":false,"given":"Stefanos","family":"Vrochidis","sequence":"additional","affiliation":[{"name":"Information Technologies Institute (ITI)\u2014Centre for Research and Technology Hellas (CERTH), 57001 Thermi-Thessaloniki, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4089-1990","authenticated-orcid":false,"given":"Angelos","family":"Amditis","sequence":"additional","affiliation":[{"name":"Institute of Communication and Computer Systems (ICCS), 15773 Zografou, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6447-9020","authenticated-orcid":false,"given":"Ioannis","family":"Kompatsiaris","sequence":"additional","affiliation":[{"name":"Information Technologies Institute (ITI)\u2014Centre for Research and Technology Hellas (CERTH), 57001 Thermi-Thessaloniki, Greece"}]},{"given":"Michele","family":"Ferri","sequence":"additional","affiliation":[{"name":"Eastern Alps River Basin District Authority (AAWA), Cannaregio 4314, 30121 Venice, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4698","DOI":"10.1021\/acs.est.9b04251","article-title":"The Fourth-Revolution in the Water Sector Encounters the Digital Revolution","volume":"54","author":"Corominas","year":"2020","journal-title":"Environ.
