This study addresses that gap by developing and applying an integrative evaluation framework that combines four analytical dimensions: cartographic representation, interaction and engagement affordances, openness, and accessibility, while treating contextual characteristics as conditioning factors. The framework is operationalized through a mixed-methods content analysis of 26 publicly available geovisualizations based on open data. The results show that most cases are produced by public-sector actors, focus on environmental and transport themes, and rely on conventional cartographic techniques combined with medium levels of interactivity that support structured exploration rather than deeper analytical reasoning. Although many geovisualizations cite data sources and provide some form of data access, licensing remains inconsistent, particularly for the visualization artefacts themselves, limiting reuse potential. Accessibility is implemented even less consistently across geovisualizations, with recurring shortcomings in color contrast, keyboard navigation, screen-reader compatibility, and multilingual support. Overall, the findings suggest that the broader societal potential of geovisualizations based on open data may not be determined by individual features, but by balanced cross-dimensional configurations. Strengthening the integration of openness and accessibility alongside interaction and design may enhance the potential of geovisualizations to support reuse, inclusiveness, and public engagement.<\/jats:p>","DOI":"10.3390\/ijgi15060259","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T09:25:17Z","timestamp":1781083517000},"page":"259","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating Geovisualizations Based on Open Data: An Integrative Framework for Engagement, Openness, and Accessibility"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3324-201X","authenticated-orcid":false,"given":"Andrea","family":"Mileti\u0107","sequence":"first","affiliation":[{"name":"University of Zagreb Faculty of Geodesy, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1059-8395","authenticated-orcid":false,"given":"Ana Kuve\u017edi\u0107","family":"Divjak","sequence":"additional","affiliation":[{"name":"University of Zagreb Faculty of Geodesy, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Citizen engagement with open government data: Lessons learned from Indonesia\u2019s presidential election","volume":"14","author":"Purwanto","year":"2020","journal-title":"Transform.
