The state of service-oriented technologies for the geovisualization of geospatial data in ukraine and trends in their development

<ns0:p>This article examines the current state of geospatial data visualization technologies and identifies the main trends in their development in the context of digitalization. It analyzes the architecture and functional capabilities of the national geoportal, as well as the network of geoportals operated by local governments and state administrations. The scientific novelty of the work lies in a systematic analysis of the implementation of service-oriented architecture (SOA) and Open Geospatial Consortium standards (WMS, WMTS, WFS, CSW) in domestic digital governance practices. A transition from static mapping to dynamic web-oriented GIS platforms has been identified. The research results, based on an analysis of real-world case studies of urban communities, demonstrate a high level of integration of visualization services (WMTS, WMS) despite a shortage of services providing direct access to objects (WFS, VectorTile). The conclusions drawn contribute to the optimization of spatial planning processes, territorial monitoring, and the making of informed management decisions in the context of the digital transformation of the state. The results of the study can be used to improve geoportals and develop geospatial data infrastructure.Received:27.03.2026;Accepted:04.05.2026;</ns0:p>
