Abstract
In the context of Kazakhstan’s ongoing digital transformation, the development of geo-portals based on geospatial databases has become a strategic direction for improving the efficiency and transparency of spatial data management. The purpose of this study is to evaluate the effectiveness of using geographical databases in the design and implementation of geo-portals and to propose methodological approaches for building a unified geoinformation environment in the country. The research employed platforms such as QGIS, ArcGIS Pro, PostgreSQL/PostGIS, and Leaflet, enabling the integration and visualization of administrative, hydrographic, agricultural, and infrastructural data layers. Emphasis was placed on adherence to open standards (e.g., OGC WMS/WFS, ISO-compliant metadata), role-based access control, and scalable deployment patterns suitable for multi-departmental use. The proposed geo-portal architecture combines data processing, analysis, and visualization workflows, provides near real-time access to spatial information, and incorporates data-quality assurance (topology checks, schema validation), caching, and logging for performance and auditability. Evaluation included interoperability testing with regional and national GIS systems, response-time benchmarking under load, and user acceptance testing with domain experts. The results demonstrate that the application of geodatabases significantly enhances interoperability across platforms, improves discoverability and reuse of authoritative datasets, and contributes to the digital transformation of land management, environmental monitoring, and spatial planning processes in Kazakhstan. The study concludes with practical recommendations on governance, data lifecycle management, and technology stack selection to support sustainable, secure, and extensible geo-portal implementations.
