The Spatial Data Infrastructure of the Federation of Bosnia and Herzegovina (IPP FBiH) has significantly advanced in recent years, leveraging open-source software (OSS) to enhance data sharing, visualization, and analysis. This paper presents the current state of IPP FBiH, emphasizing the availability of spatial datasets and the role of OSS in their distribution and management. Key initiatives have equipped and trained various institutions to utilize OSS solutions for spatial data infrastructure, including PostgreSQL/PostGIS for database management, GeoServer for web-based data sharing, QGIS for analysis, visualization, and editing, and HALE Studio for data transformation and migration.

Through targeted capacity-building efforts, training programs have been conducted for hundreds of public sector professionals, ensuring the effective adoption of OSS tools in daily workflows. These programs have focused on database management, spatial data publishing, geospatial analysis, and data interoperability. The paper also explores the benefits of OSS implementation, such as cost efficiency, technological independence, and enhanced collaboration between institutions. By examining real-world applications and success stories, this study highlights the transformative impact of OSS on IPP FBiH and provides recommendations for further strengthening the spatial data ecosystem through open solutions.
