The Regional Bureau of Spatial Planning in Wroclaw is implementing a project to create a regional spatial data infrastructure (SDI) node for spatial planning in the Wroclaw functional area. The node will integrate multiple spatial data sources using web services to support spatial planning and management processes at the regional and local levels. It will be developed using open-source software and standards to be freely available to users and developers. The SDI node aims to facilitate monitoring, evaluation, and harmonization of spatial policy through publishing planning data and developing geospatial tools.
