description: This dataset, published by the Swiss Confederation through the Federal Office of Topography (swisstopo), maps production and mining sites of the hard rock aggregates industry in Switzerland. Hard rock aggregates are essential raw materials for building and maintaining infrastructure, particularly railway ballast for the Swiss rail network and materials used in high-performance road construction. The data identifies the location of extraction and processing sites nationwide, supporting infrastructure planning and resource management. Further background information is available at www.mat-min.ch. The dataset is provided as a national, freely accessible resource without authentication requirements, relevant to transport infrastructure and construction material supply.
