SWECO25: Topographic (topo)

The topographic category contains the "alti3d" dataset.

The alti3D dataset (topographic category) describes the topography of Switzerland. After resampling the “SwissALTI3D” source data (swisstopo, 2016) to the SWECO25 grid with 4 resampling schemes (mean, median, minimum, and maximum value), we generated individual layers for four variables (elevation, aspect, hillshade, and slope). For each variable and resampling scheme, we computed 13 focal statistics layers by applying a cell-level function calculating the mean value in a circular moving window of 13 radii ranging from 25m to 5km. This dataset includes a total of 224 layers. Final values were rounded and multiplied by 100.

The detailed list of layers available is provided in SWECO25_datalayers_details_topo.csv and includes information on the category, dataset, variable name (long), variable name (short), period, sub-period, start year, end year, attribute, radii, unit, and path.
