SWECO25: Geologic (geol)

The geologic category contains the "geotechnic" dataset.

The geotechnic dataset describes the subsoil of Switzerland. After rasterizing and resampling the source data (Swisstopo, 1967) to the SWECO25 grid, we generated individual layers for the 30 classes that were available. For each class, we provided the binary maps (0 or 1) and computed 13 focal statistics layers by applying a cell-level function calculating the average percentage cover value for a given class in a circular moving window of 13 radii ranging from 25m to 5km. This dataset includes a total of 420 layers. Final values were rounded and multiplied by 100.

The detailed list of layers available is provided in SWECO25_datalayers_details_geol.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.

地质类别包含“岩土工程（geotechnic）”数据集。

该岩土工程数据集描述了瑞士的地下土层。我们将源数据（瑞士联邦地形局（Swisstopo），1967年）栅格化并重采样至SWECO25网格后，为30个可用分类生成了独立图层。针对每个分类，我们提供了二值映射图（取值为0或1），并通过像元级函数，对半径介于25米至5千米的13个圆形移动窗口，计算给定分类的平均覆盖百分比，由此生成13个邻域统计（focal statistics）图层。该数据集总计包含420个图层。最终数值经取整后乘以100。

可用图层的详细列表已在SWECO25_datalayers_details_geol.csv中提供，其中涵盖类别、数据集、长变量名、短变量名、时段、子时段、起始年份、结束年份、属性、半径、单位及文件路径等信息。
