Snow Height Classification Dataset

Snow Height Classification dataset provides manually annotated snow height data that can be used for development and evaluation of automatic snow height classification approaches.
A subset of 20 IMIS stations which span different locations and elevations and vary in underlying surface (e.g., vegetation, bare ground, glacier, etc.) were selected and manually annotated with binary two-class ground truth information regarding snow height data:
* **Class 0 - Snow** - the surface is covered by snow
* **Class 1 - No Snow** - the surface is snow-free (e.g., vegetation, soil, rocks, etc.)
Data has been annotated with the help of domain experts. It should be mentioned that annotating historical data is problematic, as there is no way of checking whether there really was snow at the station or not. This means that assessing the presence of snow with the help of information from other sensors should be considered a best effort approach.
Besides the annotated snow height data, the dataset also contains additional data which are relevant to reproduce results in the following repository:

本雪高分类数据集（Snow Height Classification dataset）提供经人工标注的雪高数据，可用于自动雪高分类方法的开发与评估。
数据集构建时选取了覆盖不同区位与海拔、下垫面类型各异（如植被、裸地、冰川等）的20个IMIS监测站子集，并针对其雪高数据标注了二元二分类的地面真值标签：
* **类别0 - 有雪（Class 0 - Snow）**：地表被积雪覆盖
* **类别1 - 无雪（Class 1 - No Snow）**：地表无积雪（如植被、土壤、岩石等）
本数据集由领域专家协助完成标注。需说明的是，对历史数据进行标注存在局限性：无法核实该监测站现场当时是否确实存在积雪。因此，借助其他传感器信息推断积雪存在性仅能视作尽力而为的近似方案。
除经人工标注的雪高数据外，本数据集还包含可复现下述代码仓库中实验结果的补充数据：
