Slope direction in the mountainous — data from the lavin forecast service

The product is taken by classifying a subdata set of Lantmäteriets DEM 2 m (NH 2 +, rating level 3, which is based on laser scanned data) for use within the Swedish Environmental Protection Agency’s Lavin Forecasting Service. In the absence of a drawing, the Lantmäteriet DEM 50 m was used.本产品通过对瑞典国家土地测绘局（Lantmäteriet）的2米分辨率数字高程模型（Digital Elevation Model, DEM）子数据集（NH 2+，等级3，基于激光扫描数据构建）进行分类处理后生成，用于瑞典环境保护局的雪崩预报服务。当缺乏相关测绘图件时，则采用瑞典国家土地测绘局的50米分辨率数字高程模型。
