Drying plants

A drying plant is a dry-ground former lake or more. The polders in the drying houses have a straight lined plot and are usually a few meters lower than the surrounding area. The dataset ‘Droogmakerijen’ contains a national mapping of drying plants as defined as type in the NAi Polderatlas. These drying plants are divided according to the period of origin and have data fields for current polder level and year of drying. This dataset includes the Mills and Gemalen dataset, which shows the grinding device(s) for drying at the relevant drying plant.干燥场（drying plant）指曾为湖泊或更大水域的干涸土地。该干燥场范围内的圩田地块呈规整直线状，通常较周边区域低数米。 数据集"Droogmakerijen"包含依据《NAi圩田图集（NAi Polderatlas）》中定义的干燥场类型的全国性测绘数据。该类干燥场按其起源时期进行分类，并包含当前圩田高程与干燥年份两类数据字段。 本数据集涵盖"磨坊与盖马伦数据集（Mills and Gemalen dataset），该数据集记录了对应干燥场配套的干燥作业所用的粉碎装置。
