National mapping of pals ants in Sweden

The dataset is a total mapping of Sweden’s pals ants reported in the form of a 100x100m grid with the presence of palas and palas-related water. Pales and pals-related water are shown in % for respectively 100x100 m’s square. For definitions see reference document. The data described have the attributes: Pales = percentage of pals 0-100 %, PALS_VATT = proportion of palis-related water 0-100 %. PALS_HA = area pals in hectares, PALSVATTHA = area of pals-related water in hectares. Minor errors in the shape files were corrected 2017-03-17.本数据集为瑞典冰核丘区域的全域测绘成果，以100米×100米网格形式呈现，记录了各网格单元内冰核丘及冰核丘相关水域的分布情况。各100米×100米网格单元内，冰核丘占比与冰核丘相关水域占比均以百分比形式标注。 相关定义详见参考文档。 本次描述的数据包含以下属性：Pales（冰核丘占比，取值范围0-100%）、PALS_VATT（冰核丘相关水域占比，取值范围0-100%）、PALS_HA（冰核丘面积，单位：公顷）、PALSVATTHA（冰核丘相关水域面积，单位：公顷）。 本数据集的矢量形状文件（shape files）存在少量误差，已于2017年3月17日完成修正。
