This CSV file contains the Standard Area Measurements (SAM) for the countries in the United Kingdom as at 31 December 2024. All measurements provided are ‘flat’ as they do not take into account variations in relief e.g. mountains and valleys. Measurements are given in hectares (10,000 square metres) to 2 decimal places. Four types of measurements are included: total extent (AREAEHECT), area to mean high water (coastline) (AREACHECT), area of inland water (AREAIHECT) and area to mean high water excluding area of inland water (land area) (AREALHECT).本CSV文件收录了截至2024年12月31日英国各构成国的标准面积测量值（Standard Area Measurements，SAM）。所有测量所得面积均为平面面积，未纳入山地、山谷等地形起伏的影响。测量单位为公顷（10000平方米），精确至小数点后两位。本次数据集共涵盖四类面积指标：总全域面积（AREAEHECT）、平均高潮线（海岸线）范围内面积（AREACHECT）、内陆水域面积（AREAIHECT），以及扣除内陆水域面积后的平均高潮线范围内面积（陆地面积，AREALHECT）。
