Standard Area Measurements for the Local Authority Districts (December 2024) in the UK

This CSV file contains the Standard Area Measurements (SAM) for the local authority districts 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文件包含截至2024年12月31日英国地方当局辖区的标准面积测量值（Standard Area Measurements, SAM）。所有测量值均为平面面积，未考虑地形起伏（如山地、山谷）带来的差异。测量单位为公顷（10000平方米），保留两位小数。本次数据集共包含四类测量值：总幅员面积（AREAEHECT）、平均高潮线以上区域（含海岸线）（AREACHECT）、内陆水域面积（AREAIHECT），以及扣除内陆水域后的平均高潮线以上区域（即陆地面积）（AREALHECT）。
