Standard Area Measurements for the Parishes and Non-Civil Parished Areas (December 2022) in EW

This CSV file contains the Standard Area Measurements (SAM) for the parishes and non-civil parished areas in England and Wales as at December 2022. 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2022年12月的英格兰及威尔士境内民政教区与非民政教区区域的标准面积测量值（Standard Area Measurements，SAM）。所有测量值均为平面投影面积，未计入山地、山谷等地形起伏带来的影响。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项：总范围面积（AREAEHECT）、平均高潮线（海岸线）范围面积（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面积（陆地面积，AREALHECT）。
