South African Land Cover 2018 Class O Bare Resampled to a 1km Grid

Raster-based land cover dataset representing the full South African landscape for the full year 2018. Derived from 20m Sentinel 2 imagery acquired between 01 January 2018 and 31 December 2018. Land cover information classes based on new Gazetted land cover standards and legend content used in 2013-14 national land cover data. All land cover and land-use classes generated using automated modelling procedures for full operational repeatability and change detection. Class 25–31 of the 2018 South African National land cover dataset was clustered to derive South African land cover 2018 Class O Bare for the current product and resampled to a 1000 x 1000m grid resolution Albers Equal Area map projection +proj=aea +lat_1=-22 +lat_2=-38 +lat_0=-30 +lon_0=25 +x_0=1400000 +y_0=1300000 +datum=WGS84 +units=m +no_defs

本数据集为基于栅格的土地覆盖数据集，完整呈现2018年全年南非全境地表覆盖状况。其数据源自2018年1月1日至2018年12月31日期间获取的20米分辨率Sentinel 2（哨兵2号）遥感影像。土地覆盖信息分类体系采用2013-2014年全国土地覆盖数据所使用的最新经公报发布的土地覆盖标准及图例规范。所有土地覆盖与土地利用类别均通过自动化建模流程生成，以保障全流程可复现性与变化检测能力。本产品将2018年南非全国土地覆盖数据中的第25至31类进行聚类整合，得到2018年南非土地覆盖类别O：裸地，并将数据重采样至1000×1000米网格分辨率的阿尔伯斯等面积投影坐标系，投影参数为：+proj=aea +lat_1=-22 +lat_2=-38 +lat_0=-30 +lon_0=25 +x_0=1400000 +y_0=1300000 +datum=WGS84 +units=m +no_defs
