Sahel Land Cover OSO 2018

A land cover map of the Sahel region for the reference year 2018 produced by supervised classification of Sentinel-2 image time series and using the CGLS maps as reference data for supervision. The nomenclature is the following: tree cover:10<br> forest:100<br> evergreen needleleaf closed forest:111<br> evergreen broadleaf closed forest:112<br> deciduous needleleaf closed forest:113<br> deciduous broadleaf closed forest:114<br> closed forest mixed:115<br> closed forest unknown type:116<br> evergreen needleleaf open forest:121<br> evergreen broadleaf open forest:122<br> deciduous needleleaf open forest:123<br> deciduous broadleaf open forest:124<br> open forest mixed:125<br> open forest unknown type:126<br> shrubs:20<br> herbaceous vegetation:30<br> cropland:40<br> urban:50<br> bare / sparse vegetation:60<br> snow &amp; ice:70<br> permanent water bodies:80<br> temporary water bodies:81<br> herbaceous wetland:90<br> sea:200<br> continental land mass not classified:255 The map was produced using iota2, a free and open source platform for automatic map production using satellite image time series.本数据集为参考年2018年的萨赫勒（Sahel）地区土地覆盖图，通过对Sentinel-2影像时序开展监督分类制作而成，并以CGLS地图作为监督分类的参考数据。本次数据集采用的分类命名规则如下： - 林木覆盖：10 - 森林：100 - 常绿针叶封闭林：111 - 常绿阔叶封闭林：112 - 落叶针叶封闭林：113 - 落叶阔叶封闭林：114 - 混合封闭林：115 - 类型不明封闭林：116 - 常绿针叶开阔林：121 - 常绿阔叶开阔林：122 - 落叶针叶开阔林：123 - 落叶阔叶开阔林：124 - 混合开阔林：125 - 类型不明开阔林：126 - 灌丛：20 - 草本植被：30 - 耕地：40 - 城市用地：50 - 裸地/稀疏植被：60 - 冰雪：70 - 永久性水体：80 - 临时性水体：81 - 草本湿地：90 - 海洋：200 - 未分类大陆陆地：255 该土地覆盖图依托iota2平台制作完成，iota2是一款基于卫星影像时序实现自动制图的免费开源平台。
