一、问题描述：

GEE中，如何对土地利用类型进行重新分类（ArcMap中为reclassify，GEE中为remap）？

本次进行分析的区域为北运河流域，北运河位于海河流域，是流经北京、河北和天津3个区域的跨区域河流，北运河发源于北京市昌平县燕山南麓,西界永定河,东临潮白河,先后流经北京市通州区、河北省廊坊市香河县和天津市武清区、北辰区和红桥区。通州区北关闸以上称温榆河，北关闸以下始称北运河，沿途纳通惠河、凉水河、凤港减河等平原河道，于屈家店与永定河交汇，至子北汇合口入海河，干流长143公里。流域面积6166 平方公里。

二、获取影像集并显示：

1、分析步骤

分析步骤如下所示：

加载分析区域

加载区域土地覆盖数据

未合并类型的区域土地利用情况

对比分析

2、加载分析的流域

python代码如下：

byh = r'C:\Users\TTT\geemap-master\examples\world_basins\byh.shp'
roi = geemap.shp_to_ee(byh)
Map = geemap.Map()
# 添加显示
Map.centerObject(roi)
roi_outline = ee.Image().paint(roi, 0, 2)
Map.addLayer(roi_outline, {'palette':'red'}, 'roi')
Map

结果显示如下：

三、加载区域土地覆盖数据并添加图例

需要掌握geemap.add_legend()函数

geemap.add_legend()
数据简介

欧洲航天局（ESA）< ESA WorldCover 10 m 2020 > 产品基于Sentinel-1和Sentinel-2数据提供了一种新的全球地表覆盖产品，分辨率为10米，时间为2020年。

该产品是在欧空局世界覆盖项目 < ESA WorldCover project >的框架内生成的，该项目是欧洲航天局第五个地球观测包络线计划（EOEP-5）的一部分。

该产品包括11个地表覆盖类别：分别为林地，灌木，草地，耕地，建筑，裸地/稀疏植被区，雪和冰，开阔水域，草本湿地，红树林，苔藓。
表 0 < ESA WorldCover 10 m 2020 > 数据简介
值色彩映射地表覆盖类型
10 #006400 林地
20 #ffbb22 灌木
30 #ffff4c 草地
40 #f096ff 耕地
50 #fa0000 建筑
60 #b4b4b4 裸地/稀疏植被区
70 #f0f0f0 雪和冰
80 #0064c8 开阔水域
90 #0096a0 草本湿地
95 #00cf75 红树林
100 #fae6a0 苔藓
————————————————

# 加载土地覆盖数据，剪裁分析区域
esa_landcover_roi = ee.ImageCollection('ESA/WorldCover/v100') \.first() \.clip(roi)
Map.addLayer(esa_landcover_roi, {}, 'landcover')
# 添加图例
legend_dict_cn = {'林地': '006400','灌木': 'ffbb22','草地':'ffff4c','耕地':'f096ff','建设用地':'fa0000','裸地/稀疏植被区':'b4b4b4','雪和冰':'f0f0f0','水体':'0064c8','沼泽':'0096a0','红树林':'00cf75','苔藓':'fae6a0'
}
Map.add_legend(legend_title='Land Cover Classification', legend_dict=legend_dict_cn)
Map

结果显示如下：

四、重分类

对土地利用类型进行重新分类处理，为展示该方法，将原类型中的水体、沼泽、红树林3类合并为水域一个类型，对应的代码合并情况为80、90、95，合并的类型，水域，代码设置为00。

学习remap()函数：

ee.Image.remap

五、学习小结：

学习了土地利用类型的重分类方法
学习添加图例的方法
