multiple legend

[5luca]

Hi,

could you please tell me if is it possible to display two legends at the same time? I try to visualize two or more layers in the map and I would like to display a legend of the layers as well.

Thank you for your advice!

Update the package using geemap.update_package() and follow the example below to add multiple legends. The limitation is that the legends might not have equal width.

import ee
import geemap

Map = geemap.Map()

# Add first legend
legend_dict = {
    '11 Open Water': '466b9f',
    '12 Perennial Ice/Snow': 'd1def8',
    '21 Developed, Open Space': 'dec5c5',
    '22 Developed, Low Intensity': 'd99282',
    '23 Developed, Medium Intensity': 'eb0000',
    '24 Developed High Intensity': 'ab0000',
    '31 Barren Land (Rock/Sand/Clay)': 'b3ac9f',
    '41 Deciduous Forest': '68ab5f',
    '42 Evergreen Forest': '1c5f2c',
    '43 Mixed Forest': 'b5c58f',
    '51 Dwarf Scrub': 'af963c',
    '52 Shrub/Scrub': 'ccb879',
    '71 Grassland/Herbaceous': 'dfdfc2',
    '72 Sedge/Herbaceous': 'd1d182',
    '73 Lichens': 'a3cc51',
    '74 Moss': '82ba9e',
    '81 Pasture/Hay': 'dcd939',
    '82 Cultivated Crops': 'ab6c28',
    '90 Woody Wetlands': 'b8d9eb',
    '95 Emergent Herbaceous Wetlands': '6c9fb8'
}

landcover = ee.Image('USGS/NLCD/NLCD2016').select('landcover')
Map.addLayer(landcover, {}, 'NLCD Land Cover')
Map.add_legend(legend_title="NLCD Land Cover", legend_dict=legend_dict, layer_name='NLCD Land Cover')

# Add second legend
water = ee.Image('JRC/GSW1_2/GlobalSurfaceWater').select("max_extent").selfMask()
Map.addLayer(water, {'palette': 'blue'}, "JRC Water")
Map.add_legend(legend_title="Legend", legend_dict={"Global Surface Water": "0000ff"}, layer_name='JRC Water')
