error in loading local tif files: Map.add_raster(filename, band=[4, 1, 2], layer_name="Color infrared")

[wondering516]

it happens in tutorial notebooks

url = 'https://github.com/giswqs/data/raw/main/raster/srtm90.tif'
filename = 'dem.tif'
geemap.download_file(url, filename)
Map = geemap.Map()
Map.add_raster(filename, cmap='terrain', layer_name="DEM")
vis_params = {'min': 0, 'max': 4000, 'palette': 'terrain'}
Map.add_colorbar(vis_params, label='Elevation (m)')
Map

the error is

This is localtileserver issue. Please try the following code with your own data. If it does not work, please open an issue on the localtileserver repo.

from localtileserver import TileClient, get_leaflet_tile_layer, examples
from ipyleaflet import Map

# Create a TileClient from a raster file
# client = TileClient('path/to/geo.tif')
client = examples.get_san_francisco()  # use example data

# Create ipyleaflet TileLayer from that server
t = get_leaflet_tile_layer(client)
# Create ipyleaflet map, add tile layer, and display
m = Map(center=client.center(), zoom=client.default_zoom)
m.add(t)
m

I solve the problem by changing Proxy Software mode, from global mode to rule mode.

[wondering516]

but i have another problem, add multi tif files(from different part) into the map, these tif files will stack together in the first tif area.

Map = geemap.Map()
Map.add_raster("/ImperviousDataset/label/Shenzhen_0.tif", vmin=0, vmax=1, layer_name="label1")
Map.add_raster("/ImperviousDataset/label/Shenzhen_1.tif", vmin=0, vmax=1, layer_name="label2")
Map.add_raster("/ImperviousDataset/label/Shenzhen_2.tif", vmin=0, vmax=1, layer_name="label3")
Map.add_raster("/ImperviousDataset/label/Shenzhen_3.tif", vmin=0, vmax=1, layer_name="label4")
Map.add_raster("/ImperviousDataset/label/Shenzhen_4.tif", vmin=0, vmax=1, layer_name="label5")
Map

all five tif files show in the same area, stack together
