Import geemap library¶

The geemap Python package has two plotting backends: ipyleaflet and folium. A key difference between folium and ipyleaflet is that ipyleaflet is built upon ipywidgets and allows bidirectional communication between the front-end and the backend enabling the use of the map to capture user input, while folium is meant for displaying static data only (source). Note that Google Colab currently does not support ipyleaflet (source). Therefore, if you are using geemap with Google Colab, geemap will automatically use the folium plotting backend.

Add Earth Engine data¶

# Add Earth Engine dataset
image = ee.Image("USGS/SRTMGL1_003")

# Set visualization parameters.
vis_params = {
    "min": 0,
    "max": 4000,
    "palette": ["006633", "E5FFCC", "662A00", "D8D8D8", "F5F5F5"],
}

# Print the elevation of Mount Everest.
xy = ee.Geometry.Point([86.9250, 27.9881])
elev = image.sample(xy, 30).first().get("elevation").getInfo()
print("Mount Everest elevation (m):", elev)

# Add Earth Engine layers to Map
Map.addLayer(image, vis_params, "DEM")
Map.addLayer(xy, {"color": "red"}, "Mount Everest")

# Center the map based on an Earth Engine object or coordinates (longitude, latitude)
# Map.centerObject(xy, 4)
Map.setCenter(86.9250, 27.9881, 4)

# Add Earth Engine dataset image = ee.Image("USGS/SRTMGL1_003") # Set visualization parameters. vis_params = { "min": 0, "max": 4000, "palette": ["006633", "E5FFCC", "662A00", "D8D8D8", "F5F5F5"], } # Print the elevation of Mount Everest. xy = ee.Geometry.Point([86.9250, 27.9881]) elev = image.sample(xy, 30).first().get("elevation").getInfo() print("Mount Everest elevation (m):", elev) # Add Earth Engine layers to Map Map.addLayer(image, vis_params, "DEM") Map.addLayer(xy, {"color": "red"}, "Mount Everest") # Center the map based on an Earth Engine object or coordinates (longitude, latitude) # Map.centerObject(xy, 4) Map.setCenter(86.9250, 27.9881, 4)
