Download a sample DEM dataset.

In [ ]:

out_dir = os.getcwd()
dem = os.path.join(out_dir, "dem.tif")
dem_url = (
    "https://drive.google.com/file/d/1vRkAWQYsLWCi6vcTMk8vLxoXMFbdMFn8/view?usp=sharing"
)
leafmap.download_file(dem_url, "dem.tif", unzip=False)

out_dir = os.getcwd() dem = os.path.join(out_dir, "dem.tif") dem_url = ( "https://drive.google.com/file/d/1vRkAWQYsLWCi6vcTMk8vLxoXMFbdMFn8/view?usp=sharing" ) leafmap.download_file(dem_url, "dem.tif", unzip=False)

Create an interactive map.

In [ ]:

Map = leafmap.Map()
Map

Map = leafmap.Map() Map

Use the built-in toolbox to perform geospatial analysis. For example, you can perform depression filling using the sample DEM dataset downloaded in the above step.

Display the toolbox using the default mode.

In [ ]:

leafmap.whiteboxgui()

leafmap.whiteboxgui()

Display the toolbox using the collapsible tree mode. Note that the tree mode does not support Google Colab.

In [ ]:

leafmap.whiteboxgui(tree=True)

leafmap.whiteboxgui(tree=True)
