Install packages¶

Uncomment the following code blocks to install GDAL, leafmap, and localtileserver on SageMaker Studio Lab.

In [1]:

# %pip install --find-links=https://girder.github.io/large_image_wheels --no-cache GDAL

# %pip install --find-links=https://girder.github.io/large_image_wheels --no-cache GDAL

In [2]:

# pip install leafmap localtileserver matplotlib==3.6.3 folium==0.13.0

# pip install leafmap localtileserver matplotlib==3.6.3 folium==0.13.0

Restart the kernel after installing the packages.

Import libraries¶

ipyleaflet currently does not work on SageMAker Studio Lab. See this issue. We can use the folium plotting backend instead.

import leafmap.foliumap as leafmap

Visualize local raster data¶

Download a sample raster dataset.

In [4]:

url = 'https://open.gishub.org/data/raster/srtm90.tif'
leafmap.download_file(url, 'dem.tif')

url = 'https://open.gishub.org/data/raster/srtm90.tif' leafmap.download_file(url, 'dem.tif')

dem.tif already exists. Skip downloading. Set overwrite=True to overwrite.

Create an interactive map.

In [5]:

m = leafmap.Map()
m.add_raster('dem.tif', palette='terrain', layer_name='Local Raster')
m

m = leafmap.Map() m.add_raster('dem.tif', palette='terrain', layer_name='Local Raster') m

Out[5]:

Create a split-view map.

In [6]:

m = leafmap.Map()
m.split_map(
    left_layer='dem.tif', right_layer='dem.tif', right_args={'palette': 'terrain'}
)
m

m = leafmap.Map() m.split_map( left_layer='dem.tif', right_layer='dem.tif', right_args={'palette': 'terrain'} ) m
