raster_path = geoai.download_file(raster_url)

In [ ]:

vector_path = geoai.download_file(vector_url)

vector_path = geoai.download_file(vector_url)

Preview data¶

In [ ]:

geoai.view_image(raster_path, figsize=(18, 10))

geoai.view_image(raster_path, figsize=(18, 10))

In [ ]:

geoai.view_vector(vector_path, basemap=True, alpha=0.5, figsize=(18, 10))

Convert vector to raster¶

In [ ]:

output_path = vector_path.replace(".geojson", ".tif")
geoai.vector_to_raster(vector_path, output_path, reference_raster=raster_path)

output_path = vector_path.replace(".geojson", ".tif") geoai.vector_to_raster(vector_path, output_path, reference_raster=raster_path)

In [ ]:

geoai.view_image(output_path, figsize=(18, 10))

geoai.view_image(output_path, figsize=(18, 10))

Generate image chips¶

In [ ]:

tiles = geoai.export_geotiff_tiles(
    in_raster=raster_path,
    out_folder="output",
    in_class_data=vector_path,
    tile_size=512,
    stride=256,
    buffer_radius=0,
    create_overview=True,
)

tiles = geoai.export_geotiff_tiles( in_raster=raster_path, out_folder="output", in_class_data=vector_path, tile_size=512, stride=256, buffer_radius=0, create_overview=True, )
