natcap.invest.reports.vector_utils.get_geojson_bbox(geodataframe)

Get the bounding box of a GeoDataFrame as a GeoJSON feature.

Also calculate its aspect ratio. These are useful for cropping other layers in altair plots.

Parameters:

geodataframe (geopandas.GeoDataFrame)

Returns:

A 2-tuple containing:

• extent_feature (dict): A GeoJSON feature representing the bounding box of the input GeoDataFrame.

• xy_ratio (float): The aspect ratio of the bounding box (width/height).

Return type:

tuple
