What's in the dataset

from pathlib import Path

DATA = Path('/srv/data/scshores-shorelines')

for f in sorted(DATA.rglob('*')):
    if f.is_file():
        print(f"{f.relative_to(DATA)}  ({f.stat().st_size/1e6:,.1f} MB)")

Load the data

The dataset is GeoJSON: data with geometry. GeoPandas loads and plots it in one line.

import geopandas as gpd

geo = sorted(DATA.rglob('*.geojson'))
print('Using:', geo[0].name)
df = gpd.read_file(geo[0])
print(df.shape)
df.plot(figsize=(9, 6))
df.head()
