Converting DataFrames to GeoJSON

INPUT

from pandas_geojson import GeoJSON
import pandas as pd
gjson = GeoJSON()
data = pd.read_csv('Test.csv')
print(data.head())

OUTPUT

     name        lat        long marker-symbol marker-color
0  Random  48.702076 -111.855280          star      #C91313
1  Random  46.768477 -111.903907          star      #C91313
2  Random  49.768477 -112.903907          star      #C91313
3  Random  45.768477 -110.903907          star      #C91313

INPUT

geo_json = gjson.to_geojson(df=data, lat='lat', lon='long',
                 properties=['name','marker-symbol','marker-color'])
print(geo_json)

OUTPUT

{'type': 'FeatureCollection', 'features': [{'type': 'Feature', 'properties': {'name': 'Random', 'marker-symbol': 'star', 'marker-color': '#C91313'}, 'geometry': {'type': 'Point', 'coordinates': [-111.85528049999999, 48.70207631]}}, {'type': 'Feature', 'properties': {'name': 'Random', 'marker-symbol': 'star', 'marker-color': '#C91313'}, 'geometry': {'type': 'Point', 'coordinates': [-111.90390740000001, 46.768476899999996]}}, {'type': 'Feature', 'properties': {'name': 'Random', 'marker-symbol': 'star', 'marker-color': '#C91313'}, 'geometry': {'type': 'Point', 'coordinates': [-112.90390740000001, 49.768476899999996]}}, {'type': 'Feature', 'properties': {'name': 'Random', 'marker-symbol': 'star', 'marker-color': '#C91313'}, 'geometry': {'type': 'Point', 'coordinates': [-110.90390740000001, 45.768476899999996]}}]}

Opening GeoJSON

geo_json = gjson.read_geojson_url('https://raw.githubusercontent.com/plotly/datasets/master/geojson-counties-fips.json')

OR

geo_json = gjson.read_geojson('FIPS_Counties.geojson')

Saving GeoJSON

gjson.write_geojson(geo_json, 'Test.geojson')

Filtering GeoJSON

Sometimes you want to filter existing GeoJSON datasets to only include specific locations. This function accomplishes that.

import pandas as pd
from pands_geojson import GeoJSON
gjson = GeoJSON()
data = pd.read_csv('filter.csv')
lid_zips = data['FIPS'].astype(str).to_list()
counties = gjson.read_geojson('FIPS_Counties.geojson')
geo_json = gjson.filter_geojson(geo_json=counties, filter_list=lid_zips, property_key='GEO_ID')
print(geo_json)
