Geodesic Point Buffer

Example

Here it’s a example of use of point bufferization with 500 meters of radius. After bufferization is saved the result in a file.

from moredata.utils.util import geodesic_point_buffer

import json

DATASETS_DIR = "../datasets/"
USER_DATA = DATASETS_DIR + "user_profile_17092019_preprocessed.json"

USER_PROJECT_DATA = "./data/amenity-restaurant-0.json"

with open(USER_PROJECT_DATA) as f:
    data = json.loads(f.read())
    counter = 0
    for d in data:
        for points in d["points_of_interest"]:
            shp = Polygon(geodesic_point_buffer(points["latitude"], points["longitude"], 500))
            points["area_point"] = shp.wkt
    with open("./data/amenity-restaurant-0.json", 'w') as outfile:
        json.dump(data, outfile, ensure_ascii=False)
