Using pip to install is also possible.
pip install pydantic_geojson

GEOJSON
GeoJSON is a format for encoding a variety of geographic data structures.
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [125.6, 10.1]
},
"properties": {
"name": "Dinagat Islands"
}
}

GeoJSON supports the following geometry types: Point, LineString, Polygon,
MultiPoint, MultiLineString, and MultiPolygon. Geometric objects with
additional properties are Feature objects. Sets of features are contained by
FeatureCollection objects.
Examples of using
Custom properties:
from pydantic import BaseModel
from pydantic_geojson import FeatureModel


class MyPropertiesModel(BaseModel):
name: str


class MyFeatureModel(FeatureModel):
properties: MyPropertiesModel


data = {
"type": "Feature",
"properties": {
"name": "foo name",
},
"geometry": {
"type": "Polygon",
"coordinates": [
[
[-80.724878, 35.265454],
[-80.722646, 35.260338]
]
]
}
