We need a function for constructing equidistant points (buffer)

from given geometry (point, line, polygon). All attempts to build

and draw a circle around a point do not give correct coordinates

(ellipse comes out) and smaller area.

from [login to view URL] import models

from [login to view URL] import Point, Polygon

p = [login to view URL](50.41585888372478, 30.606115208485846, srid=4326)

width = 1000

buff_width = width * 360 / 40075000

buff = [login to view URL](1000, quadsegs=20)

print(f'[login to view URL]: {[login to view URL](width*width)}

1. drawing gives an ellipse stretched along the meridian

2. [login to view URL] is not equal to 3.14 km2 (counts less)

Transformations to projections other than 4326, and back

translation to srid = 4326 give an ellipse when drawing...
