geobuffers - a minipackage for computing areas around points

Geobuffers

This repository contains code that allows simple definitions of polygons defined around a coordinate of interest using geodesic distances. Some of the functionality can be reproduced with geopandas buffer functionality.

Instead, all methods here rely on pyproj.Geod geodetic computations using Clarke 1866 Ellipsoid.

Available shapes

	Name	Parameters	Description
	square	radius, azimuth_angle	Square with a distance center-to-corner radius and rotated by azimuth_angle
	triangle	radius, azimuth_angle	Square with a distance center-to-corner radius and rotated by azimuth_angle
	hexagon	radius, azimuth_angle	Hexagon with a distance center-to-vertex radius and rotated by azimuth_angle
	regpol	n, radius, azimuth_angle	Regular polygon with n vertices radius metres away from the center, with first vertex at azimuth of azimuth_angle degrees
	fov	radius, azimuth_angle, fov_angle	Field of view traingle at distance radius, pointing towards angle azimuth_angle with angular width of fov_angle degrees

Example Usage

  import geobuffers as gbf
  from shapely import Point

  my_point = Point([1.0, -1.0])

  square(my_point)
