quadrantic

Determination of quadrants based on angle, coordinates and others

Overview

This library allows you to determine quadrant(s) based on

• angle (360° or 400 Gon)
• location (latlon)

Setup

Via Pip:

pip install quadrantic

Via Github (latest):

pip install git+https://github.com/earthobservations/quadrantic

Implementations

Get quadrant for angle
