Library for manipulating geographic things.
Class to represent a rectangular bounded space on the globe.
Calculate reasonable approximation of the midpoint of the bounds.
center : Point
Gets the grid of geocells that covers this Bounds object.
Gets the set of geocells that covers this Bounds object.
Class to represent a latitude, longitude pair.
Embeds radian values as member objects because most distance methods use radians rather than degrees. A copy of the approx_distance() function is left outside the class to achieve a quick but less accurate calculation of distance without instantiating a point object.
Point distance formulae adapted from and ©2002-2012 Chris Veness. Post titled Calculate distance, bearing and more between Latitude/Longitude points.
Equirectangular distance approximation formula.
Initial bearing / forward azimuth.
Point along great circle path given bearing and distance away.
Haversine distance formula.
Halfway point along a great circle path.
Equirectangular approximation formula without Point objects.
Derive N/S/E/W points at distance length away to compute bounds.
