jtejido/geodesy-php

Geodesy PHP - Port of some known geodesic/math functions for getting distance from a known point A to a known point B given their coordinates. It also supports conversion between units of length, Polar position to Cartesian coordinates, and different Reference Datums.

geodesy-php's Issues

Fetch for Datum updates via EPSG API

The Geographical Datum is fetched from a script I created a while back and realized that I haven't updated these since day 1. In order to avoid devs having to hardcode 'specific' datum (which leads to miscalculations) with updated ones (say, they only updated WGS when others have been left outdated, which leads to wrong transformations), it only makes sense to have to clean the script I initially used and upload it here on its own namespace.

Reference link/s for some distance calculations are broken

Some of these calculations' reference/s have been fetched from a mirror that hasn't been maintained for so long that they are closed now. Find these references and host them here (if possible).

Undefined variable: $cosSqAlpha

The $cosSqAlpha variable used in line 97 of src/Geodesy/Distance/VincentyFormula.php can be undefined if condition in line 63 is fulfilled.
