Guess projection

Find the geographic projection which best turns a given (X,Y) into an expected (lng, lat).

Returns an array of { projection, distance, def }, reverse sorted by distance. So the best guess for the name of the projection is results[0].projection.

const guess = require('guess-projection');
const results = guess(16137423.630081, -4553353.774948, 144.9, -37.85)
console.log(results[0]);
