let y = conversions.latToY(lat, altC); //converts latitude to y, an alternative center can be provided in lat units
let lon = conversions.xToLon(x, altC); //converts x to longitude, an alternative center can be provided in lon units
let lat = conversions.yToLat(y, altC); //converts y to latitude, an alternative center can be provided in lat units
