google-maps-coords
Convert Google Maps Coordinates without Google Maps. Handles conversions between lat long, point, and px.
var coords = ; var zoom = 12; // zoom level of Google Mapsvar LL = 43669662 -79282848; // Latitude and Longitudevar PX = 29335996770986664 38261679057958454;var POINT = 7162108586666666 9341230238759388; coords;coords;coords;coords;coords;coords;
Usage
var coords = require('google-maps-coords');
Will return an object with the conversion functions. The functions are:
llToPX(latLong, zoom)
llToPoint(latLong)
pxToLL(latLong, zoom)
pxToPoint(pxCoord, zoom)
pointToPX(point, zoom)
pointToLL(point)
These functions can individually be required:
var llToPX = require('google-maps-coords/llToPX');
coords.llToPX(latLong, zoom)
Converts latitude and longitude values to pixel values. latLong
is an Array
where the first index is latitude and second is longitude. zoom
is the zoom level of the map for instance Google Maps zoom levels are between: 0-18.
The return value will be an array [x, y]
.
coords.llToPoint(latLong)
Converts a latitude and longitude to a point. The format of latLong is described in the documentation for coords.llToPX(latLong, zoom)
.
coords.pxToLL(latLong, zoom)
Converts a latitude and longitude to a pixel cordinate. The format of latLong and zoom are described in the documentation for coords.llToPX(latLong, zoom)
.
coords.pxToPoint(pxCoord, zoom)
Converts pixel values to Point values. pxCoord
will be an array [x, y]
. zoom
is described in the documentation for coords.llToPX(latLong, zoom)
.
Converts a latitude a
coords.pointToPX(point, zoom)
Converts Point values to pixel values. zoom
is described in the documentation for coords.llToPX(latLong, zoom)
.
coords.pointToLL(point)
Converts a point to a latitude and longitude.
