This is a small JavaScript file to create latitude/longitude gridlines over Google Maps.
The original version was made by Bill Chadwick and then other contributors continued to improve it. Refer to the file's comment for more information.
I made some improvements and made this library available in Bower.
- Fix JSHint errors.
- Fix the issue that this library causes map to freeze in Chrome/Safari on Mac.
Use bower install google-maps-gridlines
to install using Bower.
To show gridlines on Google map, use code like this
var mapOptions = {
center: new google.maps.LatLng(-42, 174),
zoom: 5
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var gridlines = new Graticule(map);
To view example usage, check out test/simple-map.html
page. You can start a simple HTTP server using python -m SimpleHTTPServer
and view this sample page.
