Google Maps - how to specify starting point

daymobrew · 22-03-2006 12:14PM #1

I wrote some Javascript to allow me to create a URL that would display a map and marker to a specified location. It's useful when telling a local authority the location of a broken traffic light or pothole.
Unfortunately the URL is quite long.

I've seen people make use of the Google Maps site to do something similar, but I can't remember where I saw this. Anyone know what GET parameters the site uses and how the coordinates are generated?

Thanks for the link. Via it I found YourGMap which has given be an idea. I'll store my links in a database and provide a shorter url to view them and include a caption for the marker.

Hi,

I used google maps on my rugby club's website - the API is easy enough to use. Finding the starting point wasn't too bad, I just went to the google maps page and found the spot I wanted, and made it the centre of the map. I then clicked the "link to this page" link, and that gave me the URL with the coordinates.

Then I just added them to the JavaScript that generates the map:

// center the map:
map.centerAndZoom(new GPoint(-6.139083,53.259617), 2);
// add a marker:
var point = new GPoint(-6.139083,53.259617);
var marker = new GMarker(point);
