Retrieve co-ordinates of points from a saved google map

Question

My client has saved a public Google Map with several points of interest marked on it. I need to somehow lift those co-ordinates and put them in an iPhone Google Map. How would I get the longitude & latitude of each of these points?

You can follow the following steps to access the KML for saved places in a My Maps account:

Go to My Maps and select the entry. Click the edit button on the left. This will expose a View in Google Earth link on the top right of the map. If this is a shared map, then the View in Google Earth link might already be available.

Clicking this link will download a file that looks something like this:

<?xml version="1.0" encoding="UTF-8"?>    
<kml xmlns="http://earth.google.com/kml/2.2"&gt;
<Document>
<name>Directions to Scone, NSW</name>
<description><![CDATA[]]></description>
    <NetworkLink>
    <name>Directions to Scone, NSW</name>
    <Link>
    <href>http://maps.google.com/maps/ms?ie=UTF8&amp;amp;hl=en&amp;amp;vps=1&amp;amp;jsv=262a&amp;amp;oe=UTF8&amp;amp;msa=0&amp;amp;msid=109115301202341389527.00048cf92603b4141b1cf&amp;amp;output=kml&lt;/href&gt;
    </Link>
    </NetworkLink>
</Document>
</kml>

Replace all the escaped & with & in the URL in the href element and request the URL in the browser. This will give you the KML that you are after:

http://maps.google.com/maps/ms?ie=UTF8&hl=en&vps=1&jsv=262a&oe=UTF8&msa=0&msid=109115301202341389527.00048cf92603b4141b1cf&output=kml
