  24. 24. Map APIs : pros and cons Pros Cons Google Map First Ajax based brilliant looking map Only Javascript libray International base map (Europe, Japan) Detail world-wide aerial photos Largest developer based APIs Lots of hacks and mash-up Yahoo! Map First external geocoding capability U.S. and Canada only Very flexible and open API's Flyouts not quite as spiffy as Google Rate limiting by IP instead of appID GeoRSS support Flash/Flex version available AOL MapQuest Frist routing (driving directions) capability No smooth Ajax client (yet) Geocoding capability Slow functional changes Large users and big market share Weak documentations Microsft Virtual Well documented and sample sites Low Performance Earth Detail Building shape and 3D view 24

Google Map API Code <script type=quot;text/javascriptquot; src=quot;http://www.google.com/jsapi?key=ABCDEFGquot;></script> <script type=quot;text/javascriptquot;> google.load(quot;mapsquot;, quot;2.xquot;); // Call this function when the page has been loaded function initialize() { var map = new google.maps.Map2(document.getElementById(quot;mapquot;)); map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13); } google.setOnLoadCallback(initialize); </script> 25
