I'm trying to snap coordinate to nearest road. But still I can't do that in simple way.
This is simple code, how to improve it that result would be marker on the road:
<!DOCTYPE html>
<html>
<head>
<title>Map</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 300px; width:600px }
</style>
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
function initialize() {
var homeLatlng = new google.maps.LatLng(24.696554,-81.328238);
var myOptions = {
zoom: 15,
center: homeLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var image = new google.maps.MarkerImage(
'http://maps.google.com/mapfiles/ms/micons/green-dot.png',
new google.maps.Size(32, 32), // size
new google.maps.Point(0,0), // origin
new google.maps.Point(16, 32) // anchor
);
var shadow = new google.maps.MarkerImage(
'http://maps.google.com/mapfiles/ms/micons/msmarker.shadow.png',
new google.maps.Size(59, 32), // size
new google.maps.Point(0,0), // origin
new google.maps.Point(16, 32) // anchor
);
var homeMarker = new google.maps.Marker({
position: homeLatlng,
map: map,
title: "Check this cool location",
icon: image,
shadow: shadow
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map_canvas"></div>
</body>
</html>
I would like to get idea for easiest method. Thanks for any help.

Use the directions service. Get driving directions from the point of interest to the point of interest. Should be on the road.
var directionsService = new google.maps.DirectionsService();
directionsService.route({origin:homeLatlng, destination:homeLatlng, travelMode: google.maps.DirectionsTravelMode.DRIVING}, function(response, status) {
if (status == google.maps.DirectionsStatus.OK)
{
var homeMarker = new google.maps.Marker({
position: response.routes[0].legs[0].start_location,
map: map,
title: "Check this cool location",
icon: image,
shadow: shadow
});
} else {
var homeMarker = new google.maps.Marker({
position: homeLatlng,
map: map,
title: "Check this cool location",
icon: image,
shadow: shadow
});
}
});
