I am trying to backwards geocode Lat/Lng and get the nearest street address. However this is not always going to be completely accurate. I need to know if it is possible to get more than just one near street address.
Here is what I have that only gives one full street address result.
function locationizer(position){
latitude = position.coords.latitude;
longitude = position.coords.longitude;
latlng = new google.maps.LatLng(latitude,longitude);
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: latlng,
zoom: 15
});
var request = {
address: latlng,
radius: '100',
types: ['street_address']
};
geocoder.geocode({'latLng': latlng}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
map.setZoom(11);
console.log(results);
for(var loc in results){
$("#output").append(results[loc].formatted_address+"<br />");
}
} else {
alert("Geocoder failed due to: " + status);
}
});
}
Example Output
100 S High St, New Albany, OH 43054, USA
New Albany, OH, USA
Plain, OH, USA
New Albany, OH 43054, USA
Franklin, OH, USA
Ohio, USA

I am finding a location using google API and then calculating the distance between the searched place and the particular hotel which is coming from my data base, In image you can see i have searched for route map and distance for "Leela Palace Bengaluru, HAL Airport Road, ISRO Colony, Bengaluru, Karnataka, India" to my hotel which is coming from data base,as you can see the marker is not exactly pinning on leela palace instead it is showing next to the leela palace that is marked as B in image. I don't know where exactly i have done wrong it would be great if someone can help me with this thank you
Map response
"Leela Palace Bengaluru, HAL Airport Road, ISRO Colony, Bengaluru, Karnataka, India" is a place, not a postal address. When you send that string to the geocoder you get a result for "Leela Palace Rd, HAL 3rd Stage, Bengaluru, Karnataka, India (12.9619947, 77.64936599999999)"
The geocoder is for postal addresses.
The Places API/library is for places.
The distance service uses the geocoder for strings, if you give it a place ID, it will use that for the destination.
Using the place id finder, the place id for "Leela Palace Bengaluru" is:
The Leela Palace Bengaluru
Place ID: ChIJ3ZvKfAYUrjsRGuckzDe-GxE
23, HAL Airport Rd, ISRO Colony, Domlur, Bengaluru, Karnataka 560008, India
You can use that for the destination of the DirectionsService.

Is there a way to request main road Google StreetView panorama data instead of back alley panorama data for a given location (latitude/longitude)?
I'm using the Google Maps Javascript API to retrieve a street view panorama from a home address supplied by our users. It works quite well for most addresses I've tried, but I'm noticing a lot of properties in California also have street views for back alleys, and the API seams to be consistently returning the back alley panorama instead of the main road (front of property) panorama.
I don't want to show the user a back alley panorama of their home, but instead the main road panorama. If I lookup the same address on maps.google.com I see the front of the house, but when I request the same address through the API I get the back alley.
The process I'm currently using is:
Geocode address
Get panorama given the geocode location (lat/long)
Compute heading and display panorama on page
Test Addresses:
325 S Peck Dr, Beverly Hills, CA, USA, 90212
333 S Rodeo Dr, Beverly Hills, CA, USA, 90212
Any ideas or suggestions would be greatly appreciated. Thanks!
Use the directions service to get directions from the desired address to itself. Use that location instead of the geocoder result for the street view location. Use the geocoder result (hopefully a ROOFTOP accuracy result) for the place to look "at".

How would you limit your search to a county in below query?
geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'address': address }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
I've tried formatting an object like this:
{
address: '389 george st, sydney'
county: au
}
But if I search for 'poo' for instance India comes up in the results. How would I limit to only search in Australia?
You need to do region code biasing.
The query must be specific to the area you want to search.
This is the example given by Google.

I'm using Google Maps to place markers from an array of zip codes but it only places about 10% of them. The rest return null results. I can't find the problem. Here is my code.
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&language=en"></script>
<script type="text/javascript">
var latlng = new google.maps.LatLng(37.09024, -95.712891);
var map = new google.maps.Map(document.getElementById('pledge-map'), {
zoom: 4,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var geocoder = new google.maps.Geocoder();
var locations = <?php echo(json_encode($zips)); ?>
for (var i = 0; i < locations.length; i++) {
geocoder.geocode( { 'address': locations[i]}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var marker = new google.maps.Marker({
position: results[0].geometry.location,
map: map
});
}
});
}
</script>
locations is an array of zip code:
locations =["20190","22192","20148","06078","95136","84120","53066","53404","48323","52404","72762","89701","39667","78073","78016","76013","15613","84010","77662","77407","30127","94566","14625","45629","27406","27289","02339","01864","39116","77079","10954","37683","72801","19341","14580","64133","29579","08527","32258","33433","60093","76691","78261","77095","19426","10469","92038","85208","67220","61031","85706","72223","21222","66224","34242","30224","56232","32746","08558","72712","14209","43015","52722","32779","33518","33578","60565","11239","17007","60623","77469","20165","20002","36116","20769","20815","34209","02301","60025","48158","38804","30736","01803","45040","48069","07463","53018","73008","80951","70785","72065","91510","91506","67209","22408","36849"]
The geocoder is subject to a quota and rate limits. you are not checking for the error case (there is no code if the status returned is not OK).
Either:
look for the quota exceeded error code and handle it intelligently (add a delay and retry, only add the marker if it succeeds)
geocode the zipcodes offline and store the coordinates, use those to display your markers.
I'm using the Google Maps API (v2) and would like to center the map onload to a country (for example england).
At the moment i center the map using:
map.setCenter(new GLatLng( 43.907787,-79.359741), 9);
But this obviously requires longitude and Latitude.
Any way to do this by inserting a name of a country?
var country = "United States"
var map = new GMap2($("#map")[0]);
map.setUIToDefault();
var geocoder = new GClientGeocoder();
geocoder.getLatLng(country, function (point) {
if (!point) {
// Handle error
} else {
map.setCenter(point, 8, G_PHYSICAL_MAP);
}
});
You need to geocode the address first:
var geocoder = new google.maps.Geocoder();
var location = "England";
geocoder.geocode( { 'address': location }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
} else {
alert("Could not find location: " + location);
}
});
Turning a location name or address into a latitude/longitude like this is called geocoding. Google Maps API now includes this capability: see http://code.google.com/apis/maps/documentation/services.html#Geocoding
They include a sample application where you can type in an address, and it does work to simply type a country name. I don't know if they are going to the exact center of the country.
