我想知道是否有可能根据从GPS系统收集的纬度/经度信息或近似街道地址获取位置？ 在这种情况下，景点被定义为：餐馆，度假村，公园，购物中心，电影院等。
是否有一些在线服务使用bing maps / google maps /其他东西，以某种解析格式提供此类信息？
谢谢

在客户端，您使用Google AJAX Search API搜索特定坐标周围的景点：
<!DOCTYPE html>
<html>
<head>
<title>Google AJAX Search API Demo</title>
<script src="http://www.google.com/jsapi" type="text/javascript"></script>
<script type="text/javascript">
google.load('search', '1');
var localSearch;
function localSearchComplete() {
// Check that we got results
if (localSearch.results && localSearch.results.length > 0) {
// Loop through our results, printing them to the page.
var results = localSearch.results;
document.getElementById('content').innerHTML = "";
for (var i = 0; i < results.length; i++) {
document.getElementById('content').innerHTML +=
'<div style="clear: both;">' +
'<div style="float: left; width: 160px;">' + results[i].title + '</div>' +
'<div style="float: left; width: 80px;">' + results[i].lat + '</div>' +
'<div style="float: left; width: 80px;">' + results[i].lng + '</div>' +
'<div style="float: left; width: 140px;">' + results[i].streetAddress + '</div>' +
'<div style="float: left; width: 120px;">' + results[i].city + '</div>' +
'</div>';
}
}
}
function OnLoad() {
localSearch = new google.search.LocalSearch();
// Coordinates for "New York, NY"
localSearch.setCenterPoint("40.70, -74.00");
localSearch.setSearchCompleteCallback(this, localSearchComplete, null);
localSearch.execute("restaurants");
}
google.setOnLoadCallback(OnLoad);
</script>
</head>
<body style="font-family: Arial; font-size: 11px;">
<div id="content">Loading...</div>
</body>
</html>
结果如下：
Local Search Results http://img693.imageshack.us/img693/240/localsearch.png
要以JSON格式从服务器端获得相同的结果，您可能需要查看以下文章：
基本上，您可以按以下格式向Google发出请求：
http://ajax.googleapis.com/ajax/services/search/local?v=2.0&q=restaurants+40.70,-74.00
哪个会返回以下JSON：
