Поиск достопримечательностей по приблизительному географическому положению

2 голосов
/ 28 февраля 2010

Мне было интересно, можно ли получить достопримечательности в месте на основе информации о широте / долготе или приблизительного адреса улицы, полученного из системы GPS? Интересные места в этом контексте определяются как: рестораны, курорты, парки, торговые центры, кинотеатры и т. д.

Существуют ли какие-либо онлайн-сервисы с картами bing / google maps / что-то еще, которые предоставляют такую ​​информацию в каком-то разобранном формате?

Спасибо

На стороне клиента вы используете Google AJAX Search API для поиска достопримечательностей по определенной координате: 

<!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>

Результат будет следующим:

Чтобы получить те же результаты со стороны сервера в формате JSON , вы можете проверить следующую статью:

Как правило, вы сможете отправить запрос в Google в следующем формате:

http://ajax.googleapis.com/ajax/services/search/local?v=2.0&q=restaurants+40.70,-74.00

Что вернет следующий JSON:
