如何找到一个给定区域的长纬度，用针code

问题描述

您好，我使用Bing地图在我的网站，并希望长期经纬度精确定位在Bing地图的位置。我的问题是在我的网站我怎样才能纬度长时间使用脚code的区域。是否有任何的API，我可以用它来给予销区code纬度长的查询用。我想这样做在后台。使用一些Ajax调用特定的Web API，并取回土地增值税郎并将其保存到数据库中，这样我可以使用纬度长在我的Bing地图绘制的位置。

hi i am using Bing map in my website and want lat long to pinpoint that location on Bing map. my question is in my website how can i get lat long of an area using pincode. Is there any api that i can use to query lat long with by giving area pin code. i want to do it in backend. using some ajax call to that particular web api and get back lat lang and saved it into database so that i can use that lat long to plot location on my bing map.

我使用Bing地图7，我需要把经纬度值长成JSON对象，并把它传递到Bing地图。

i am using bing map 7 where i need to put lat long value into a json object and pass it into Bing map.

function GetMap()
{
var mapOptions = {
credentials: "Your Bing Maps Key",
center: new Microsoft.Maps.Location(47.592, -122.332), // i want these value in my         database
mapTypeId: Microsoft.Maps.MapTypeId.birdseye,
zoom: 17,
showScalebar: false
}
var map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), mapOptions);
}

我可以硬code，但在我的应用程序给客户一个选择是使用添加新的位置，以便在后端我希望它喜欢当客户端会自动添加任何新的位置，将其保存其经纬度长也。

i can hard code it but in my application i have given client an option which is use to add new location so in back end i want it like when client add any new location it automatically save its lat long also.

感谢

推荐答案

使用针codeS获得的纬度，长的值可能不是最好的解决方案，因为针codeS，虽然流行了一个多世纪依然的环游世界。例如在美国的针codeS（邮政编码codeS）通常有5位（即06160），并在我的世界的一部分，他们通常是6位数以上。

Using pincodes for obtaining the lat, long values may not be the best solution, since pin codes though popular for more than a century are still not a standard round the world. for example in US pincodes (zip codes) are normally have 5 digits (i.e. 06160) and in my part of the world their are normally 6 digits or more..

虽然你可以使用街道地址，州，国家和引脚code的组合，找出近正确的地理坐标为世界上几乎每一个部分。请参阅下面的脚本，调用谷歌的API找到纬度，龙价值......这里由我捐这code向社会GPL下： -

Though you can use combination of street address, state, country and pin code to find out the nearly correct geo coordinates for almost every part of the world. See following script which calls google api for finding the Lat, Long value... Here by I donate this code to the community under GPL:-

        function submitFunc(){
            var location = prepareQuery();
            geocoder.getLocations(location, function (response) {
                if (!response || response.Status.code != 200)

                    var items = [];
                    $.each(location1, function(key, value){

        }

    </script>

和html的样子......

and the html looks like....

        Line 1   : <input type="text" id="address1" value="" placeholder="Enter first line of address."/> <br></br>
        Line 2   :<input type="text" id="address2" value="" placeholder="Enter second line of address."/> <br></br>
        Line 3   :<input type="text" id="address3" value="" placeholder="Enter third line of address."/> <br></br>
        City     : <input type="text" id="city" value="" placeholder="Enter city name."/> <br></br>
        State    : <input type="text" id="state" value="" placeholder="Enter state name."/> <br></br>
        Country  : <input type="text" id="country" value="" placeholder="Enter country name."/> <br></br>
        Pin Code : <input type="text" id="pincode" value="" placeholder="Enter pincode value."/> <br></br>
        <input type="button" name="submitBtn" value="submit" onclick='submitFunc();'/> <br></br>
