本文介绍了我能否知道坐标是否在城市内部?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用Google Map V3。
解决方案
您是否尝试过反向地理编码? b

您可以查看格式化的地址,重新寻找。我不确定这对您的应用程序有多准确,但它是一个选项。
$ b
(),
latlng = new google.maps.LatLng(40.730885,-73.997383);
geocoder.geocode({'latLng':latlng},function(results,status){
if(status == google.maps.GeocoderStatus.OK){
if(results [1 ]){
console.log(results [1]);
console.log(results [1] .formatted_address);
}
} else {
alert (Geocoder失败,原因是:+状态);
}
});
}
Let's say I have a LatLng object, is there any way of checking if it represents a possible location within a city? How can I get the limits of a city? I'm using Google Map V3.
解决方案
Have you tried reverse geocoding?
http://code.google.com/apis/maps/documentation/javascript/services.html#ReverseGeocoding
You could check the formatted address to see if the city matches what you're looking for. I'm not sure how accurate this will be for your application, but it's an option.
function codeLatLng() {
var geocoder = new google.maps.Geocoder(),
latlng = new google.maps.LatLng(40.730885, -73.997383);
geocoder.geocode({ 'latLng': latlng }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
console.log(results[1]);
console.log(results[1].formatted_address);
}
} else {
alert("Geocoder failed due to: " + status);
}
});
}
