如何使用纬度和经度坐标从一个位置获取时区？

StackOverflow关于parsing某个位置的时区有太多的问题。 这个社区维基是试图巩固所有有效的回应。

请更新我的答案，或者根据需要添加自己的答案。

问题
考虑到一个位置的经纬度，如何知道该位置的哪个时区是有效的？

在大多数情况下，我们正在寻找IANA / Olson时区标识，尽pipe一些服务可能只返回UTC偏移量或其他时区标识。 请阅读时区标签信息了解详细信息。

Answer 1

时区位置Web服务

• Google时区API
• GeoNames时区API
• TimeZoneDB API
• AskGeo – 商业（但可以说比GeoNames更准确 ）
• GeoGarage时区API – 商业，侧重于航海时区。

原始时区边界数据

• 时区边界生成器 – 从OpenStreetMaps地图数据生成时区shapefile。 包括海岸附近的领海。

以下项目以前是时区边界数据的来源，但不再积极维护。

• tz_world – 来自Eric Muller的原始shapefile数据
• wherewhere-时区 – 合并了WOEDB数据的GeoJSON版本

时区地理定位离线实施

使用时区边界生成器数据的实现

• node-geo-tz – JavaScript库
• tz-lookup – JavaScript库
• GeoTimeZone – .NET库
• timezonefinder – Python库

使用较旧的tz_world数据的实现

• latlong – 去图书馆（也读这篇文章 。）
• TimeZoneMapper – Java库
• tzwhere – JavaScript / Node库
• pytzwhere – Python库
• timezone_finder – Ruby库
• LatLongToTimeZone – Java和Swift库
• 现在几点钟？ – 描述PHP和MongoDB的博客文章

调用其中一个Web服务的库

• 时区 – 调用GeoNames的Ruby gem
• AskGeo拥有自己的库，可以从Java或.Net进行调用
• GeoNames拥有几乎所有的客户端库

其他想法

• 用R-Treefind最近的城市
• 使用MySQL查找最近的城市

如果您知道其他人，请更新此列表

另外请注意，最接近城市的方法可能不会产生“正确”的结果，只是一个近似值。

转换到Windows区域

列出的大部分方法都将返回一个IANA时区标识。 如果您需要转换为Windows时区以使用.NET中的TimeZoneInfo类，请使用TimeZoneConverter库。

不要使用zone.tab

tz数据库包含一个名为zone.tab的文件。 此文件主要用于显示用户从中select的时区列表。 它包括每个时区的参考点的纬度和经度坐标。 这允许创build地图来突出显示这些点。 例如，请参阅时区主页上显示的交互式地图。

尽pipe使用这些数据来parsing纬度和经度坐标的时区可能是很诱人的，但考虑到这些是点 – 而不是边界。 最好的办法是确定最接近的点，在许多情况下，这不是正确的点。

考虑下面的例子：

这两个方块表示不同的时区，每个方块中的黑点是参考位置，例如zone.tab中可以find的地方。 蓝点表示我们试图find时区的位置。 很显然，这个位置在左边的橙色区域内，但是如果我们只是看距参考点最近的距离，它将会解决到右边的绿色区域。

这个解决scheme如何node.js https://github.com/mattbornski/tzwhere

和它的Python对应： https ： //github.com/pegler/pytzwhere

Answer 3

我们在Teleport刚开始开放我们的API ，其中一个用例也暴露了TZ的坐标信息。

例如，可以按照以下方式请求我们所有可用的TZ信息：

 curl -s https://api.teleport.org/api/locations/59.4372,24.7453/?embed=location:nearest-cities/location:nearest-city/city:timezone/tz:offsets-now | jq '._embedded."location:nearest-cities"[0]._embedded."location:nearest-city"._embedded."city:timezone"' 

这将返回以下内容

 { "_embedded": { "tz:offsets-now": { "_links": { "self": { "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/offsets/?date=2015-09-07T11%3A20%3A09Z" } }, "base_offset_min": 120, "dst_offset_min": 60, "end_time": "2015-10-25T01:00:00Z", "short_name": "EEST", "total_offset_min": 180, "transition_time": "2015-03-29T01:00:00Z" } }, "_links": { "self": { "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/" }, "tz:offsets": { "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/offsets/{?date}", "templated": true }, "tz:offsets-now": { "href": "https://api.teleport.org/api/timezones/iana:Europe%2FTallinn/offsets/?date=2015-09-07T11%3A20%3A09Z" } }, "iana_name": "Europe/Tallinn" } 

对于我使用./jq进行JSONparsing的例子。

Answer 4

您可以使用geolocator.js轻松获取时区和更多…

它使用需要密钥的Google API。 所以，首先你configurationgeolocator：

 geolocator.config({ language: "en", google: { version: "3", key: "YOUR-GOOGLE-API-KEY" } }); 

获取时区，如果你有坐标：

 geolocator.getTimeZone(options, function (err, timezone) { console.log(err || timezone); }); 

示例输出：

 { id: "Europe/Paris", name: "Central European Standard Time", abbr: "CEST", dstOffset: 0, rawOffset: 3600, timestamp: 1455733120 } 

find然后获取时区等等

如果您没有坐标，可以先find用户位置。

下面的示例将首先尝试使用HTML5 Geolocation API来获取坐标。 如果失败或被拒绝，将通过Geo-IP查找得到坐标。 最后，它将获得时区和更多…

 var options = { enableHighAccuracy: true, timeout: 6000, maximumAge: 0, desiredAccuracy: 30, fallbackToIP: true, // if HTML5 fails or rejected addressLookup: true, // this will get full address information timezone: true, map: "my-map" // this will even create a map for you }; geolocator.locate(options, function (err, location) { console.log(err || location); }); 

示例输出：

 { coords: { latitude: 37.4224764, longitude: -122.0842499, accuracy: 30, altitude: null, altitudeAccuracy: null, heading: null, speed: null }, address: { commonName: "", street: "Amphitheatre Pkwy", route: "Amphitheatre Pkwy", streetNumber: "1600", neighborhood: "", town: "", city: "Mountain View", region: "Santa Clara County", state: "California", stateCode: "CA", postalCode: "94043", country: "United States", countryCode: "US" }, formattedAddress: "1600 Amphitheatre Parkway, Mountain View, CA 94043, USA", type: "ROOFTOP", placeId: "ChIJ2eUgeAK6j4ARbn5u_wAGqWA", timezone: { id: "America/Los_Angeles", name: "Pacific Standard Time", abbr: "PST", dstOffset: 0, rawOffset: -28800 }, flag: "ajax/libs/flag-icon-css/2.3.1/flags/4x3/us.svg", map: { element: HTMLElement, instance: Object, // google.maps.Map marker: Object, // google.maps.Marker infoWindow: Object, // google.maps.InfoWindow options: Object // map options }, timestamp: 1456795956380 } 

Answer 5

好的，这里是没有正确的NTP时间的短版本：

 String get_xml_server_reponse(String server_url){ URL xml_server = null; String xmltext = ""; InputStream input; try { xml_server = new URL(server_url); try { input = xml_server.openConnection().getInputStream(); final BufferedReader reader = new BufferedReader(new InputStreamReader(input)); final StringBuilder sBuf = new StringBuilder(); String line = null; try { while ((line = reader.readLine()) != null) { sBuf.append(line); } } catch (IOException e) { Log.e(e.getMessage(), "XML parser, stream2string 1"); } finally { try { input.close(); } catch (IOException e) { Log.e(e.getMessage(), "XML parser, stream2string 2"); } } xmltext = sBuf.toString(); } catch (IOException e1) { e1.printStackTrace(); } } catch (MalformedURLException e1) { e1.printStackTrace(); } return xmltext; } long get_time_zone_time_l(GeoPoint gp){ String raw_offset = ""; String dst_offset = ""; double Longitude = gp.getLongitudeE6()/1E6; double Latitude = gp.getLatitudeE6()/1E6; long tsLong = System.currentTimeMillis()/1000; if (tsLong != 0) { // https://maps.googleapis.com/maps/api/timezone/xml?location=39.6034810,-119.6822510&timestamp=1331161200&sensor=false String request = "https://maps.googleapis.com/maps/api/timezone/xml?location="+Latitude+","+ Longitude+ "&timestamp="+tsLong +"&sensor=false"; String xmltext = get_xml_server_reponse(request); if(xmltext.compareTo("")!= 0) { int startpos = xmltext.indexOf("<TimeZoneResponse"); xmltext = xmltext.substring(startpos); XmlPullParser parser; try { parser = XmlPullParserFactory.newInstance().newPullParser(); parser.setInput(new StringReader (xmltext)); int eventType = parser.getEventType(); String tagName = ""; while(eventType != XmlPullParser.END_DOCUMENT) { switch(eventType) { case XmlPullParser.START_TAG: tagName = parser.getName(); break; case XmlPullParser.TEXT : if (tagName.equalsIgnoreCase("raw_offset")) if(raw_offset.compareTo("")== 0) raw_offset = parser.getText(); if (tagName.equalsIgnoreCase("dst_offset")) if(dst_offset.compareTo("")== 0) dst_offset = parser.getText(); break; } try { eventType = parser.next(); } catch (IOException e) { e.printStackTrace(); } } } catch (XmlPullParserException e) { e.printStackTrace(); erg += e.toString(); } } int ro = 0; if(raw_offset.compareTo("")!= 0) { float rof = str_to_float(raw_offset); ro = (int)rof; } int dof = 0; if(dst_offset.compareTo("")!= 0) { float doff = str_to_float(dst_offset); dof = (int)doff; } tsLong = (tsLong + ro + dof) * 1000; } return tsLong; } 

和它一起使用：

 GeoPoint gp = new GeoPoint(39.6034810,-119.6822510); long Current_TimeZone_Time_l = get_time_zone_time_l(gp); 

Answer 6

如果你想使用geonames.org然后使用这个代码。 （但是geonames.org有时候很慢）

 String get_time_zone_time_geonames(GeoPoint gp){ String erg = ""; double Longitude = gp.getLongitudeE6()/1E6; double Latitude = gp.getLatitudeE6()/1E6; String request = "http://ws.geonames.org/timezone?lat="+Latitude+"&lng="+ Longitude+ "&style=full"; URL time_zone_time = null; InputStream input; // final StringBuilder sBuf = new StringBuilder(); try { time_zone_time = new URL(request); try { input = time_zone_time.openConnection().getInputStream(); final BufferedReader reader = new BufferedReader(new InputStreamReader(input)); final StringBuilder sBuf = new StringBuilder(); String line = null; try { while ((line = reader.readLine()) != null) { sBuf.append(line); } } catch (IOException e) { Log.e(e.getMessage(), "XML parser, stream2string 1"); } finally { try { input.close(); } catch (IOException e) { Log.e(e.getMessage(), "XML parser, stream2string 2"); } } String xmltext = sBuf.toString(); int startpos = xmltext.indexOf("<geonames"); xmltext = xmltext.substring(startpos); XmlPullParser parser; try { parser = XmlPullParserFactory.newInstance().newPullParser(); parser.setInput(new StringReader (xmltext)); int eventType = parser.getEventType(); String tagName = ""; while(eventType != XmlPullParser.END_DOCUMENT) { switch(eventType) { case XmlPullParser.START_TAG: tagName = parser.getName(); break; case XmlPullParser.TEXT : if (tagName.equalsIgnoreCase("time")) erg = parser.getText(); break; } try { eventType = parser.next(); } catch (IOException e) { e.printStackTrace(); } } } catch (XmlPullParserException e) { e.printStackTrace(); erg += e.toString(); } } catch (IOException e1) { e1.printStackTrace(); } } catch (MalformedURLException e1) { e1.printStackTrace(); } return erg; } 

和它一起使用：

 GeoPoint gp = new GeoPoint(39.6034810,-119.6822510); String Current_TimeZone_Time = get_time_zone_time_geonames(gp); 

Answer 7

通过使用纬度和经度得到当前位置下面的代码为我工作的时区

 String data = null; LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); Location ll = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); double lat = 0,lng = 0; if(ll!=null){ lat=ll.getLatitude(); lng=ll.getLongitude(); } System.out.println(" Last known location of device == "+lat+" "+lng); InputStream iStream = null; HttpURLConnection urlConnection = null; try{ timezoneurl = timezoneurl+"location=22.7260783,75.8781553&timestamp=1331161200"; //&key=AIzaSyDZMS5Za6yG_66gAK8PL_KH1ZSS9NbWC"; // timezoneurl = timezoneurl+"location="+lat+","+lng+"&timestamp=1331161200";//&key=AIzaSyDZMS5Za6yG_66gAK8PL_KH1ZSS9NbWCbg"; URL url = new URL(timezoneurl); // Creating an http connection to communicate with url urlConnection = (HttpURLConnection) url.openConnection(); // Connecting to url urlConnection.connect(); // Reading data from url iStream = urlConnection.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(iStream)); StringBuffer sb = new StringBuffer(); String line = ""; while( ( line = br.readLine()) != null){ sb.append(line); } data = sb.toString(); br.close(); }catch(Exception e){ Log.d("Exception while downloading url", e.toString()); }finally{ try { iStream.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } urlConnection.disconnect(); } try { if(data!=null){ JSONObject jobj=new JSONObject(data); timezoneId = jobj.getString("timeZoneId"); SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); format.setTimeZone(TimeZone.getTimeZone(timezoneId)); Calendar cl = Calendar.getInstance(TimeZone.getTimeZone(timezoneId)); System.out.println("time zone id in android == "+timezoneId); System.out.println("time zone of device in android == "+TimeZone.getTimeZone(timezoneId)); System.out.println("time fo device in android "+cl.getTime()); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } 

Answer 8

认识到这是一个比大多数人怀疑的更复杂的问题。 在实践中，我们中的许多人也愿意接受一套适用于“尽可能多的情况下”的代码，至less它的致命问题可以被识别并最小化。 所以我把这一切和OP的精神都记在脑子里。 最后，对于其他尝试将GPS转换为时区的用户来说，实际价值在于具有位置敏感时间对象的最终目标（更重要的是帮助提高具有此wiki的时间对象的平均实现的质量）我在Python中生成的内容（请随时编辑）：

 import pytz from datetime import datetime from tzwhere import tzwhere def timezoned_unixtime(latitude, longitude, dt): tzw = tzwhere.tzwhere() timezone_str = tzw.tzNameAt(latitude, longitude) timezone = pytz.timezone(timezone_str) timezone_aware_datetime = timezone.localize(dt, is_dst=None) unix_time = (timezone_aware_datetime - datetime(1970, 1, 1, tzinfo=pytz.utc)).total_seconds() return unix_time dt = datetime(year=2017, month=1, day=17, hour=12, minute=0, second=0) print timezoned_unixtime(latitude=40.747854, longitude=-74.004733, dt=dt) 

Answer 9

1. 有几个网上有geojson时区数据源（ 这里是一个 ， 这里是另一个）

2. 使用几何库从geojson坐标（shapely [python]， GEOS [c ++]， JTS [java]， NTS [.net]）创build多边形对象。

3. 将你的lat / lng转换成一个点对象（不过你的库代表那个），并检查它是否与时区多边形相交。

    from shapely.geometry import Polygon, Point def get_tz_from_lat_lng(lat, lng): for tz, geojson in timezones.iteritems(): coordinates = geojson['features'][0]['geometry']['coordinates'] polygon = Polygon(coordinates) point = Point(lng, lat) if polygon.contains(point): return tz
