1、简介
地理编码 (Geocoding)是一个街道、地址或者其他位置（经度、纬度）转化为坐标的过程。反向地理编码 (Reverse geocoding)是将坐标转换为地址（经度、纬度）的过程。一组反向地理编码结果间可能会有所差异。例如：一个结果可能包含最临近建筑的完整街道地址，而另一个可能只包含城市名称和邮政编码。
2、百度
- 拾取坐标系统
https://api.map.baidu.com/lbsapi/getpoint/index.html 1、支持地址 精确/模糊 查询；
2、支持POI点坐标显示、复制；
3、坐标鼠标跟随显示；
4、 支持坐标查询(需要将坐标反查框勾选)； - Geocoding API
https://api.map.baidu.com/lbsapi/cloud/webservice-geocoding.htm
Geocoding API 是一类简单的HTTP接口，用于提供从地址到经纬度坐标或者从经纬度坐标到地址的转换服务，用户可以使用C# 、C++、Java等开发语言发送HTTP请求且接收JSON、XML的返回数据。
Geocoding API包括地址解析和逆地址解析功能。
- 地理编码：即地址解析，由详细到街道的结构化地址得到百度经纬度信息，且支持名胜古迹、标志性建筑名称直接解析返回百度经纬度。例如：“北京市海淀区中关村南大街27号”地址解析的结果是“lng:116.31985,lat:39.959836”，“百度大厦”地址解析的结果是“lng:116.30815,lat:40.056885”
- 逆地理编码，即逆地址解析，由百度经纬度信息得到结构化地址信息。例如：“lat:31.325152,lng:120.558957”逆地址解析的结果是“江苏省苏州市虎丘区塔园路318号”。
百度地图Geocoding API是一套免费对外开放的API，无使用次数限制。使用方法：
- 第一步：申请ak（即获取密钥），若无百度账号则首先需要注册百度账号。
- 第二步，拼写发送http请求的url，注意需使用第一步申请的ak。
- 第三步，接收http请求返回的数据（支持json和xml格式）。

这里通过编写Python脚本实现地理编码功能如下：

4、google map
https://developers.google.com/maps/documentation/javascript/geocoding
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var mapOptions = {
zoom: 8,
center: latlng
}
map = new google.maps.Map(document.getElementById('map'), mapOptions);
}
function codeAddress() {
var address = document.getElementById('address').value;
geocoder.geocode( { 'address': address}, function(results,) {
if (status == 'OK') {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
<body onload="initialize()">
<div id="map" style="width: 320px; height: 480px;"></div>
<div>
<input id="address" type="textbox" value="Sydney, NSW">
<input type="button" value="Encode" onclick="codeAddress()">
</div>
</body>
Here is a typical example of retrieving a Lat & Lng from Google using Python,
things shouldn’t be this hard.
import requests
url = 'https://maps.googleapis.com/maps/api/geocode/json'
params = {'sensor': 'false', 'address': 'Mountain View, CA'}
resp = requests.get(url, params=params)
results = resp.json()['results']
location = results[0]['geometry']['location']
location['lat'], location['lng']

5、nominatim
https://nominatim.org/
Nominatim：Open-source geocoding with OpenStreetMap data
Nominatim uses OpenStreetMap data to find locations on Earth by name and address (geocoding). It can also do the reverse, find an address for any location on the planet.
5.1 overview
- Geocoding
Find places by name or address (Geocoding)：
Nominatim can power the search box on your website, allowing your users to type free-form queries (“Cafe Paris, New York”) in any language. It also offers a structured query mode (“postcode=12345”, “city=London”, “type=cafe”) that helps you to automate geocoding of extensive address lists. - Reverse geocoding
Look up addresses for a location (Reverse geocoding)
Given a latitude and longitude anywhere on the planet, Nominatim can find the nearest address. It can do the same for any OSM object given its ID.
5.2 web api
https://nominatim.org/release-docs/develop/api/Overview/
Nominatim indexes named (or numbered) features within the OpenStreetMap (OSM) dataset and a subset of other unnamed features (pubs, hotels, churches, etc).
Nominatim API，Its API has the following endpoints for querying the data:
- /search - search OSM objects by name or type
- /reverse - search OSM object by their location
- /lookup - look up address details for OSM objects by their ID
- /status - query the status of the server
- /deletable - list objects that have been deleted in OSM but are held back in Nominatim in case the deletion was accidental
- /polygons - list of broken polygons detected by Nominatim
- /details - show internal details for an object (for debugging only)
http://localhost:8088/status.php
http://localhost:8088/search.php?q=Berlin
http://localhost:8088/reverse.php?lat=27.1750090510034&lon=78.04209025

6、geocode
Many online providers such as Google & Bing have geocoding services,
these providers do not include Python libraries and have different
JSON responses between each other.
It can be very difficult sometimes to parse a particular geocoding provider
since each one of them have their own JSON schema.

https://geocode.maps.co/reverse?lat={latitude}&lon={longitude}
7、geocoder
Geocoder is a simple and consistent geocoding library.
https://pypi.org/project/geocoder/
