如何提高 Google 地理编码器响应的精度？答案

【问题标题】：How can I increase the precision of the Google Geocoder Response?如何提高 Google 地理编码器响应的精度？
【发布时间】：2015-10-06 17:54:06
【问题描述】：

我使用 Google Geocoder 编写了两个测试：一项测试只是请求给定地址的地理点，

而第二个获取从谷歌检索的地理点并尝试获取地址。

我的问题是，在地址中谷歌返回给我的地址与它自己的（地理点）不一样！总结一下; 我的地址：Hirtenstraße 4, 10178 Berlin, Germany

Google 的地理点：lat = 52.5257827,lng = 13.4113952

谷歌返回地址：Hirtenstraße 4, 10178 Berlin, Germany

我的问题：有没有办法控制（提高）您返回的地理点结果的精度？

// ####### example code below################################################
@Test
 public void testGetPoints() throws IOException {
    final Geocoder geocoder = new Geocoder();

    String land = "Germany";
    String city = "Berlin";
    String streetAddress = "4 Hirtenstraße";
    String postcode = "10178";

    String fullAddress = streetAddress + ",+" + postcode + ",+" + city + ",+" + land;
    fullAddress = fullAddress.replace(" ", "+");

    GeocoderRequest geocoderRequest = new GeocoderRequestBuilder().setAddress(fullAddress).setLanguage("en").getGeocoderRequest();
    GeocodeResponse geocoderResponse = geocoder.geocode(geocoderRequest);
    ArrayList<GeocoderResult> addresses = new ArrayList<>(geocoderResponse.getResults());

    for (GeocoderResult r : addresses) {
        System.out.println(r.getGeometry().getLocation());
    }
}


@Test
public void testGeocoder() throws IOException {
    ArrayList<GeocoderResult> addresses = new ArrayList<GeocoderResult>();
    GeocodeResponse geocoderResponse;
    Geocoder geocoder = new Geocoder();

    // geo points we get from the previous test
    BigDecimal lat = new BigDecimal(52.5257827);
    BigDecimal lng = new BigDecimal(13.4113952);

    GeocoderRequest geocoderRequest = new GeocoderRequestBuilder().setLocation(new LatLng(lat, lng)).setLanguage("en").getGeocoderRequest();

    geocoderResponse = geocoder.geocode(geocoderRequest);
    addresses.addAll(geocoderResponse.getResults());

    for (GeocoderResult r : addresses) {
        System.out.println(r.getFormattedAddress());
        // first value returns:
        // Hirtenstraße 5, 10178 Berlin, Germany !!!!!  not 4!
    }
}

【解决方案1】：

结果是：

"location_type": "RANGE_INTERPOLATED"

所以它不会是精确的，它是插值的。您需要一个具有“ROOFTOP”结果的地理编码器结果，但 Google 的地理编码器（还没有）。

完整的地理编码器响应：
