Geocoder API China - BETA Developer's Guide

Reading a Geocoding Response

The Geocoder API China - BETA has the following basic response structure.

A MetaInfo object that lists meta information about the request, such as the RequestId, Timestamp, and other additional data
A View object that groups search results, where the ViewId acts as a key to distinguish between different types of views
One or more Result objects containing the resulting items found along with attributes that determine the quality of the search result, such as:
- Relevance – a value from 0 to 1 representing the percentage of the input that matched the returned address. "1" means that all input tokens were matched.
- Distance – the distance, in meters, between the identified location object and the specified client position
- Direction – the direction of the location object as seen from the specified client position measured clockwise in degrees starting with 0 at true north
- MatchLevel – the most detailed address field that matches the geocoding or reverse geocoding query
- MatchQuality – attribute level information about the match quality; always 1.0 for reverse geocode results
- MatchType – quality of the location match, either pointAddress or interpolated
- Location – the location that was found, with the LocationId, LocationType, Address and so on
