Migrate Reverse Geocoding Requests

This section covers the actions that must be taken to migrate a HERE Geocoder API Reverse Geocoding request to a GS7 Reverse Geocode request.

For more details about the types or specification of parameters, see the Developer Guide.

Base URL, Version, Resource

Parameter HERE Geocoder API GS7
Base URL https://reverse.geocoder.api.here.com https://revgeocode.search.hereapi.com
Version /6.2 /v1
Resource / Endpoint /reversegeocode /revgeocode
Format specifier .xml -
.json -

HERE Geocoder API supports XML and JSON output formats. HERE Geocoding and Search v7 supports JSON output format only. The format specifier is therefore not required and must be omitted.

Query parameters

HERE Geocoder API GS7 comment
additionaldata=Country2 show=countryInfo
language lang List of languages is not supported.
locationattributes.streetDetails (sd) show=streetInfo
maxresult limit GS7 does not have the concept of multiple response pages. GS7 limit parameter limits total number of the results.
politicalview politicalview GS7 politicalview parameter accepts all uppercase single ISO 3166-1 alpha-3 country codes. The complete list of currently supported political views can be found at Supported Political Views. For any valid 3 letter country code, for which HERE Geocoding and Search does not have dedicated political view, it falls back to the default view.
prox at or in=circle GS7 at parameter does not support radius. Alternatively a circular spatial filter (in=circle:lat,lon;rad) can be used.
