How do I define the response match level to prevent a street level search
I am trying to geotag a number of Mexican towns/suburbs using the town/suburb name, the district, and the suburb. that is all i have available to me.
an example of this is:
El Pentagono,Tamaulipas,Aldama
(town) (state) (district)
This winds up as the following query:
https://geocoder.api.here.com/6.2/geocode.json?gen=9&jsonattributes=1&app_code=[app_code]&app_id=[app_id]&country=MX&responseattributes=parsedRequest&searchtext=El Pentagono,Tamaulipas,Aldama
which returns a street level match...
(edited highlights)
"relevance": 1,
"matchLevel": "street",
"matchQuality": {
"country": 1,
"state": 1,
"city": 1,
"street": [0.9]
"address": {
"label": "Carretera a El Pentagono, 89670 Aldama, TAMPS, México",
"country": "MEX",
"state": "TAMPS",
"city": "Aldama",
"street": "Carretera a El Pentagono",
"postalCode": "89670",
so it has matched on a street, rather than the town/suburb of El Pentagono. So how do I tell the API... "no way Jose, give me a town/suburb on El Pentagono, and leave it at that. Don't go looking at streets".
Any help/advice would be awesome

One possibility to get the admin hierarchy for a location is to call the Reverse Geocoder with mode=retrieveAreas by using the coordinates you got from the Forward Geocoder response.
mode=retrieveAreas
retrieveAreas - Retrieve the administrative area information for the
position provided in the request
See https://developer.here.com/documentation/geocoder/topics/resource-reverse-geocode.html for details.
Oh hang on... i just reread your response... As you can see in my original post above, my query contains the town, state and area. (El Pentagono,Tamaulipas,Aldama). So i already have the administrative areas. admin1 and admin2. The response is returning El Pentagono street in Aldama. I need the centroid for El Pentagono (the suburb). So i need the API to stop at the town/district level. The lat long for Carretera a El Pentagono (El Pentagono) is different to the lat long for El Pentagono. I can provide further examples if need be.

Theoretically, that might work. but where the town returned on the forward lookup is incorrect (ie: the API has returned a street name match in a different town or a different state), then the lat/long will be wrong, and the reverse lookup will return the incorrect state. I am looking to do this for approximately 85,000 locations, so its unlikely such errors will be picked up easily, and will corrupt our final dataset.
