I currently have a POC working that retrieves places information using the Places HERE api by passing Lat and Long values. Our addresses are being converted to lat and long before the api is called and we fear we might be losing precision in the process. Instead of feeding the API the coordinates, is there a way to send the actual address and get the address information back? Business name, type, etc?
res = requests.get('https://places.cit.api.here.com/places/v1/discover/here?app_id=<>&app_code=<>&at='+str(lat)+','+str(long))
Based on what I see in the API docs (https://developer.here.com/documentation/places/dev_guide/topics_api/resource-search.html) the answer is no. You can see more detail here as well: https://developer.here.com/documentation/places/dev_guide/topics/location-contexts.html. Is there a particular example of where you think geocoding is returning bad results?
Use Geocoder API to get coordinates for address and then use these coordinates to make a request to Places API.

I am trying to geocode a street interception through Here Geocoder API Forward Geocoding. However, with no success.
There is some example in the documentation:
https://developer.here.com/api-explorer/rest/geocoder/latitude-longitude-intersection
There is an obvious way to do what I want.However, there is a proxy endpoint, which I am not allowed to change and it accepts from client and passes to Here API only free form input.
I tried with the following string for my free form input value,it is the same as the documentation example:
State # Madison, Chicago
But got 0 results.
I just wonder if that is possible at all through Here Forward Geocoding-it seems difficult for implementation without some restriction to the free-form input format?Thanks in advance!
I got the result for street intersection with it, can you please try by using your appkey, id.
https://geocoder.api.here.com/6.2/geocode.json?city=Chicago&street=State%20and%20Madison&app_id=xxxx&app_code=xxxx&gen=9
if the search needs to be in free form, then below API call can work too, but here the search match level is based out of the city, not specific to street.

I'm using contentful and want to convert some entry fields into more human readable content.
For example: I have a content type that has a field "location" that stores latitude and longitude. For us to display that in the app, i need that data to be converted into an adress. This can be done using the Google Maps API. How can I use the Google Maps API (or a third party API for other conversion cases) without having to build my own backend which retrieves data from contentful and then converts it.
Is there a way to do this with contentful?
Kind regards,
Erik
There is no way to do this with Contentful, it just allows you to store and retrieve that data.
But depending on your use case you could also use the Google Maps client side SDKs (iOS/Android/JS) to do this.
It seems that the Routing API requires a Lat/Lon pair to be supplied to the Waypoint parameter. I've seen other APIs that allow for the actual address to be passed, instead of the Lat/Lon. I'm wondering if anyone knows of a way to do this with the Here.com API. In many instances I can obtain the Lat/Lon first, but in one instance it's proving to be a headache, especially given the nature of the way that the REST APIs work and the fact that I'm trying to batch-process a small group of addresses at a single time. Any help would be appreciated.
Unfortunately Routing API needs a waypoint in lat, lon and required a Geocoding as a pre-requisite.
Maybe a not so nice workaround if you are facing issues with Geocoding, the Duck Duck Go provides a syntax

But you will stll have to extract the lat,lon from the final redirected url.
I am building an Events site in which the address of a given event will be stored to be used within a map on the page. Whilst viewing an Individual Events' page i would like to provide a list of similar events on side of the page. I would also like to rank this list by distance and display a small map with a marker on it for each item on the list.
I was thinking of Geocoding the Events address upon content input and then storing this data within the sites database. Doing this would allow me to calculate the distance of an event on the server and then provide an ordered list to display.
My question is this:
Would this violate the Googlemaps Terms of Service?
These terms:
"the geocoder for any purpose other than obtaining locations that will be displayed using the Google Maps APIs is a violation of the Terms of Service. You may use the HTTP geocoder to geocode addresses outside of your Google Maps API application so that they may be cached and later displayed using one of the Google Maps APIs, but locations obtained using the Geocoding Web Service may not be used by any other application, distributed by other means, or resold."
Suggest that storing the data is not a problem but i am unsure that the process of ordering the list by long lat would not result in a violation.
Any advice would be greatly appreciated.
As long as the map your refer to in your question is a Google Map and you are using the geocoded data to display features on a Google Map, you are fine. The client-side google.maps.Geocoderdev-guide is intended for dynamic requests that are based on real-time user interaction that drives a need to perform on-the-fly geocoding. But Google encourages you to consider using the Geocoding Web Servicedev-guide on the server-side, when you wish to pre-geocode static addresses or coordinates prior to using the response values on a Google Map. Storing those values is assumed.
It is common to perform some form of post-response/post-storage processing on those values, just like the ordering by distance that you describe, to fit whatever use case is needed to populate your map with the appropriate data. I understand you want to be careful to remain within the TOS, but what you describe sounds pretty standard.
I am using Google Maps API v3 Distance. It has worked well for the majority of the addresses in my database. However, it seems like some addresses just aren't available in Google Maps, and it seems to pick the closest street address match which could be way off. I would expect Google Maps in this case to provide an answer based on city and zip. Does anyone have a solution? I've thought of double checking mathematically by geocode and checking Yahoo maps(or other sites) for the ones that are way off but that adds processing time and is not a very elegant solution. There must be some setting I'm missing or other such work around.
Thanks!
BTW shout out to the new Json Serializer! Well it was new to me anyways.
How are you formatting the address you are sending ?
I've used the Google Maps API to do some reverse geocoding and if a street could not be found (due to a typo or what have you) Google would return the lat lng for the historic town center.
I structured addresses as Country, city cityzip, street nr.
You should use the location_type of the geometry object to determine what accuracy was returned. I suggest checking to see if the returned resulsts indicate whether a result is anything other than ROOFTOP or RANGE_INTERPOLATED.
