MapQuest API key issues about elodie HOT 5 CLOSED

Well, the good news is that because MapQuest is an Nominatim instance, it's possible to do a straight replacement of https://github.com/jmathai/elodie/blob/master/elodie/geolocation.py#L102 with:

r = requests.get('https://nominatim.openstreetmap.org/reverse?%s' % urllib.urlencode(params))

(I assume the same is also true for lookup(name) but I've not tried it.)

The bad news is Nominatim's usage policy. Specifically:

• No heavy uses (an absolute maximum of 1 request per second).
• Provide a valid HTTP Referer or User-Agent identifying the application (stock User-Agents as set by http libraries will not do).

Bulk Geocoding

As a general rule, bulk geocoding of larger amounts of data is not encouraged. If you have regular geocoding tasks, please, look into alternatives below. Smaller one-time bulk tasks may be permissible, if these additional rules are followed

• limit your requests to a single thread
• limited to 1 machine only, no distributed scripts (including multiple Amazon EC2 instances or similar)
• Results must be cached on your side. Clients sending repeatedly the same query may be classified as faulty and blocked.

I'm not entirely sure if this app would fall foul of these rules though.

As a mater of fact I'm looking into a cache

It seem to work but need a little cleanup like maybe you would like to set the distance for coordinate lookup reuse currently it's about 3km. And it saves the file to disk everytime an entry is added. Maybe it should not be saved at all? But lets have that discussions in it's own issue. I was planing on working on it a bit more before showing it as I just got i working but as the discussion above mention the need I just wanted to show it.

@edent This link works for me. https://developer.mapquest.com/plan_purchase/steps/business_edition/business_edition_free

Glad that Nominatim can be a drop in replacement. We can make the path configurable. I think this tool tends to fall within their requirements. When doing a mass import the number of calls may be around 1/second but it's also possible to throttle that. Once your initial import is done the remaining usage tends to be much more sparse.

@zingo that is brilliant. I've been wanting to add that in almost the same way you have. I would probably move it to the geolocation module though. I'll create an issue for this and you can open a pull request once you're done :).

@jmathai thanks - the MapQuest site now seems to be working again :-)
