How to add a new geocoder?

[Wegge]

I've set up a copy of the script to post a random square kilometer of Denmark. The reverse geocoding for Denmark is very coarse, so I'd like to use a local API instead, to get a better resolution. Where in the code would be a good place to add this in a way that will make it suitable for addition?

So ærialbot is by default just using Twitter's own reverse geocoding API – the request is sent in the Tweeter.get_location function (line 696 as of 50ec0b3) which returns a tuple of (full_name, country). You could supposedly subclass the Tweeter class and reimplement Tweeter.get_location to query DAWA instead of Twitter, but it might be simpler to replace the function call in line 892 with your DAWA querying logic.

(And make sure to provide me with a link to your bot if you don't mind – I've spent many childhood summers in Denmark, so I'm definitely interested!)

I've hacked something together, that seem to work. I'll play around with it a bit more, and see if I can generalize it to an option in the inifile that allows for selection between different geocoders. It's tweeting as https://twitter.com/DanskKvadrat Right now a square kilometer, but I think I might increase the area a bit, to avoid too much farmland.

Sounds good!

Yeah, this was surprising to me too – it's even more farmland in the US. Out of the hundreds of test images I generated for @americasquared, only four or five were of (sub)urban areas.

Closing this issue since your bot has been up and running with your custom reverse geocoder for quite a while. 🙂
