Hi Simon,

This is totally awesome! I have been uploading photos recently to Commons and was wondering how I would be able to geotag them efficiently. I tested the tool a while ago and it works as expected.

Here are some suggestions:

1. The coordinates have too much precision. I see 15 decimal places in the tool, which makes the photos geocoded to an accuracy of one-tenth of a nanometer. What is ultimately stored into the File page is 10 decimal places which is still too precise (~10 μm). 5 decimal places (~1 meter accuracy) should be more than enough.

2. For the step of selecting files, it would also help to have the option of specifying a user, defaulting to the OAuth-authenticated user. Usually you would want to geocode files that you yourself uploaded.

Hope this helps!

Hi all,

I'm not totally sure whether this is the correct mailing list, but the
topic is very map related :)

I always figured that there should be a comfortable way for geocoding
existing files on Wikimedia Commons. However, Commons:Geocoding only
mentions tools that somehow generate a {{Location}} string which has
to be inserted manually afterwards.

That's why I tried to tackle this problem. The outcome is the
locator-tool: https://tools.wmflabs.org/locator-tool/

The idea is that you generate/insert a list of media files to geocode.
Afterwards you take file by file, select its location on an
interactive OpenStreetMap-based map. The tool will automatically
generate the {{Location}} string and insert/update the wikitext.

The web application is mostly written in JavaScript using the
AngularJS framework. Only the OAuth and editing stuff requires a slim
backend written in Python/Flask.

Currently it only supports editing {{Location}} templates, but not
{{Object location}}. As far as I understand, the latter is not
returned by the API (action=query, prop=coordinates)? The camera
heading isn't yet editable neither.

Cheers from Austria,
Simon
