OSMCha News - January/2018

Posted by wille on 9 January 2018 in English (English).

It’s a new year and we have some new features in OSMCha!!! Let’s take a look on them:

Save filter UI improved

save filter instructions

Now it’s easier to save a filter! After set your filter parameters, click on the Save button on the top of the screen, give a name to it and press the Confirm Save button. The filter will be saved and applied, so the sidebar will update with the results. If you want to change something in your filter later, repeat those steps. Remember that the filters have a RSS feed. Get the link in your OSMCha user page.

Changeset comments

Changeset comments example

From now on, when we review a changeset in OSMCha, a comment will be posted in the OSM changeset page. That way, we give a feedback to the user and make that information accessible to other Quality Assurance tools. The comments have a predefined message and are posted with your username.

Tag changes summary

tag changes summary

Each changeset now has a summary of tag changes. This makes it easy to identify the modifications made in the features without the need of clicking on them one by one.

We’d love to hear your comments and suggestions. You can do so by participating in our mailing list or open issues on our github repository.

Very good, Wille!

I used to save the url to not lose my filter options ;)

Abraços, Linhares

Great work on this tool, Wille.

This is amazing, thank you Wille!

Awesome, thanks Wille!

Do tag changes affect any of validations? Like, adding many footways and parks may signal this is a Pokemon Go edit.

@Zverik No, the tag changes summary runs in the frontend when the page is rendered, but it’s a good idea to identify some patterns and convert it on alerts.

“[OSM-talk] Automatically generated changeset discussion comments by OSMCha” was started at

Thanks, Mateus!

About the changeset comments… This was supported by some members of the community:

Soon, I’ll improve it to give more options to the users. Right now, if you don’t want that OSMCha post comments to the changesets that you are reviewing, when signing up to OSMCha, don’t give permissions to “modify the map”.

I agree that it could be improved, but I do think that it is a move in a good direction and will encourage especially new users by making them feel part of the community. Some improvements I can think of..

  • Ability to customize the message
  • Not sending a message by default when ‘approving’ a changeset if the flag is not ‘review requested’ or ‘new user’
  • make it more obvious that a message will be sent as a changeset comment when you ‘approve’ a changeset. At least remind people at first that this is happening.

On the OSM server side you should be able to opt out of emails, perhaps this is already possible, but if not it should be.

Thanks for the update! I love using osmcha to catch up on edits in a particular area, although sometimes it doesn’t pull all of them in. Change set comments are a step in the right direction, localization of those would help
