Thank you very much for the opportunity to present the Mapping USA. I'm Uili, I'm the creator and maintainer of Trisemcha. So, to those that does not know what Trisemcha is,

it's a validation tool for opposite maps. So, you can filter the changesets using a lot of options and and yes, with that, you can find the changesets that interest you. You can also save the filters and have here your list of

your filters that interest you. And yes, you can visualize the features directly on the browser. You can see and like inspect each feature that was created,

modified or deleted on the changesets. You can interact with it, see the tags, the metadata and also see the comments,

post comments to the changesets, some information about the user as well. And also, we have some flagged features that we list here on the tab. Also, you can see just

blue tags that are some information. We run a lot of checks on the changesets, on the features, on the user as well, and try to identify some possible problems with the changesets. So,

yes, you can also mark the changesets as good or bad so others can see if a changeset was already checked, checked, checked. And yes, the same child is used by the same community, by Mapbox and by other companies as well.

And the URL is osemcha.org. So, on the recent months, we had a lot of developments on osemcha. We have some new features. And yes, I can present here some of those new features.

We are now registering a lot more information about the changesets. So, recently, some edge tools like ID and Rapid started adding some additional metadata to the changesets. Like, for example, the changesets count,

that is the number of changesets that the user has made until the time that they created that changeset. Also, hashtags, the hosts, that is the website that was hosting Rapid or ID,

and other information like the locale. So, we started registering all the metadata available to the changeset and then you can filter using any of that information. So, if you don't find a specific field on the form,

you can use the other metadata and, for example, to the numeric fields, we have the double underscore max, the double underscore min, to set range of changesets count that is useful to find changesets from less experienced users

or medium or very expensive users. Also, like, for example, the locale, the hashtags, we have the task-risk option that filters any value of that tag

and also the host, for example, to find all the changesets made on the OSMUS task manager. We also start registering the number of comments of each changeset so you can set that threshold, that range of comments and, yes, changesets with a high number of comments

indicates that there is some discussion and, like, some possible problem on that changeset. The changeset list has improved the view. On SMCha, we have the trust users list and the watch list.

The first one is, like, users that you trust and, possibly, you don't want to review the changesets because you trust them and the watch list that is, like, some users that you saw some problems on the changesets and, yes, you can give more attention.

So we show that information with the star to the trust user and that red icon to the watchlisted user and also the number of comments that we see here, the user that has reviewed the changeset usually.

Also, we have an integration between MapRullet and SMCha. So as we check, we have some checks in the features, we can set a MapRullet challenge to some flag

and then all the features that are flagged because of that specific flag are uploaded to MapRullet and then people can review it using MapRullet. So you can, if you have some idea of a new flag,

we can, like, add those flags to SMCha and then also configure the integration to MapRullet. We improved the tag chains. Now, besides the name of the tag, the tag key, we've showed the value of the tag.

So you can see here, like, what was the shortening value that were added or the change on the values or the deleted tag value. We have some new tabs,

a list of features that had some change on the geometry. And it's separated by type. Also, the other features, like created, deleted, modified. Here, you can also, like, open all or close all

or also navigate using the tab button on your keyboard. Like, you just press tab and it goes from one feature to the other. The handling is a bit slow now, but yes, normally it's good.

Yes, so thank you very much. You can contact me on Twitter by email or on GitHub and also thanks Mapbox for the support development of SMCha or Josias. So thank you very much.
