Hey Vivek Dumre,

Thank you for taking your time to review changesets for your open mapping hub's program.

I would recommend you focus on 'New mapper' changesets, especially those with 'Review requested' label.
You can also use the 'Filters' => 'Reasons for Flagging' to get only these changesets, or use the 'Location' filter to get only changesets in a certain area. i.e. it may be useful to look only at the area which is the focus of your open mapping hub, where you have the most experience. Local mapping guidelines elsewhere may differ from what you are used to.

You're welcome to review more experienced mappers' changesets, though try to avoid reviewing multiple by the same user in this case, unless reviewing as bad. Also, some users do not like such 'thank you for mapping' messages as they may appear copy-pasted and do not contain any feedback on how to improve mapping, which may be wasting your and/or the users' time.
Though, your comment otherwise looks fine of course.

In the future, try to link to the objects in question and try to explain how to resolve the issue, please. (at least one or two good examples.)
Here, I don't know what you were refering to. It could be
I.e. The building
https://www.openstreetmap.org/way/156354822/history
is slightly too large, is not rotated correctly, has an extension...
Have since modified both buildings from this changeset. Noteably, it is not the first version of the building outlines and the geometry did not change even slightly -which may happen if I add a building part and square the full object-. See OSMCha preview or
https://overpass-api.de/achavi/?changeset=151514175
There was only a roof building part added and some empty nodes -by accident- which were left over from aligning the POI nodes.
It is unlikely to be relevant to discuss the geometry of the existing building with a mapper who only added a building part or modified the POIs. (besides, building parts are usually only added by experienced users.)

For geometry issues, it is important to mention what imagery you are using. The recommended imagery may differ in other locations than you are used to and layers such as Esri and Esri Clarity are only available in editor applications. They are *not* available from OSMCha.

Sidenote: areas such as this where the sides of buildings are visible in aerial imagery (or where they are on a slope) may have an offset applied to some objects to match their footprint. Also, some street level imagery and GPS traces may have been aligned to existing (old) mapping by the application (or are simply too poor), therefore can not be used to determine the precise location of objects.
This may not be directly useful to you as reviewer but it helps to understand why some objects may be at a (seemingly) incorrect position.

Regards,

Daniel
