Hi, the footprints you added here are generally valid and appropriately shaped, however they could be more accurate.

Thank you for your contribution!

When mapping buildings, please trace the shape accurately. Accurate building footpritns aid population estimates and prevent issues like data overlaps. Zoom out to obtain the orientation and shape, then zoom in so that you can accurately draw the footprint. Exclude shadows and yards when tracing the footprint. Keep in mind that you are looking at the [roofs of buildings](roof:shape=*#Roof_shape), but mapping their footprints. Depending on how the scene is lit, pitched roofs may have light and dark sections that belong to one building. Generally pitched roofs overhang the walls of a building, so a footprint slightly smaller than the roof is accurate. You can scale selected features in ID with `shift+(-/+)`, or JOSM with `ctrl.+alt+Lclick & drag`. Take care to make contributions that others can build upon.

Keep on mapping!

also don't fret about deleting the POI; I restored it in https://osmcha.org/changesets/175943947

Hi, the footprints you mapped here envelop multiple buildings. There are barriers around clusters of buildings here.

Each footprint should represent a building. Please watch [this video about imagery interpretation](https://www.youtube.com/watch?v=CJ-vUwtS3A8). Sometimes buildings may appear to share a common wall, but this is sometimes an illusion; only map them with shared nodes if you have reason to believe that they really do touch.

Please keep this feedback in mind when contributing in future. Thank you for your contribution. If you want to experience the OSM community or to get timely feedback from other mappers; I recommend that you attend a mapathon. You can find events here https://osmcal.org/

Hi, the vast majority of footprints here are valid, though could be more accurate. good going mapping the semicircle here, but it looks to me that it represents a yard and not a building.

After tracing and tagging features which are likely square or round, please remember to square their corners `q`, or circularise them `o`, because it is almost impossible and time consuming to draw shapes so percisely manually. Buildings with metal or pitched roofs tend to have square corners; round buildings are identifiable by the distinctive cresent shaped shadow they cast. Unless the building is clearly a different shape then it's best to assume that it should be rounded or its corners should be squared. In the ID Editor, you can `right click` for access to editing functions. Since roofs tend to overhang walls trace the initial shape slightly smaller to allow a buffer for any change in size which may occur. In JOSM use the [buildingstools plugin](osm.wiki/JOSM/Plugins/BuildingsTools). In ID you must draw the shape accurately enough if you want every corner to be squared. This [video about squaring features in ID](https://youtu.be/Xs5wX592E1o) has more information and a demo.

Hi, it's good that you're taking care to preserve the history, however personally I would have deleted or reverted footprints this inaccurate rather than replacing their geometry, becasue this to me pretty much falls into mixing the history. You can check the history of elements with ctrl+h, before deleting to be sure there's no additional data in previous versions.

Thanks for reconfiguring and aligning the highways here too.

I do not think this footprint represents a building. There is perhaps a building just a few meters East of it.

these footpritns represent buildings. They are accurate, the southern one could perhaps be a tiny bit smaller, but this is minor.

You correctly resolved a duplicate footprint here, though Ithink the southern footprint should have been squared. I think the footprints you added represent buildings and that the NW one should be round.

hi, the right footprint represents a building, the left represents a yard. hope this helps.

Hi, all but one of the footprints you added here likely represent buildings in the imagery, but they could be more accurate.

Some of these buildings are oversized, and some are shaped like pacman. I see the dark spots it seems like you were trying to avoid, but just know that the outline of building=yes areas typically represent a buildings exterior wall(s), so by mapping them like pacman you're implying that the wall is shaped like that.

Therefore even if a section of the wall was missing, it'd still be more accurate to just map it as a circle. Most likely the dark spot is just a shadow, or a missing section of the roof. Perhaps it is a shadow, becasue several such features have a dark spot there on the same side.

The top footprint looks like it represents a building, but I'm not sure about the bottom one, perhaps it's multiple small adjacent ones that look like a complex shape. thanks for carefully tracing what you saw in the imagery but just know that sometimes there may be things which obscure the true shape of a feature.
