some of these footprints are well mapped when looking at bing which was used to map them. I recommend aligningit to ESRI so that features are properly aligned. See my project comment.

The footprints I flagged are oversized and sometimes envelope multiple buildings. Map footprints slightly smaller than the roof since it likely overhangs the walls somewhat.

It's good that you're using multiple sources to aid your interpretation; I recommend that you offset the imagery source before digitising to keep features correctly aligned with one another. In this case the buildings are several meters West of where they should be if they were aligned to ESRI as per the instructions.

The buildings you added here are likley temporal yurts and should not be mapped as they will likely not be there for long. 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 correctly differentiated between round and square buildings. The round building has been appropriately rounded but the square buildings have not been squared and tend to have odd shapes. I recommend watching the missing maps beginer mistakes youtube videos.

The footprint I flagged should be L shaped.

You identified buildings in the imagery and appropriately squared them. The ones I flagged are oversized and sometimes envelope multiple buildings.

I do not believe the features I tagged represent buildings visible in imagery but rather yards or parts of them.

The geometry of the footpritns you mapped here is generally good, though could be a more accurate at times. Check Changeset: 168817115 to see how I mapped some of these features. Keep in mind that pitched roofs tend to overhang the walls of buildings and some include the building's shadow in the footprint. Thank you for your contribution.

The Western Footprint is well mapped more like this in future please. Check Changeset: 168816457 to see how I mapped these buildings.

These footprints are valid but inaccurate. Take care to not include the shadow of a building in its footprint as that makes it oversized. The footprint you deleted is also valid.

Footprints quite well mapped but could be more accurate. Please read my project comment to see how to modify features after tagging and squaring them. Thanks for your contribution.

These footprints are both valid and quite accurate. The northern one is very well mapped.

Looks like you're generally identifying buildings in the imagery and you improved some of the footpritns here, however some are inaccurate. for example the one in the SE. I previously improved the accuracy of this footprint but the one you replaced it with is oversized.

You correctly identified buildings in imagery but generally mapped them oversized. See my project comment. Please do not add layer tags to 'resolve' overlapping features issues caused by inaccurate geometry.

I flagged some footprints where you mapped only one side/part of the roof. Bear in mind that you are looking from above so you will see roofs. Depending on the orientation of the building and its roofshape it may have light and dark areas. Identify from where the scene is lit before mapping to use light and shadow to aid your interpretation. In ESRI the shadows are cast NW. Please include the project hashtags like hotosm-project-xxxxx as this helps track the contributions made to the project.

The vast majority of footprints are accurate here, but the round ones are not appropriately shaped. Generally these footprtins are inaccurate becasue you have included the building's shadow in its footprint. Accurate footpritns lead to better population estimates and prevent data overlap issues. Building footprints can generally be mapped slightly smaller than the roofs you see in imagery.

You apear to have generally identified buildings in imagery but you have not mapped them accurately. Please focus on making quality contributions that others can build upon. You generaed shared nodes between a building and highway hold alt to prevent your cursor from snapping to exisitng data. Please keep this feedback in mind when contributing in future.

The vast majority of footpritns in the North here are temporal yurts and should not be mapped as they will likely not be there for long.

The square footprints are invalid and inaccurate. You correctly identified round buildings in imagery but they are generally oversized; roofs tend to overhang walls somewhat. Good job modifying the highway to prevent it from overlapping the buildings you added.
