You identified and mapped buildings in the imagery here. Consider how people on the ground will travel. The footprint I flagged is clearly oversized, because it overlaps a highway visible in the imagery meaning they would overlap. You're looking at the roofs but mapping the footprints of buildings. Hope this helps. Thank you for your contribution.

All footprints represent buildings in imagery. I think the footprint I flagged likely envelopes 2 buildings and that the Western most footprint is oversized. Roofs tend to overhang footprins somewhat, so mapping the footprints slightly smaller is considered accurate. Sometimes the roof is extended to provide shade, or highways go underneath them in the imagery. This can also help when mapping in dense areas to not create data overlaps. Hope this helps. Thank you for your contributions.

Hi, all of the footprints you added here represent buildings in the imagery and they have been appropriately squared. Some could be more accurately positioned (m), oriented (r) and sized (shift+(-/+). Please remember to tag the features you map. Why did you use bing to map here? The custom source for the project has a much greater resolution and is more recent. Your mapping should reflect the primary source of a project. Thank you for your contribution.

Hi, you idenitfied buildings in imagery but they are not accrately mapped. Do not add layer tags to hide 'resolve' overlapping data issues who's root cause is inaccurate geometry. I recommend watching the new mapper mistakes videos on this page https://www.youtube.com/@TheMissingMaps ---Please keep this feedback in mind when contributing in future.

Hi, do not add layer tags to features to hide overlap issues when the root cause is inaccurate geometry. Modify the geometry so that data does not overlap.

The features I flagged have unnecessarily been mapped as multipolygons. Multipolygons are used to define more complex scenarios, using them excessively makes the data more difficult to work with.

Hi, Emma. If you do not tag the features you map then the data base won't know what the geometries you digitised represent. I applied tags to buildings you mapped. The features I flagged likely envelope multiple buildings. consider what the footprints under the roofs look like. Please keep this feedback in mind when contributing in future.

hi, you generally are identifying roofs in the imagery. I flagged a few features which likely envelope multiple buildings. Consider what the most likely footprint shapes under the roofs are. Sometimes cross-referencing a secondary source can help, just remember to map using the primary source. --- the Northern most building shares points with an adjacent building but a path can be seen between them in the imagery.

Hi. It looks like you aligned highways to imagery well and correctly identified steps in the imagery on some occasions. The feature I flagged looks like it has sections of steps and some flat/ramp sections.

Regarding your comment about deletion; it probably was possible to seperate the features which shared nodes by disconnecting them. You did well to try to preserve the tags and inform me of the deletion. I have restored the history of the school buildings and pitches deleted in this changeset.

Why did you tag the ways flagged as highway= corridor and indoor=yes. I can see a car on that highway in the imagery. Please keep this feedback in mind when contributing in future.

You're welcome; thank you for responding!

Some of the footprints you added here are okay, but there are many others where it appears that you mapped them inaccurately becasue existing data was in the way. You should modify the existing data if it is inaccurate to allow allow for accurate mapping. You can use the w or alt+w shortcuts to toggle map data and get a better view of the underlying imagery to make more informed decisions regarding existing data.

Generally it looks to me like you're identifying buildings in imagery and taking care to map the features you add accurately, and you're modifying features instead of deleting and re mapping them. Thank you very much for that. The footprint I flagged likely does not represent a building but rather a part of the roof of the building to its East. Consider that you are looking from above at the roofs of buildings but trying to map the footprint (which is at ground level). The footprint doesn't necessarily completely match the shape of roofs try to map what is the most likely footprint shape e.g. there could be some parts of the roof missing, or they might overhang the footprint. Sometimes the roof is corroded making it appear as a different building. I hope this helps.

Hi, you generally identified buildings in imagery. The footprints I flagged envelope multiple buildings. Take care to map one footprint per building.

Hi, consider that you are looking from above but mapping building footprints. I flagged a few features where it looks like you mapped sections of roof which likely belong to one building.

You're tagging these as houses; have you surveyed them? If so, I'd be great if you could include the source "survey" in your changeset tags.

Consider that you are looking from above when viewing aerial imagery, but mapping building footprints. The roof shape is not necessarily the same as the footprint. It's generally accurate to map footprints slightly smapper than the roof; this also prevents data issues like overlaps etc. Please keep this feedback in mind when contributing in future.
