The Northern footprint represents a building the Southern one does not. The Northern footprint is oversized becasue part of the building's shadow was included in its shape. Also jsut becasue there are fields available in the tagging preset doesn't mean you have to fill them all in. You tagged the flagged footprint as having 0 levels which would indicate it either isn't a building or it has collapsed. Building=yes is sufficient; it is rare/more difficult to extract more information from aerial imagery alone. Only add extra tags if you're confident that the information is correct. I deleted the southern footprint and modified the Northern one. Please keep this feedback in mind when contributing in future. Thank you for your contribution.

The footprint you added here does not represent a building but rather a barrier like a fence or wall. Look at the way the shadows are cast. They're cast from both sides. cross reference Mapbox for a different view. I deleted this footprint. Please keep this feedback in mind when contributing in future. Thank you for your contribution.

You identified a building in the imagery. The footprint is valid and accurate but should be squared. please watch this video for a demonstration https://youtu.be/Xs5wX592E1o?feature=shared --- It should then be moved NE to the base of the building. Here the Northern walls of buildings are visible due to the angle the imagery was taken at. See my project comment about using a secondary source to aid your interpretation. You're looking from above and using the roofs to obtain the building's shape but mapping the footprint. See how I mapped it in Changeset: 169080379 yes it looks a little weird but that footprint is now in an accurate position. Please keep this feedback in mind when contributing in future.

Hi Anabel, You identified buildings in the imagery, well done. These footpritns however are not accurate due to their size and not being squared.

You correctly idenitified and deleted two invalid footpritns in the SE of this changeset. I agree that they did not represent buildings.

Overall you've improved the accuracy of the footprints in this changeset. Generally footprint size has been reduced so they no longer envelope the shadows cast by buildings. Beware that objects can shade themselves i.e. there are dark and light parts of roofs depending on their shape and sometimes the (shaded) wall of a building may be visible if the imagery is taken at an angle.--- you appropiately changed the shape of footprints from square to round. You did this by deleting and remapping the footprints but you can actually just select square buildings you think are round and press (o) to circularise them, then move (m) and scale [shift+(-/+)] them to make them accurate instead of mapping from scratch. The circularise function only requires a minimum of 3 nodes. You deleted some valid footprints here. I previously mapped some of these becasue they are likely buildings under construction. Thanks for your contribution.

You correctly replaced some buildings you previously mapped as round with square ones. The shape is more accurate but what you are looking at there is the skeleton/walls of a building under construction. Since it has no roof yet the internal walls may make it seem like multiple buildings but it should be mapped with a single footprint. again cross referencing (older) Bing may help as you migh spot some buildings which were under construction there and have been completed by the capture date of ESRI. Seeing some confirmed examples will help you better interpret the imagery.

It seems that most footprints you mapped here are valid (visible in imagery) and have been appropriately squared but a significant proportion represent yards. I see no evidence that you used a secondary imagery source; this would I think significantly improve the quality of your mapping especially in this project. Sometimes it is difficult to tell what is a building in this project becasue some have dark roofs and look very similar to yards but cross referencing another imagery source can help A LOT. I wrote a proejct comment detailing how to do this. Please keep this feedback in mind when contributing in future. Thank you for your contribution.

Hi Dou g Wilson, the footprints you mapped here are generally valid (exist in imagery), accurate and appropriately squared. I flagged the most likely candidates for footprints wich envelope multiple buildings. Though it can be difficult to tell with some of the buildings in this area, use roof colour, orientation, and shadow to determine where one building ends and another begins. Overall this is a high quality contribution; thank you. If you want to experience the OSM community or to get timely feedback from other mappers; I recommend that you attend a mapathon.

Hi begrian, you correctly identified buildings in the imagery. Most though not all footprints here have been appropriately squared. The footprints you mapped are generally oversized and some (flagged) likely envelope multiple buildings; use roof colour and shadows to determine building size, shape and where one building ends and another begins. Use shift+(-/+) to scale selected features after tagging and shaping them. --- Landuse and footpritns should not share common nodes.

Hi Esabela, the footprints I flagged envelope multiple buildings. Every footprint should represent an individual building. Use shadows, roof colour and a secondary imagery source to idenitfy where one building ends and another begins.
