Welcome to OSM! All footprints you mapped here represent buildings, though they could be more accurate. Map the footprint smaller than or equal to the size of the roof, and press q to square the footprints after tagging. Please keep this feedback in mind when contributing in future.

Welcome to OSM and 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 in so that you can see the outline of the building and mark the corners carefully. 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.

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 by hand. 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 that may occur. In JOSM use the [buildingstools plugin](osm.wiki/JOSM/Plugins/BuildingsTools). In ID you must draw the shape accurately enough else shapes will not completely square. This [video about squaring features in ID](https://youtu.be/Xs5wX592E1o) has more information and a demo.

Hello, you did a good job appropriately deleting the footprints in the NE, however the building footprints you added are not as accurate as they could be, and you even reduced the accuracy of an existing footprint here. This is mostly becasue you're including the Walls of buildings visible in the imagery as its taken from the West.

When mapping with imagery captured at an angle, please position features where they are at ground level. You can map the outline of the roof and then reposition the building to the base of the walls. I recommend you watch this [video about mapping dense urban areas](https://youtu.be/JAPiGntG6fs) and read this [written guide](osm.wiki/Roof_modelling#Typical_errors_in_the_interpretation_of_roof_geometry_from_aerial_images).

Hello, you are generally identifying buildings in the imagery, but please take care when mapping them.

Square the corners when appropriate with `q`.

Please do not connect the corners of buildings to other buildings or features such as highways or residential areas. In the iD Editor, hold down the `Alt` key to prevent your cursor from snapping to existing data and accidentally creating shared(grey) nodes. This [video about connected nodes](https://youtu.be/ltn1VOiq5_0) has more information and a guide.

I think the northern most footprint here represents two buildings. Overall the buildings you mapped are aqurate but please exclude the shadow they cast from their size.

Good job improving upon your interpretation, by recognising that you had mapped two buildings with one footprint. You knew the history of this feature since you mapped it, but just so you know, whenever working with other people's edits you should generally modify them. Objects should only be deleted if they do not exist. Thank you for your contribution.

Welcome to OSM. Generally you identified buildings here, but you mapped two pairs of buildings that share common nodes. Please consider the roof shape and shadows of buildings to determine where one building ends and another begins. If you cannot determine, then it's safer to assume they're seperate.

Please do not connect the corners of buildings to other buildings or features such as highways or residential areas. In the iD Editor, hold down the `Alt` key to prevent your cursor from snapping to existing data and accidentally creating shared(grey) nodes.

Hello, the vast majority if not all these footprints represent buildings. They'd be even more accurate if they were generally smaller. Exclude the shadow a buildings casts on the ground from its footprint. Mapping footprints slightly smaller than pitched roofs accounts for the overhang and helps prevent data issues in dense areas.

The southern footpritns did not represent buildings. There's something there in the north, I think it might be some remains of a building that used to be there. I deleted them all. Did you upload these seperately on purpose? Please keep this feedback in mind when contributing in future. Thank you for your contribution.

Hi I'm here to review your changeset.

First, the vast majority if not all of these buildings represent buildings.

Some of the buildings could have been more accurately mapped: exclude the shadow a building casts on the ground when using the roof to draw its footprint. You didn't square the footpritns `q`, though on some buildings this was really no issue at all since you placed the nodes accurately so I only had to square them.

Hello, the round buildings you mapped here are in fact rectangular features. I'm curious... why did you manually draw/modify them?

Basically all the footprints you added represent buildings, however they are generally larger than they appear in imagery, becasue the shadow has been included in the size of the footprint.

A general comment about mapping buildings;

When mapping buildings, please trace the shape accurately. Accurate building footpritns aid population estimates and prevent issues like data overlaps. Zoom in so that you can see the outline of the building and mark the corners carefully. 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.

Thank you for your contribution!

I mapped a few of these in https://osmcha.org/changesets/172236104 to show you what a good one looks like.

Hello Myles, You identified and mostly mapped individual buildings and generally tagged them correctly.

The footprints you added could be more accurate please watch this short video about mapping building footprints in ID. https://youtu.be/Xs5wX592E1o
