I also wanted to sat that you identified a building in the imagery and updated the residential area by increasing its accuracy.

Hello, the footpritns you mapped here represent buildings, and have been appropriately tagged and squared, but are larger than the imagery shows them to be.

See how I mapped them in https://osmcha.org/changesets/172227835

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.

Hello, overall you mapped these footprints well, just take care to not include the shadow cast by buildings in their footprints. Thank you for your contribution.

Hello,

The source [survey](source=*#Specific_values) indicates that you have personally seen these buildings at their location. Do not apply it for remote mapping activities like this, unless you have actually been to the place being mapped.

Hello, it looks like you forgot to square a couple of buildings here. If you press `i` and change the unsquare building parameter to 15 degrees ID will do a better job of showing warnings about unsquare building footprints. --- Thank you for your contribution.

The footprints you mapped here are quite accurate they just need a little adjustment to make them as accurate as the imagery allows.

Overall the footpritns you mapped here are very good. The Western footprint includes the shadow cast by the building; take care to exclude these from footprints. Thank you for your contribution.

I think you misinterpreted the imagery a little here and mapped a needlessly complex footprint. I flagged the one I'm refering to.

Hi Tebby,

You identified buildings in the imagery, appropriately tagged and squared them and their overall shapes are generally accurate. The L shaped building is actually just a rectangle but the imagery is taken at an angle. You could make your footprins even more accurate by mapping them smaller than the roof you see in imagery and by excluding the shadow they cast one the ground.

Here's a general comment about mapping building footpritns.

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.

Welcome to OSM! You identified buildings in imagery, tagged them appropriately and generally interpreted the overall shapes of buildings well, however the imagery allows them to be mapped more accurately. Please watch the following two short videos about mapping with the ID editor;

I mapped the T shaped building here as a rectangle. I think the southern part is likely vegetation becasue the shadow is so large in comparison to other buildings.

Hi, all footpritns you mapped are valid and appropriately shaped, thet could be a touch more accurate. Exclude the shadow a building casts on the ground from its footprint and trace slightly smaller than the roof; this accounts for the overhang and gives you a buffer for any change in shape when squaring. Thank you for your contribution.

Hi camilaparrad, welcome to OSM!

You correctly identified buildings in imagery, appropriately squared most footpritns and even identified a building under construction. good job trying to map the actual shapes of buildings.

The footprins could be mapped more accurately if they were generally smaller.

You created a shared node between a building and residential area: hold alt to prevent this.

I recommend you save your contributions say every 15 minutes.

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.

Well I'm glad that you didn't feel it a waste to reply 😉

Perhaps it was not your intention, but I must say that you comment seemed needlessly hostile. You could have instead writen something like 'You could be more efficient with your feedback by doing a and b, becasue x and z'. I'm just sharing my evaluation of your contribution with you and trying to provide useful feedback.

How is it a waste of time to read the comment another contributor has writen to you? I gave you the TLDR in the first paragraph. Even if it takes a few minutes to read a message which improves your future contributions; I'd say that's worth it. Do you not consider improving your skills progress?

Perhaps I could consider cutting parts of the comment on a case by case basis, but I like to provide an explanation for why something should be done, not just state that it should.

Sorry, but "This is not motivating at all." is not very constructive; I can't really apply that in future. Please elaborate. Why isn't it? How could it be made more so?

Regarding your mapping of buildings, I'll Echo my first comment, since I see you mapped them simillarly in a more recent [changeset](changeset/172165368#map=19/-4.993917/21.407769). Generally the building footpritns are somewhat oversized, becasue they either include the shadow a building casts in the footprint, do not account for roof overhang, or extend beyond the roof/shadow visible in the imagery.

Note the direction in which shadows are cast and use them to inform the size of features you map. Footprints of pitched roofs can be mapped smaller than the corners of the roof in imagery to account for overhang, so err' on the smaller side. I recommend viewing street level imagery to get a better undestanding of this; it can help a lot when mapping in dense areas. I think the follwing pages are quite useful roof:shape=* osm.wiki/Roof_modelling

Every footprint you mapped here represents a building, and the majority of them are very accurately mapped. Thank you for your contribution, keep it up!
