| 175468939 | Hi, just to follow up on some of my previous comments, thank you for considering the scope of features you uploaded in this changeset and submitting a comment relevant to the features you mapped.

| 175460003 | Hi, nice to see you mapping again. The suqare buildings look valid to me, though they are slightly oversized. Consider that you are looking at roofs but mapping footprints. Mapping slightly smaller than the roof tends to be more accurate. I can tell that you are carefully scanning the imagery, which I really appreciate, but the circular footprints you mapped do not represent buildings; rather piles of (most likely) building materials. Contrary to the instructions for this project ESRI is more recent in this area and you can see some of the built buildings in it. Such piles of material are common at construction sites, it may help your interpretation if you saw one from the ground level or an oblique angle, perhaps even go and see one for yourself. Please keep this feedback in mind when contributing in future. Thank you for your contribution.

| 171346952 | Hi, Shel_Sri you're welcome and thanks for writing! To answer your first question, no it is not more recent, but I analyse imagery more holistically than just the capture date. I likely cross-referenced some other useful imageries I found in the wayback. For the second, I am going to refer you to this great diary about using the sources I did here. @Deane%20Kensok/diary/397014 also I have provided some instructions on tasks I've invalidated in #32710 with the offset to use etc. |

| 173666526 | Hello, you did not position the footpritns you mapped here at the base of buildings resulting in some being as far as a dozen meters out of alignment. |
|
| 173722573 | hello, you mapped a building's wall as a footprint here. |
|
| 101637574 | It appears to me that you mapped the outline of a school as a school building. Please use ameity=school for this purpose and map the individual buildings within the area of the school. please consult amenity=school#Single_school_on_one_site |
|
| 173705101 | Hi, you duplicated building data here. In ID It's better to modify data if you can determine which feature it represents, rather than mapping it anew.
|
|
| 173603257 | Hello, When mapping buildings, please trace the shape accurately. Accurate building footpritns aid population estimates and prevent issues like data overlaps. Zoom out to obtain the orientation and shape, then zoom in so that you can accurately draw the footprint. 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.

| 173782710 | Hi, this looks like land likely used for agriculture. Scrub tends to be a natural (unmaintained) landcover. Here the trees are planted in a regular grid. Please keep this feedback in mind when contributing in future. Thank you for your contribution.

| 173603334 | Hello, 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 manually. 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 which may occur. In JOSM use the [buildingstools plugin](osm.wiki/JOSM/Plugins/BuildingsTools). In ID you must draw the shape accurately enough if you want every corner to be squared. This [video about squaring features in ID](https://youtu.be/Xs5wX592E1o) has more information and a demo. |

| 174421856 | Hello, though you made some mistakes, I can certainly see improvement in your mapping e.g. you identified and mapped 3 valid buildings in the North. --- Unlike the previous project you were contributing to barriers are beyond the scope of this one, so you are not required to map them. The things you mapped as hedges are in fact trees. You changed a tag of a multipolygon to building=yes resulting in overlapping buildings and highways on the map. If you're unsure about feature tagging consult osm.wiki/Map_features . You may be able to see how that looks on the map by visiting changeset/174435612#map=18/6.941923/126.258137 . You can see the changes I made to your mapping in https://osmcha.org/changesets/174435612 . Watch this short video about mapping buildings https://www.youtube.com/watch?v=oNJiIL_qTIM . --- Please keep this feedback in mind when contributing in future. Thank you for your contribution.

| 173642493 | And another thing I just noticed. comment hashtags are used for tracking statistics you're free to use whatever hashtags you like in addition to those for an organised project, but you can also just write your changeset comment in plain text. Thank you for writing one!

| 173796255 | I think you appropriately deleted a building footprint which enveloped multiple buildings here. Thank you for your contribution.

| 173642493 | Hi, my intention is to help you improve your understanding. The outer buildings look okay here but I think the middle one should in fact be mapped as two. Not all buildings are square or round, but consider simpler options before representing a building with such a complex shape. See how I mapped this in https://osmcha.org/changesets/174402273 Thank you for contributing!

|
| 173794462 | Hi the NE building is accurately shaped but not positioned quite right. Map the individual buildings in compounds and not the entire thing. Why did you apply the building=house tags here? You can see how I mapped the eastern part in https://osmcha.org/changesets/174402273

|
| 174390305 | Welcome to OSM and thank you for your contribution! None of the footprints you've added thus far represent buildings, so I've reverted your changesets. Each footprint should represent a building. Please watch [this video about imagery interpretation](https://www.youtube.com/watch?v=CJ-vUwtS3A8). Sometimes buildings may appear to share a common wall, but this is sometimes an illusion; only map them with shared nodes if you have reason to believe that they really do touch.

|
| 174323063 | Hello, it looks like you identified highways in the imagery.
|
|
| 174322187 | Hello, my interpretation is to improve your understanding. Many of these footprints do not represent buildings and you duplicated existing data. Refer to osm.wiki/Good_practice#One_feature,_one_OSM_element Please keep this feedback in mind when contributing in future. Thank you for your contribution.
