Hi, you identified and mapped some buildings accurately here, however others inappropriately share nodes with others, have not been appropriately shaped or envelope multiple buildings visible in imagery. I flagged some footprints here I think could be better mapped.

Check https://osmcha.org/changesets/171747971 for an example.

Hi, you correctly identified, tagged and squared building footprints. Most are quite accurate but the imagery allows for some to be more so.

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.

You generally identified buildings in the imagery here but they imagery allows their footpritns to be mapped more accurately. Zoom in and out to aid your interpretation and consider the roof shape of the buildings you're mapping.

Hi, you generally correctly identified buildings in the imagery and tagged them correctly, but they could be more accuate. I have some feedback for you so that you can improve your future contributions.

The circular building you added actually envelopes a smaller square one.

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.

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.

Hi, you appropriately adjusted the residential area to prevent overlaps with footprints. I flagged some footprints here I think represnet vegetation. The footprints you mapped are accurate enough, but could be more so if they were generally smaller.

I flagged a highway here which should have been connected to an existing one. It's important to do this becasue routing algorythms require that highways are connected to function. You can see how I connected them here https://osmcha.org/changesets/171713965

You corretly assessed the possibility for a car to use these highways and changed the tagging part way along a highway to reflect this: well done! The highways could be more accurate: enure that the bends in the highwayas are identifiable.

When mapping highways, please trace their shape accurately. Accurate highways aid navigation and prevent issues like data overlaps. Zoom in so that you can see the width of the highway. The lines you trace to represent highways should follow their centre; so add more nodes the more they curve and click at the start and end of straight sections, as a rule of thumb keep the lines you trace within the width of the highway you're mapping. Following tracks or road markings can help.If the highway fans out into several close alternative paths to the same destination then you only need to trace the median or what looks like the most used route. Thank you for your contribution.

All highways you added here look valid accurate and appropriately tagged. Tip: check other imagery sources if the primary one has cloud cover like it does here. Please focus your efforts on highways that link settlements. Thank you for your contribution.

Welcome to OSM! Thank you for submitting a custom changeset comment! Just bear in mind that id you're contributing as part of a project don't strip the hashtags becasue these are used to track proejct stats. You corectly identified highways and assessed their width. You clearly took care when tracing the highways, thanks for that. It looks like you may have slightly confused by the path of the northern highway; this is becasue it crosses a waterway I'd say given the context it's likely accurate enough. You correctly identified a residential area and tagged it correctly; rememeber to add a place= node to mark what kind of settlement it is. Thank you for your contribution.

You spotted highways in imagery. You correctly assessed the width of the western two highways but the eastern one is in fact wide enough for a car evidenced by the tracks on the ground. For the puropses of this project please consider whether the highways you're mapping connect settlements; those which don't are beyond the scope of the project.

Hi, it looks like you mapped these residential areas with a similar workflow to what would be used to map building footprints. This has led to less accurate mapping. We square footprints after tracing them becasue the shape is likely square, however this is not necessarily the case with residential areas. For instance a city block may be accurately mapped as a squared residential area, but these rural settlements likely have more complex residential areas. You can use more than 4 nodes, you know. Consider natural boundaries, the colour of the ground, and how the land is being used when mapping residnetial areas. Thank you for your contribution.

These are highways but please check the width of the highway and check for visible evidence of use by cars when tagging, and consider the context such as the topology of the area; steeper routes are more likely to be paths.
