Almost all of these footprints are valid though they could be more accurate. Some are oversized the Western building outlines two buildings.

Both of these buildings are valid and appropriately squared, though could have been a touch smaller.

you improved the acuracy of these buildings, however they could still be more accurate and are generally oversized. It's easier to obtain accurate results by drawing the footprint a little undersized and then scalin it up after squaring. Thanks for modifying most of these footprints instead of deleting them and drawing new ones.

The footprints you added here represent buildings visible in imagery. They could however be more accurate and should have been squared using (q) after tagging. Generally it is easier to obtain accurate results if you undersize the footprints a little then scale them up after squaring: Press ? to see ID editing shortcuts to see how to do this.--- Unless you know that buildings share a common wall then you should not map them with shared nodes hold alt to prevent this.

I think that the highway network here may be over extracted; there's not necessarily a need to map all of these highways. I recommend to map highways by starting with those that have clear evidence of usage and are the widest ones like that which pass by the medical facility, then find the best routes which connect the residential areas/settlements you added. Highways should not share nodes with landuse areas. The highway continuity here is not accurate; 1 way should represent 1 highway and not multiple. I recommend downloading and using the apple paint style to help you see this. Using the measurement tool to measure the width of highways is useful in correctly classifying them.

All buildings valid, vast majority accurate. Appropriate modification of residential areas. Residential areas and highways should not share nodes.

Why did you delete the village node in this changeset? If you come accross nodes like this in the future, even if you cannot see a settlement in the most recent imagery or if they don't have a name, it's best to change the tag to place=locality instead of deleting them outright. This makes it easier to undo the change if needed, to preserve local place names, and to classify the highway network. Here the settlement is clearly visible so deleting it was incorrect regardless. See Changeset: 164356744 for my resolution --- The building footprints are all valid and fairly accurate: the main inaccuracy is their orientation use ctrl.+shift to rotate features and ctrl.+alt to scale them in JOSM.

You caused the multipolygon error, becasue you created a duplicate of a relation which was already there. I deleted the new relation you added to rectify the error. ---The health centre footprint is also not as accurate as it could be I used the building tools plugin, draw nodes and extrude tools to improve it and accounted for off nadir imagery when placing it. --- You correctly resolved a highway/building overlap. Please see Changeset: 164356401 for my resolution.

Thanks for squaring these footprints but when doing this be sure to check the accuracy and validity of footprints for example the Wester most one in this changeset is still significantly larger than it should be.

The some of the footprints you added here are too big in particular the two Eastern most ones. The building you modified is now less accurate I would say that the section you extended the footprint to should instead be mapped as a different footprint.

All but one of these footprints are valid; the one I flagged represents a barrier. The footprints you added here should have been squared.

You added temporal yurts and footprints for buildings which are no longer visible in the more recent ESRI imagery. I encourage using multiple sources to aid your interpretation; just be sure to cross reference the most recent source to see if the features you're adding to the map are still there.

The building footprint should be round (press o after tagging). Please keep this feedback in mind when contributing in future. Thank you for your contribution.
