| 166859058 | Footprints quite well mapped but could be more accurate. Please read my project comment to see how to modify features after tagging and squaring them. Thanks for your contribution.

|
| 166858219 | These footprints are both valid and quite accurate. The northern one is very well mapped.
|
|
| 168402713 | Looks like you're generally identifying buildings in the imagery and you improved some of the footpritns here, however some are inaccurate. for example the one in the SE. I previously improved the accuracy of this footprint but the one you replaced it with is oversized.
|
|
| 166859691 | You correctly identified buildings in imagery but generally mapped them oversized. See my project comment. Please do not add layer tags to 'resolve' overlapping features issues caused by inaccurate geometry.
|
|
| 166859603 | I flagged some footprints where you mapped only one side/part of the roof. Bear in mind that you are looking from above so you will see roofs. Depending on the orientation of the building and its roofshape it may have light and dark areas. Identify from where the scene is lit before mapping to use light and shadow to aid your interpretation. In ESRI the shadows are cast NW. Please include the project hashtags like hotosm-project-xxxxx as this helps track the contributions made to the project.

| 166860352 | The vast majority of footprints are accurate here, but the round ones are not appropriately shaped. Generally these footprtins are inaccurate becasue you have included the building's shadow in its footprint. Accurate footpritns lead to better population estimates and prevent data overlap issues. Building footprints can generally be mapped slightly smaller than the roofs you see in imagery.

| 168403013 | You apear to have generally identified buildings in imagery but you have not mapped them accurately. Please focus on making quality contributions that others can build upon. You generaed shared nodes between a building and highway hold alt to prevent your cursor from snapping to exisitng data. Please keep this feedback in mind when contributing in future. Thank you for your contribution. If you want to experience the OSM community or to get timely feedback from other mappers; I recommend that you attend a mapathon.

| 168403391 | The vast majority of footpritns in the North here are temporal yurts and should not be mapped as they will likely not be there for long.
|
|
| 168404148 | The square footprints are invalid and inaccurate. You correctly identified round buildings in imagery but they are generally oversized; roofs tend to overhang walls somewhat. Good job modifying the highway to prevent it from overlapping the buildings you added.
|
|
| 168403209 | footprints correctly identified and well mapped, but they should not share nodes with landuse areas nor highways. Hold alt to prevent your cursor from snapping to existing data. See my resolution in Changeset: 168815108
|
|
| 168403009 | You correctly identified buildings in the imagery but they are generally slightly oversized. Roofs that you see in aerial imagery tend to overhang the walls of buildings somewhat.
|
|
| 164324949 | A generall improvement of map data but some footpritns are still not as accurate as the imagery allows them to be. You correctly deleted footpritns which represented temporal yurts.
|
|
| 164325125 | You improved the accuracy of all building footprints here and added valid and accurate footprints. Well done! Thank you for your contribution.

|
|
| 168403533 | A valid but oversized footprint. Please see my project comment about accurate footprint mapping. See Changeset: 168814513 for how I mapped it.
|
|
| 166858686 | Looks like you improved these footprints by squaring them but they share nodes with other features. Please watch the missing maps beginer mistakes videos for demos on how to resolve such issues.
|
|
| 168402809 | You correctly identified round buildings from the correct imagery source, however they are generally oversized. Please see my project comments to see how to scale features to make them an accurate size.

|
| 164178720 | Well done you imprvoed the accuracy of these footprints by appropriately squaring them. They could still be more accurate. Generally the footprint can be a bit smaller than the roof.
|
|
| 144096320 | Good changeset comment, size and theme. In future where practicable please state the sources of the information. Aerial imagery was probably used to identify the roads and align map them but the speed limit signs are not directly visible in the aerial imagery. It would be better to state e.g. source=survey if you have seen the signs yourself or perhaps add a link to licence compatible street level imagery where the signs are directly visible. This makes it easier to verify the information you're uploading and make it more likely to stick around on OSM. Thanks you for your contribution hope this helps.

| 168485385 | I flagged a few footprints that look like they envelope multiple buildings. I mapped some of these in chageset 168805126 so you can see my interpretation. ---Take care to not include the walls of buildings in the size and shape of the footprint in Bing the NE walls of some buildings are visible. aquire the footprint by tracing the roof and move it to the base of the buildings. It's generally more accurate to map footprints slightly smaller than the roof of buildings where it likley extends beyond the walls. Hope this helpful.
