Hello. Thanks for mapping.
Please, when you map buildings, please map them correct over the whole roofline and position them correctly as well.
Did you copy-paste many buildings ? If so, check that they cover the correct image.
Best regards

Hello. Thanks for mapping on this project.
A remark about recognizing a building or a walled plot or courtyard.
You mapped a few courtyards/walled plots as a building.
Sometimes difficult to recognize.
When an object shows walls, with on both sides a shadow (on the inside of what might be a building) It is mostly just a walled yard or plot.
Buildings don't show a shadow on the sunny side of a roof.
There is often a courtyard inside the building. You can then create a multipolygon to show the courtyard.

Hello. Thanks for mapping.
Please map more accurate, square the buildings and be sure all buildings are mapped.
Best regards and keep mapping

Please map each building individually without connecting the nodes.
(see the instructions)

Hello. Tanks for mapping.
Don't tag highways as a hedge.
Hedges are clearly visible as a dark line. Highway are visible as a light trace.

Hello. Thanks for mapping.
Please leave a gap in a fence where a road is crossing it. Now it blocks a route when you use GPS nav systems.

Hello. Thanks for mapping.
A few remarks.
Check the highway wiki to get an idea how to tag traces of paths/roads in this area
osm.wiki/Highway_Tag_Africa?source=post_page---------------------------
A footway is a dedicated path within towns or parks. Not here.
Tracks are also not to be tagged in this rural area. (path or unclassified highway is better)
Best regards and keep mapping/

Hello. Thanks for mapping.
You added fences without proof of a fence. They can be identified as a (intermitted) black line, often next to a path.)
Highways her are mostly paths, ( <2 mtr) or unclassified highways. Read the highway classification wiki how to tag tracks, roads etc.
Check this wiki how to tag highways in this area

Hello. Thanks for mapping.
Please pay more attention to accurate mapping. You overlooked also the reported issues which had to be solved before you upload your mappings. 87 buildings out of 237 mapped buildings are not squared.

Hello. Thanks for mapping.
How did you manage to map already mapped buildings on this task ?
Were mapped march 20 2025
29 buildings !

Hello. Thanks for mapping.
About High buildings.
You've mapped several times a building as 3 separate buildings.2 x different levels as 2 buildings
1 x a siding as 1 building.
Check this guide to see how these buildings ought to be mapped.

Hello, Thanks for mapping.
Please do not change a correct tagged highway (residential) into route=residential.
Please map buildings as 1 mapping.
Don't you use the building tool ? With this tool you draw perfect rectangular buildings.
You crossed a highway with a few buildings you mapped.
Don't you use the inline validation tool ? It warns you about these errors.
best regards

We welcome you as a new mapper.
Thanks for your contribution to this project.
This changeset is reviewed by a Global Validator to check that the tasks have been mapped in accordance with the quality standards of HOTOSM.
We cannot expect from a new mapper that he/she delivers high-quality mappings from the start, so we offer some guidance.
Please pay attention to the next summarized issues. (see attached document with examples for more info)
-------------------------------------------------------------
Issues found on your mappings

A: Inaccurate mapping.

B: Overlapping buildings. Don't add a layer to hide an error !
D: Connecting Nodes to other features.

E: Buildings not squared.

G: Included the shadow of the building.

High building(s) incorrect mapped. See par 20 chapter About Buildings

Explanation can be found in this document what might be helpful to strengthen your mapping skills

Hello. Thanks for mapping.
A remark.
When you map a building, please map a rectangular from the first till the last node. Here you mapped just 2 lines (3 nodes) and connected them to another partial mapping.
This is not correct mapped.
Just remove the other mapped part and map a complete new building.
See this webpage
osm.org/way/1376320016/history#map=19/34.327720/62.200135
and this one
osm.org/way/1376271105/history

Please do not connect nodes of adjacent buildings to each other.
Keep the ctr key down while mapping near another mapped building.
Map them as separate buildings

Best regards

Hi again
Take a look at this webpage to see which adjustments I had to make.
Red lined buildings were mapped by you and removed by me.

Hello. Thanks for mapping.
I noticed that you map buildings in a very weird way. Try to image that most buildings are rectangular and exists of lower buildings, often with rooftops and courtyards. Often it is a building block. Difficult to recognize. Black lines are shadows. Large shadows from high buildings

This message I send to mappers who are struggling with recognizing the building structure.

Check that walled courtyards or walled plots are not mapped as a building.
Don't forget to square each rectangular building as well.

About mapping of high buildings. They show a large shadow.
Difficult area to map.
Big building blocks with several stories and courtyards

Check here how high buildings ought to be mapped.

https://docs.google.com/document/d/1z7uDwYm4oNmlexHIhJxGCjPpNhCQAgRia5aEJr_4MwM/edit?usp=sharing

Many tall buildings have a small building, a superstructure, lift building or something similar on the roof. They give a shadow as well, so do not map them as a separate building, just map the roof lines of the complete building, and move the whole to the footprint. You can often see it in the shadow.

Best regards and keep mapping

Hello.
Thanks for mapping.
A short note. Please do not add a layer to a building to hide an error !
Just fix it.
