Hi, thanks for mapping.

Many buildings you mapped are well done as to their location. However, you can improve by avoiding mapping several buildings as one building. Every building must be traced separately.

You also added layer tags to several buildings that shouldn't be added. Probably because iD Editor incorrectly advised to do so when buildings overlap each other. You should instead move the buildings so that they do not overlap anymore.

Thanks so much for your contribution, Martien, HOT validator.

Hi, thanks for mapping.

You mapped a water reservoir here that does not exist.

Thanks so much for your contribution, Martien, HOT validator.

Hi Mercy, you added level tags to waterways. Maybe to prevent conflict with crossing highways (?)

Level tags are not used for waterways. Better to use layer instead in combination with bridge or culvert. Or ford, without layer.

Btw, the level tag is added to a whole stretch of waterway. Be aware that after removing the tag validation tools will detect incorrect crossings with other features.

Best regards, Martien (HOT Global Validator)

Hi,

Waterways have been added level tags. I guess to prevent conflicts with crossing roads.

The correct way to solve this is adding culvert or bridge combined with the layer tag.

Hi, thanks for mapping and welcome to HOT. You requested a review of your mappings.

You mapped fields as buildings here. This is understandable, sometimes it is hard to distinguish buildings on imagery.

What you can do next time is to look for shadows, open ground, changes in roof color, size of the shape on the imagery.

Zooming in and out can also be helpful.

Thanks so much for your contribution, Martien, HOT validator.

Hi, thanks for mapping and welcome to HOT. You requested a review of your mappings.

The buildings you mapped are well done as to their location. But pay attention to the squareness of the corners. Always draw buildings as square and precise as you can. Then add the Building feature type. And last, right click it and click the square icon.

Then check (again) if the outline of the squared building still matches the outline that you see on the imagery.

Hi, thanks for mapping. You requested a review of your mappings.

Your buildings are well mapped. Good location, square corners and precise outline.

A few buildings are snapped to each other. To improve for next time, please zoom in close enough when tracing to avoid buildings sharing nodes or else overlapping. You can hold the ALT key to prevent this happening.

Thanks and regards, Martien, HOT validator.

Hi, thanks for mapping.

You mapped buildings here, but unfortunately the y are quite off as to their shapes.

The urban area you are in here is very complicated to map. This is best done with the advanced editor JOSM.

My advice is to choose an area that is less crowded with buildings. That way you can build up experience and later on switch to more complicated areas.

Thanks so much for your contribution, Martien, HOT validator.

The buildings you mapped are well done as to their location. But pay attention to the squareness of the corners. Always draw buildings as square and precise as you can. Zoom in as close as possible to see the outline of the buildings, hit each corner of the building carefully. Look for shadows, open ground, changes in roof color and vegetation to differentiate buildings.Then add the Building feature type. And last, right click it and click the square icon.

Hi, thanks for the feedback.

I was not suggesting/saying all the buildings were unsquared. There is one, so therefor my advise.

Checking a few other changesets done by you i see buildings are squared, so i guess i just stumbled upon an exception.

As to the overlapping buildings: this does happen more often though. See eg changeset https://osmcha.org/changesets/154040205

I guess it is a bit hard to see visually in iD Editor. I am using JOSM, that contains validation tools that flags these issues.

iD Editor suggests to add a layer in case one feature overlaps another. That makes sense when eg a highway overruns a waterway. The highway should get a layer tag (and a bridge tag).

But for buildings that is not the case, buildings hardly ever overlap each other. So the suggestion iD Editor gives is misleading. "Repositioning" should be happening here.

Regards, martien

Hi, thanks for mapping. You requested a review of your mappings.

Your buildings are well mapped. Good location, square corners and precise outline.

There is one exception though: a building with unsquared corners and with a tagging like name=Building. Unlike you know the name of the building (eg. "My Sweet Home", visible eg on a sign post), do not use that tag.

Thanks and regards, Martien, HOT validator.
