Alphonce, thank you for your additions to OSM. It appears that you have added the area of vegetation along the Rovuma river rather than the actual water surface. Do you have other information in this location besides Bing imagery?

Thank you for the help mapping Tanzania. Please note that OSM standards do not allow snapping of building nodes to roads or paths.

Do you have a more accurate location for this church? There doesn't appear to be a building at this location.
Thanks

Thank you for your first contribution to OSM, buildings should be traced accurately with square corners. Use the q key please. Thank you.

Thank you for the help mapping. Please make the building polygons orthogonal by using the q key.

Thank you for your first contributions to OSM, your help is appreciated. Please note that when creating a building polygon it is important to not snap a node to an adjacent feature like a road.
Please keep mapping.

Congratulations on your first contributions to OSM, we appreciate the help. Please look over the project instructions to learn how to create square corners on the buildings. Use the q key. Thank you.

Thank you for your interest in mapping Ethiopia. Please note that OpenStreetMap is not a game and users should only map existing features. I have reverted these features.

@martinairmaps Thank you for supporting OSM in Malawi. It seems that the areas you identified as buildings along the M26 Highway are actually stockpiles from the road construction works. Please look at the Maxar imagery to get a different perspective. Thank you

Thank you for your interest in OpenStreetMap, we need local knowledge. Please look over the Africa highway tagging guide to help understand proper tagging. osm.wiki/Highway_Tag_Africa

Thank you for your efforts to map Tanzania. Please use the online resources to learn how to accurately map buildings. The HOT project instructions are a good resource.

Thank you for helping map this project, we appreciate the square corners on the buildings. Please note that the building footprint should be an accurate representation, not an oversized polygon. Thank you

This airport does not appear to exist. node/1042089497

Thank you for helping map in Tanzania. Please note that building outlines need to be accurately traced.

Congratulations on your first edit to OSM, thank you. Your edits look good.
Please be careful of snapping buildings to roads and paths.

Thank you for contributing this valuable railway information to OSM.
What are the tags for the curves/circles coincident with the railway alignment?

Please work to follow the instructions for tracing buildings.

Thank you for your first contribution to OSM. Please read and follow the instructions for the tasking manager to accurately trace each building. Thanks

Great, thank you.

Congratulations on your first edits to OSM in Tanzania. Please use the online materials to learn how to accurately map buildings. Us the q key to make the corners of buildings square. Thank you.
