Looks great! Thanks for mapping, please keep it up!

Thanks for mapping! Make sure your buildings don't overlap. You may need to zoom in closer to make sure they don't.

Looks great! Thanks for mapping

Thanks for mapping! Make sure to watch for buildings that are overlapping -- you may need to zoom in pretty far to be certain. I deleted the extra building here

Looks good! Thanks for mapping. Don't forget to right click on each building and click the "square" building tool so the buildings have right angles (90 degree corners)

Thanks for mapping, welcome to OpenStreetMap! When mapping rectangular things like houses don't forget to "square" the corners to make them 90 degrees by hitting 's' on your keyboard after mapping the building. Thanks!

Hi, thanks for mapping! However it looks like two of the ways you added, osm.org/way/598220756#map=13/-1.3712/10.6324 and osm.org/way/598220763#map=13/-1.0780/10.5578 are already mapped, so we are going to remove them. Don't forget to look for existing roads when mapping

Thanks for your contributions! Don't forget to tag each building as "building" though, otherwise they are just empty shapes. Also make sure to ensure they are the right shape, most buildings will be rectangular or square. You can click the 's' button on your keyboard to make the corners 90 degrees. Thanks for mapping!

Hi Alexandra. Primary and secondary roads should only be the most important highways in a country. These are small rural roads that should be unclassified or residential. Check out the Africa Highway Tagging page: osm.wiki/Highway_Tag_Africa

Hi Peter. This road already existed when you added it (osm.org/way/588421617). Please check for existing roads before adding new ones. Thanks for mapping!

In particular, this corner: osm.org/node/2833603505#map=19/12.98507/7.61232

You can learn more at learnosm.org , I'd recommend reading that site

Hello, you mistakenly dragged a corner of the road, so there is a big triangle now. We can fix it, but make sure to be careful with what features you are moving. Thanks for mapping!

Hi Usman,

Thank you for contributing to OSM! It is best to represent each road with only one feature. You are adding some roads that already exist. Please look for an existing road before adding a new one. Let me know if you have any questions. Here is more info osm.wiki/One_feature,_one_OSM_element

Great, thank you!

Hello, thanks for your edits! I think the top of osm.org/way/588867619 is a little off though according to imagery, it is currently going through parking spaces. I think it should go farther east and then turn 90 degrees

Hi there, thanks for your edits! However I think the highway=service you added should probably be either highway=residential or highway=unclassified, it looks like a regular through street. Also I think the small segment (osm.org/way/588875194) should be part of the main way, and the round part should be its own way. Let me know if you have any questions.

Hello sev_osm,

I saw your earlier edits fixing some of the villages that were previously mapped only with primary roads, thanks!

However, in this changeset and other road classification changes you recently made in Nigeria and Chad, you have incorrectly downgraded several major roads to tracks. In most of these changes the road includes a ref= tag, are paved, and serve as connectors between major cities. Per the Nigeria project page all federal roads should be primary osm.wiki/WikiProject_Nigeria#Roads and the changes also don't match the Highway Tag Africa guidelines.

Can you please revert these changes? Since there are quite a few, you may also want to ask for some additional help from the Data Working Group. Thank you.

Hi there, welcome to OpenStreetMap! I see you are adding some highway=motorway -- that means a controlled access, divided highway, like an interstate highway in the US or an autobahn. In this case this looks like a much smaller road. Please refer to the task instructions for your HOT task and follow them, in this case it asks only for buildings. You also might want to ask whoever organized your event for help. Thanks!

Hi there, welcome to OpenStreetMap! I see you are adding some highway=motorway -- that means a controlled access, divided highway, like an interstate highway in the US or an autobahn. In this case it looks like a small dirt road. Please refer to the task instructions for your HOT task and follow them, in this case it asks only for buildings. Thanks!
