Imagery is from 2011 and part of the road location has changed and was updated accordingly.

By the way, I forgot to supply this resource for "sandbox" editing. osm.wiki/Sandbox_for_editing

Please don't upload intentionally incorrect features. There's no rectangle motorway in this area. If it was for a test, don't leave the data on the server for 6+ hours.

Hello Dahyun Whang,

I have been cleaning up the data in this part of Madagascar and wanted to offer some advice.

When naming buildings or roads please only provide a specific name for the feature. If you do not know the name of a building or road then it is best to leave it blank. Additionally, naming the type of road via the "name" tag like "Residential Roads" or "General Building" is unnecessary.
Here's the OSM Wiki page on naming conventions: osm.wiki/Names

Finally, please be careful not to duplicate ways. I noticed a couple ways which looped around and drawn over itself or separate features placed on top of one another. The JOSM validators caught these and I have since fixed the issue.

Thank you for helping map in OpenStreetMap!
