Dear Subrata Debnath,

you seem to be adding a lot of building footprints all across the globe and it is very unlikely that you have first-hand knowledge of the areas you are active in.

When working with RapID and the Microsoft building footprints, please always do the following:

• ensure that the local community is ok with Microsoft building footprints being used in the region. In some regions this data is exceptionally low quality and unwanted by the local community. Make contact via community.openstreetmap.org before you edit.

• visually check the building footprints you are adding against the best available aerial imagery in the region (which can often be different from Bing imagery) and ensure that you’re not uploading low-quality or outdated buildings.

Please also ensure that you use good changeset comments (e.g. “added buildings in NAME_OF_REGION”) and not “#youthmappersatirs #irsju” which is not understandable to the majority of the OpenStreetMap community.

Please inform other members of your team accordingly.

Thank you
Frederik Ramm
