Regarding residential areas, it would be very helpful to understand how these residential area polygons will be used. For example:
> For digital and/or printed maps show residential areas at small scale and individual buildings at large scale > Distinguish between areas of residential concentration (landuse=residential) and areas of scattered habitation > Compute building density by residential area polygon, to estimate population density and target relief efforts > etc. Knowing more about how data will be used would be useful for all contributors, and may encourage more contributions. A few examples (with images) provided with the task instructions would be very helpful - but I understand the time constraints.
