Hi everybody, First of all thanks a lot for mapping in the Bangladesh tasks! It will be of great help!
And indeed, I should have made it clearer in the presentation. I'll try to do a review tomorrow. In big follow the instructions of althio: for appartment and other large buildings --> * building=yes* for big individual trees which serve as landmark --> *natural=tree* but also bushes and a bunch of trees together which too serve as landmarks --> *natural=wood* for open areas it is okay to map --> *leisure=common* * (but you can use also a landcover <http://wiki.openstreetmap.org/wiki/Landcover>tag for open areas like --> natural=sand or landuse=grass)* Further remarks and clarification: - on buildings; indeed it would be good to collect the levels but don't put effort in it for now. We first need the base map of roads and big landmarks. This is essential to do mapping on the ground. - In this case building=construction is also not recommended. Every day things are changing here. Besides this, buildings under construction have often already inhabitants. Often they are just building one more floor on top of the existing building. (Think back to the catastrophe in Rana Plaza <http://en.wikipedia.org/wiki/2013_Savar_building_collapse>, you get buildings ready to collapes anytime by building like this...) So just stick with building=yes for now. - the leisure=common tag we try to adjust this one during the mapping on the ground If you need more clarifications, if you have questions or if you have ideas to make all this even more smoothly, please give us a sign!
