Farm airstrips are a thing that has bugged me for some time. Proper airports appear at zoom 10 and then other airfields, including farm strips appear at zoom 11. Whilst there are significant private and military airfields that should be shown at earlier, is there a tag to inform the renderer

I'm in favor of airstrips, but I would make airstrip a subcategory of runway. So tagging an airstrip as runway is not wrong if you don't know any better. Anyway, is there a way to know if a runway is an airstrip from aerial photos? Is grass surface enough to make something an airstrip? Does this

Re: [Tagging] airstrip vs runway

Just to add some observations about Alaska to this conversation. Alaska has hundreds of long strips whose surface is gravel or grass long ago cleared of woods and brush that served as landing strips for small airplanes. The small airplane is almost as common in rural Alaska as automobiles are in

Re: [Tagging] airstrip vs runway

I know there are some airstrips in SEQ that are privately owned & no-one is allowed to land without permission - should they be mapped as possible emergency strips? There are also charter planes that operate of the beach at Fraser Island - should that stretch of beach also be shown as a 'strip?

Hi, Looks like the tag 'airstrip' has been introduced by a LINZ import. The osmwiki says "The *aeroway =*airstrip** key is used to identify a place such as a farm field, hill slope or similar reasonably flat area where light aircraft can land
