You may have noticed that I have marked a lot of buildings in Nanaimo with notes indicating that each of those buildings has multiple businesses in it. This is because on the next sunny weekend, I will be going down to Nanaimo to survey all of those businesses, and I need to be able to see at a glance which specific buildings I need to survey. I will need to know the exact position of each business within each building, so what I end up putting into OSM as a result of this survey is an as-accurate-as-possible depiction of each building’s “floor plan”, if you will.
