I've been to a few [Missing Map][1]s events now and a lot of the time the task is to trace buildings. I always wonder what is the benefit of mapping the building outline instead of as a single point node? It's a lot faster to map buildings as nodes, and you still get an idea of where dwellings are located. How does the exact size and shape of the building help for humanitarian purposes?
