[OSM-talk] [talk-au] Fwd: Re: Why PD is not better for business

James,

I am sure there are other examples of things that can't be easily
mapped by humans walking, cycling and kayaking around (drains,
underground tunnels and long lines of electricity pylons spring to
mind). Luckily street maps don't usually depend on these things to be
useful.

For example rather than painstakingly crafting the entire coastline of Australia from a few GPS traces and a lot of imagery (much is relatively inaccessible), we can import it from someone's dataset and spend that large amount of time doing other things to improve OSM that we can't import data for.
