Reporters' Roundtable: Maps and mapping (podcast)

This week: Mapping! We'll discuss how maps are made, who owns the aerial image of your back yard, and how to crowdsource mapmaking.

Who doesn't love a good map? But maps aren't what they used to be. Today's "maps" do more than show us what's where: They tell us where we are and how to get where we want to go. Mapping is also now a privacy and security issue. Criminals are using public satellite imagery and street-view photos of structures to plot property crimes. We'll talk about these issues, plus how maps are made, and the as-yet unsolved challenges for map developers, in this week's show. Our guests are Peter Birch, product manager of Google Earth, and Nick Black, cofounder of Cloudmade, a company doing business around the OpenStreetMap project.
