The Google Maps indoor maps are not Street View maps, but they could still be useful for some teachers and students. You could use the indoor maps for field trip planning. The indoor maps could also be useful if you have your students writing travel narratives about places that they haven't been to. For example, a few years back one of my colleagues and I had students write fictitious travel narratives about places that they had studied during our geography unit. Students had to research places in a city and write a short narrative about visiting those places. The indoor floor plans could provide students with some more details to add to those narratives.
