Are folks still getting lost in the faux marble expanse of your airport or shopping mall, even after you've uploaded the floor plan to Google Maps? Then maybe it's time you went the extra mile and improved indoor mapping
using the official Floor Plan Marker app. It instructs you to walk around the "entire surface" of your place of interest, while gathering position data from GPS, public WiFi signals and cell towers. Once added to Google's database, this extra info will allow the familiar blue dot to function on your customers' Android phones even when your actually-concrete building gets in the way of their satellite signal. The app's already available at Google Play, so go ahead -- make the schlep now so that others don't have to.
