Earth Builder Help. Opacity Control for Google Maps v3 Overlay. An opacity control / transparency slider inspired by Klokan Petr Přidal's original Opacity Control for Google Maps (v2) Overlay. Borrowing from the original design but completely re-coded to work with the radically different Google Maps API v3. Originally developed for use on NZ Topo Map, the essential components have been cleaned up and extracted for easy re-use in your own web sites.

Google Floorplans. “Where am I?” And “What’s around me?” Are two questions that cartographers, and Google Maps, strive to answer. With Google Maps’ “My Location” feature, which shows your location as a blue dot, you can see where you are on the map to avoid walking the wrong direction on city streets, or to get your bearings if you’re hiking an unfamiliar trail. Google Maps also displays additional details, such as places, landmarks and geographical features, to give you context about what’s nearby. And now, Google Maps for Android enables you to figure out where you are and see where you might want to go when you’re indoors.

When you’re inside an airport, shopping mall or retail store, a common way to figure out where you are is to look for a freestanding map directory or ask an employee for help. Starting today, with the release of Google Maps 6.0 for Android, that directory is brought to the palm of your hands, helping you determine where you are, what floor you're on, and where to go indoors.
