Change placemark altitudes
You can assign more accurate altitudes for your saved locations, called placemarks, in Google Earth for your computer. You can change altitudes for a single placemark or all placemarks in a folder.
Note: Folders can have placemarks with different altitude settings. In this case, the folder's altitude setting shows as "Mixed Modes."
Altitude settings for placemarks
- Clamped to ground: Altitude is locked to the ground level. You can’t enter an "Altitude" height for this setting.
- Clamped to sea floor: Altitude is locked to the sea floor. You can’t enter an "Altitude" height for this setting.
- Relative to ground: Altitude is relative to the ground elevation.
- Relative to sea floor: Altitude is relative to the sea floor.
- Absolute: Altitude is relative to sea level.
Change altitude settings
- Open Google Earth.
- In the left panel under "My Places," right-click the placemark whose altitude you want to change.
