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

  1. Open Google Earth.
  2. In the left panel under "My Places," right-click the placemark whose altitude you want to change.
    • Windows, LinuxClick Properties and then Altitude. In the "Edit Placemark/Folder" window, choose an altitude setting. For example, select Clamped to ground or Relative to ground.
    • Mac: Click Get Info and then Altitude. Then, choose an altitude setting.
  3. You can enter a value in meters in the "Altitude" field for any setting except Clamped to ground and Clamped to sea floor.
