In the file selection window, ensure that you select GeoTIFF from the file type dropdown. Navigate to the location where your GeoTIFF is stored and select it.
Step 5: Confirm Your Selection
After selecting the file, click Open to proceed. This brings you back to the Google Earth interface.
Step 6: Create a Super Overlay
The best method for importing large GeoTIFFs is to create a Super Overlay. This option helps manage the resolution effectively.
Step 7: Adjust the Resolution
Keep the resolution at a high setting to ensure clarity of information displayed on the GeoTIFF. This is crucial for maintaining legibility.
Step 9: Finalize the Import

FAQ
What is a GeoTIFF?
A GeoTIFF is a raster graphics file format which is a standard for georeferenced raster data. It includes geographic metadata to enable the image to be positioned accurately on the earth’s surface.
Why use a Super Overlay?
A Super Overlay allows large images to be displayed in Google Earth without overwhelming the system. It splits the image into tiles based on the zoom level, ensuring smooth performance.
What if my GeoTIFF does not display correctly?
If your GeoTIFF does not appear correctly, check if it is properly georeferenced and in a compatible format. You may need to use GIS software to verify or adjust its settings.
Does my GeoTiff need to be 3 bands ( RGB)?
Yes, 3-band RGB images are the only type of GeoTiff that Google Earth can import & display
