It will create a root KML and possibly 1000s of linked KMZ files each with a PNG or JPEG image tile. Depending on the size it may take a couple of minutes. Pick a directory where the generated files will be created and wait for the conversion. To get started using the WATERSKMZ Tool visit the WATERSKMZ tutorial. The current release of the tool requires the use of Google Earth version 5.0 or higher. Simply drag the TIF file onto Google Earth map after which you will be prompted to create a "Super Overlay". The WATERSKMZ Tool is a compressed Keyhole Markup Language (KML) file that provides easy access to geospatial WATERS data and services.

But very large files will still need to be reduced in size one way or another.įor large GeoTIFFs files, Google Earth Pro has an option to create a super overlay and a series of KML and image tiles which change resolution when you zoom in & out. To export a KMZ file, follow these steps: Select File > Export > 3D Model.
A KMZ can contain location data (latitude and longitude) along with other information, such as SketchUp geometry. There are some tips to manage your saved places. The KMZ format is a zipped form of Google Earth’s proprietary Keyhole Markup Language (KML). You can streamline Google Earth with more memory for user-defined files if you turn off all layers and other saved places. Note KMZ files are unpacked and loaded into memory so it's the unpacked file size that is the limit not the compressed KMZ file size. Google Earth itself needs memory set aside for the app, base imagery, and layers leaving the rest for user-defined KML and KMZ files. Google Earth is a 32-bit application and is limited to 2GB memory and a 2GB disk cache. A superoverlay is a KML structure that allows you to load a tiled version of your image, so that it shows a few tiles at low resolutions, and loads just the tiles it needs for your current view area at higher resolutions. You can also turn your image into a KML superoverlay with other 3rd party tools. When you save a placemark or folder from your Places panel you have the choice to save your content as a KMZ file or a KML file.

As others have suggested, I would try Google Earth Pro (now free for everyone), which can import a very large image, and will give you options to crop it, down-res it, or create a superoverlay. You can easily create KMZ files using Google Earth. So you can bring in an image up to that size on your machine, but a machine with a weaker graphics card may not be able to render the same image. Most are 4096x4096 or 8192x8192, though some are lower and some are higher. If you go to Help > About Google Earth (somewhere else on Mac), you'll see a line about "Max Texture Size", which indicates this limit. The maximum image size you can load into Earth for an Overlay is based on the capabilities of your computer's graphics card. Your limit is likely not the file size (though 2gb is pretty massive), but rather the image size in pixels.
