Files .kmz do not open in Google Earth. It shows an white square and a red cross. Any ideas?
If you’re getting a white square with a red cross:
Red Xs appear on Google Earth when the computer is unable to render the file at the specified resolution. This is dependent on your computer- we have seen that a Macbook Air is unable to render past 10cm/pixel on larger maps, for example. We recommend starting with a lower resolution file (50 cm or 20 inches/pixel) and working your way down to the highest resolution that your computer can manage. Another suggestion is to export maps as a set of tiles rather than a single file- you could then break up the rendering into more manageable segments.
