I have generated a kmz. file of a scanned geological map. But when it is opened through Google Earth, the resolution is very low and cannot zoom in with clear colours.
For raster layers, a value of 0 can be used to create one untiled output image. If a value greater than or equal to 1 is used, it will determine the output resolution of the raster. This parameter has no effect on layers that are not raster layers.
