For a good example, see the bottom of this page, where I have an example of one map with two different 'number of tiles.' This, along with the native resolution of the original image you are using to create the KMZ means that there is NO WAY to predict what will look good when converted to 1024 x 1024 pixel tiles for a KMZ. So it looks like you're good to go.Īs the astute reader will realize, the restriction on a 1 MB JPG image with no limit on the actual area covered means that the pixels per mile (or foot, or meter, or whatever) is completely variable when creating KMZ files. And since you are stating that the KMZ file size is 123 Kb, it must be less than 1 MB, since the zip-based compression of a KMZ file isn't good enough to get a 1 MB file down to 123 Kb. mile KMZ will work fine, as long as the image is less than 1024 by 1024 pixels.

To the original poster: the bottom line for you is that yes, your 62 sq. There are various threads that support this finding. Note: Garmin says that images larger than 1024 x 1024 are 'rendered at reduced resolution.' As far as I can tell, this is incorrect - they are not rendered at all. And the number of tiles in the KMZ is only limited by the number of tiles supported by the device (100 tiles for most GPSr, 500 for the Montana series). You can create a KMZ file that has multiple tiles, where each tile is limited to 1 MB.

That usaully means one JPG that is 1024 by 1024 pixels (although it could be any combination - you could do 2048 x 512 pixels or some other combination that multiplies out to 1,048,576 pixels).

Or does your 32 MB KMZ have multiple tiles? That would be fine.Īs stated by Garmin, for all their KMZ-compatible devices, they only support tiles that are 1 MB in dimensions. Are you suggesting you have a KMZ file with a single tile, 32 MB in size, that works on a 62s? I don't think that is possible. Not at all, I have one that is over 32,000 Kb
