Hey everybody.

I have some questions about the maximum file size of a kml/kmz file.

1. Is there a maximum file size?
2. My kml is about 30 MB and the zipped kmz about 6 MB. I connected it with Google Earth via a Networklink. It works, but my machine is nearly breaking down everytime i use the link. I´m using a Intel Pentium III processor with 924 MHz and 512 MB RAM. Is my machine too slow?
3. Is there a way to make kml/kmz files smaller?


Thanks

Hello,

Welcome to the GE Commnuity!

I don't believe that there is a defined maximum size but, clearly, there comes a point where things start not to work very well. As you suspect, this is probably more to do with your machine. My SNCF collection is about 700k when compressed to KMZ; it's just about OK on a 900MHz machine but is unusable on a 600MHz machine (that's a very unscientific test of course).

Yes, remove some of the data from it! Unfortunately, that's what KMZ is designed to do. Yes, it's probably possible to get a marginally smaller file with a different compression algorithm but it wouldn't work with GE and probably wouldn't help you GE still needs to process all of those objects - whichever way the data is presented.



Cheers,

Simon.

Hi Bigga,

One thing you can do is try to break down the file into separate network links, each one downloading a small portion of what you need. Another thing you can do is work with Regions to break down the area displayed so that GE isn't trying to download and display everything at once.

Just a quick follow-up to the other advice:

--You can put multiple KMLs in a single KMZ: your Network Links can all reference other KML files stored in the same KMZ.

--Using a Regions-based hierarchy, you can cut down on the amount of KML the browser has to parse at any one time.

Thanks everybody. I splitted the kml and i´m now working with regions...it works!

Thanks for your support.
