Global Mapper (www.globalmapper.com) is very useful to both georefence and create KMZ files with image tiles. It costs 349 USD. Here is a description:

1. Export a 200 dpi jpg image from Ocad
2. Open the ocad file or another georefenced map in Global Mapper (it supports many different formats. For example ocad, sosi, shape, geotiff)
3. Open the jpg file and rectify the image. (use the online help if you don’t understand how)
4. Export raster kmz file. Choose a tile size not bigger than 1024×1024 which is default.

@steve: You can get quite a bit in on 3 MB – the problematic limit is the 1 megapixel limit (e.g. 1024×1024). However, you can tile your map into several tiles and put them in the same kmz-file – giving good quality for really BIG 1:15000 maps – should cover most normal races.

you indicate map size limit is 3MB. How big (approx) a piece of a 1:15000 can you you fit on 3MB?

@ts Not in the current version of Mapsource / Trainingcenter as far as I am aware of. But the custom maps are very new (only beta firmware), so who knows what will come later on?
