[Talk-ca] GeoTiff in JOSM

Two options

1. Covert to tiles with gdal2tiles or another program.
2. Set up MapServer and server it with WMS

1 is faster at serving tiles but takes more disk space and pre-processing. 2
is slower but better for large files since you don't have to pre-process.

As your GeoTiff isn't very large, the first is a viable option. I'd guess it
might take me a week to process. 

MapServer is a pain to set up, as you've discovered. If you're running
Ubuntu I could show you my .map file if it'd help.
