Hi all,

After several hours of sleep deprivation in order to merge all the needed 
data, and do some checks and compression, the final data set is ready:

Download, and bunzip2 each file ("for i in *.bz2 ; do bunzip2 $i; done"). The 
result should be a set of shapefiles much like the sample dataset (only a lot 
bigger):

The differences between the sample dataset and the final dataset are:
- Data is in epsg:4326 (with .prj files)
- Contour lines span several shapefiles (just load them all, display them with 
the same style)
- Several shapefiles do have spatial quadtree indexes (.qix files). You *may* 
build the missing indexes with mapserver's "shptree" (default depth). Make 
sure you're doing that in a computer with more than 4 GB of RAM, or else it 
will take ages (why do you think they are not provided? wink, wink).
- You *may* build indexes other than .qix, but please tell so in the mailing 
list, and assume defaults - no tweaking at this stage.


P.S.: I guess you already know how bittorrent works. Please seed after a 
complete download.


Enjoy,
