Thank you Dennis, and sorry for taking a while to respond. I had to get our 
technician to set up a Geoserver, which is now done and the GeoTiff is 
uploaded.

I (and the technician!) have some problems understanding the following 
steps. I have tried to read the documentation but I don't get that very 
well either. Could you please expand?

I assume that these things have to be handled through the command line 
interface, which I'm not very savvy with yet.

Thanks again,
Robin
