Hi Vilko

Depending on the model you're using to calculate the losses, the terrain factor is a number which should include the geoclimatic and particular terrain factors that will affect the propagation. It's usually significant in long haul links.
If you can get a hold on the ITU recommendation P.530-7/8 there is a good explanation there.
Also a simpler explanation is at:

but is closer to Vigant-Barnett model, which I find not very accurate.
