Small DEM's?

[MeowRailroad]

Are there any DEM's that have fewer than 40 baseboards? I want to build shortlines and don't want to use a big DEM as there is no easy way to delete all the excess baseboards.

When creating the DEM, can't you set the area size (and as a result the number of baseboards)?

I was asking about already made ones, as I don't have TransDEM and don't have the money to get it. Also it most likely doesn't work on Mac.
