Just a minor addendum to Mister Blue's reply; the Kokua viewer allows
for mesh upload up to 256 meters in size. So far as I'm aware, it's
currently the only viewer that does.
Also, out of the box, a Blender unit does not equal one meter (they're
quite a bit larger). To make sure that you are working with meters in
Blender 2.5 or newer, you will want to check the Properties pane, then
the Scene options, which contain a section named Units. Make sure this
is set this to Metric.

I have created terrain meshes using Blender and various manipulations.
A very good tutorial for creating terrain meshes in Blender is
http://www.youtube.com/watch?v=g2EMquDN7qQ which goes through the
steps of sculpting and painting a new terrain. Blender also has a mesh
deformation based on an image so it is easy to do a heightmap or
pre-existing RAW file import.
If you are making a mesh for a whole region (256x256 meters), one
"trick" is to create a mesh that is 256x256 in vertices but is only
64x64 blender units. The viewers only allow importing meshes smaller
than 64m in any dimension so you must create your terrain mesh no
larger than that. But OpenSim has a console command for resizing
objects. So, you create your terrain mesh 64x64 blender units (which
become one OpenSim size unit which is one meter), import the mesh, and
then, on your region's console, do a "edit scale theObjectsName 256
256 properScaleForZ" where "properScaleForZ" is the Z size noted at
import time times 4.
