There's an interresting thread running on the advanced board covering the quality of your english. http://www.opengl.org/discussion_boards/ubb/smile.gif

The simplest way might be to just use quads. But you can't interpolate the height values with this easy attempt, so if the density of your iso-map is not high enough and the values change heavily you'll get ugly results.
There are however great (and complicated) algorithms to interpolate an iso-map (ever heard about "surfer"?). You could then increase the resolution only at places where necessary.

Surfer is a software which can create smooth height-diagrams out of a raster of height values. It's a great example for what I mean.

might want to take a look at this (http://www.gamedev.net/reference/programming/features/gpgenesis8/) . It's based on DirectX ( i think ), but the theory there is pretty solid. If you're looking to make your standard tile engine, the link above will probably be a good start. I agree with Michael that simple quads will work just fine, but that nagging voice in my head always screams "triangle strips!"

Yes of course you'll be doing strips, but the theory stays the same... http://www.opengl.org/discussion_boards/ubb/smile.gif=
