Texture a height map

Newbie & Debugging Questions
#1

Right, now that I can no longer fall through the height map: How would you texture a it?
My height map stores a 2D array of height values, when I render the map I have a nested for loop that places a vertices where the need to be.


for (int z = 0; z < values.length - 1; z++) {
     GL11.glBegin(GL_TRIANGLE_STRIP);
     for (int x = 0; x < values[z].length; x++) {
          GL11.glVertex3f(x, interpolateHeight(x, z), z);
          GL11.glVertex3f(x, interpolateHeight(x, z + 1), z + 1);
     }
     GL11.glEnd();
     GL11.glFlush();
}

I have tried to place a texture co-ordinate at every vertex but that caused a lot of lag and a hideous image.
What is the most effective way to texture a height map and how would I do it?

thanks in advance,

Are you looking for 2D top-down image or a 3D height map that you can view from different angles?
