Gladly.

Knowing that the height_field with the city has a scale of <500, 30, 
500> and is centered on the origin with basis at 0.0, and knowing that 
water level is y=0.60; and with the other side of the river being a 
height_field with the same scale and translated <-250, 0, 0>:

//Camera positions:
#declare SceneLook      = 6;  //0=overview; 1=overview River Harbour; 
2=Ruins; 3=orthographic vertical; 4=orthographic vertical for roaming
                               //5=Sikhara; 6=overside Yann; 7=offshore 
Sea Harbour; 8=birdseye Yann mouth; 9=from upriver;

}

The large angle generates some deformation which are acceptable is these 
kind of panoramic views.

Just ask if you want any more info.
