Height field most probably, or isosurface. However, you will have to process
your contours to coloured bands (light for higher parts; dark for lower
parts). You can do this in any painting program. Make sure you
smooth/blur/blend the limits between colours. Then you can use this image in
a height_field, but also with an isosurface, as a pigment function.
Earthworks/platform can also be made on the image in a paint program.
However, if you have a height field generator like Leveller for instance,
that would even be easier to make.
You can place objects with the trace() function of POV;

Hope this helps,

Thomas
