The second application applied VNS to illustrate current and potential future
conditions in Demo Dairy at the paddock level. Ecosystems were assembled from
crop information data (density, species composition, size, etc.) and on the ground
textures were applied in combination with previously developed 3D objects to
each specified paddock according to the farm plan. The rendered images were then
assembled into a 360 degree panorama viewpoint, using Photo Overlay Creator
(
www.casa.ucl.ac.uk/software/photooverlaycreator.asp
) and displayed in Google
Earth as a 'Street View like' interactive photo-overlay (Fig.

b).
Although the outputs presented in Fig.
5
only show 'current on the ground
conditions', they could easily be modified to display potential response scenarios
(from crop modeling runs or derived from adaptation strategies) of the considered
system to environmental changes.
