X-Plane11 UHD Mesh Scenery v4 / Lyndiman's New Zealand Ortho

I have downloaded both X-Plane 11 UHD Mesh Scenery v4 for New Zealand and Lyndiman's New Zealand Orthophotography. I use a Windows PC.

Before I install anything, do you install one or the other or can the UHD Mesh be used as a "foundation" for the Orthophotography?

Finally if it is either/or which would you recommend?

Thanks

Kevin
