Modeling and texturing an Island

[Sketchrender]

Good morning.

I have to model a small island, and map a aerial photo on to it using formz 4.2.

I have done it before but never with any great accuracy.

Modeling the island is not the problem as the terrian modeler is quite good in formz.

It is texuring the aerial image on to it is a bit hit and misss, and the memory always shoots up.

 

Any advise ?

 

 

thank you.

 

I wish formz had referencing, may be one day.
